五轴编程教程.

数控五轴加工中心编程的方法及步骤小伙伴！今天咱们来唠唠数控五轴加工中心编程这个事儿。

一、了解加工零件。

咱得先好好看看要加工的零件长啥样。

就像认识新朋友，得知道它的轮廓、尺寸、精度要求这些。

你得清楚哪里是平面，哪里是曲面，有没有啥特殊的形状。

这就好比给零件做个全身检查，心里有数了，编程的时候才能有的放矢。

二、确定加工工艺。

这一步可重要啦。

要想清楚用啥刀具合适呢？大零件和小零件用的刀具可能就不一样。

还有切削的参数，就像炒菜放多少盐、多少油一样，切削速度、进给量、切削深度都得定好。

这得根据零件的材料来，要是硬邦邦的材料，那切削参数就得小心调整，不然刀具可能就受不了啦。

工艺路线也得规划好，先加工哪里，后加工哪里，就像规划旅行路线一样，得合理安排。

三、建立坐标系。

这个就像是给零件在加工中心里找个家。

确定一个原点，然后X、Y、Z轴就像房间的坐标一样，每个点都有自己的位置。

五轴加工中心还有两个旋转轴呢，这两个轴的坐标系也要确定好。

这就像给零件的每个部分都贴上了地址标签，加工的时候刀具才能准确找到地方。

四、编写程序。

现在就开始正儿八经写程序啦。

用那些编程代码，像G代码、M代码之类的。

比如说G00就是快速定位，让刀具快速跑到指定位置。

编写的时候要按照之前确定的加工工艺来。

如果有曲面的话，可能得用一些特殊的编程方法，像宏程序之类的。

这就像写作文，要按照一定的逻辑和规则来写，不能乱写一气。

五、模拟加工。

程序写好可别着急让加工中心干活。

先模拟一下，就像演习一样。

看看刀具的路径对不对，有没有可能撞到零件或者夹具。

要是模拟的时候发现问题，那就赶紧修改程序。

这就像出门前检查一下东西有没有带齐，发现没带钥匙还能及时补上。

六、实际加工。

经过前面的步骤，没问题啦，就可以让加工中心开始干活啦。

不过在加工的时候也不能完全不管，得盯着点。

万一有啥突发情况，像刀具磨损啦，还能及时处理。

数控五轴加工中心编程就是这么个事儿，看起来有点复杂，但是只要一步一步来，多实践，肯定能掌握的。

pm五轴编程案例
以下是一个简单的PM五轴编程案例：
假设我们有一个PM机器，需要使用五轴进行加工。

下面是需要加工的零件的三维模型：
![part_model](
我们需要对这个零件进行腔加工，即通过一个球形刀具在零件内部凿出一个空洞。

我们可以先使用CAM软件生成一个五轴刀具路径，然后将其导入到PM机器中进行加工。

接下来是五轴编程的步骤：
1. 确定坐标系和工作原点：
在进行五轴编程之前，我们需要确定机器坐标系和工件坐标系，并将工作原点设置在正确的位置。

2. 设置刀具：
根据CAM软件生成的五轴路径，选择合适的刀具，并设置它的切削参数，例如
刀具长度、直径和切削速度等。

3. 确定加工路径：
根据CAM软件生成的五轴路径，确定刀具的加工路径。

此步骤通常需要在PM 机器上进行实际操作来调整加工路径，以确保刀具能够完全进入工件内部。

4. 编写五轴程序：
根据确定的加工路径编写五轴程序。

程序应该包括刀具路径、刀具转速、进给速度以及对工件和刀具的安全保护措施等。

5. 载入程序并进行加工：
将编写好的五轴程序载入PM机器，并进行加工。

在加工过程中，需要监测刀具和工件的状态，以便及时采取措施避免损坏。

通过以上步骤，我们可以完成一个简单的PM五轴编程案例。

在实际应用中，编写五轴程序需要考虑更多的因素，例如刀具路径的优化、加工效率的提高以及程序的可读性和可维护性等。

He must know how to activate parts, create and edit toolpaths.2 General Principles for 5-Axis MachiningThe G3 V19 version of WorkNC is delivered with twenty 5-axis toolpaths. All of them are milling toolpaths, except a drilling toolpath and a laser cutting toolpath.The surface part construction is very important when using 5-Axis toolpaths. In most cases, the tool orientation is directly linked to the U and V parameters of the surfaces.Most toolpaths require the use of context surfaces to select the surfaces to machine, others require the use of one or more guides curves, etc.For 5-axis machining, a surface is made of a profile and a face. The position of the tool on the surface depends on the selected toolpath, especially for "rolling" and "profiling".E.g.:Surface to machine:Rolling:Profiling:Machining normal to Surface:5-Axis Machining ParametersMachining Zone and Surface Selection for 5-Axis33 5-Axis Machining ParametersAll standard parameters may be used, except boundary curves and machining planes which are never used for 5-axis machining.1.

Selection of the change of direction in corners 8. Position of the tool on the surface 9. 5-Axis Parameters10. Surface in relation to which the tool is oriented3.1 Machining Zone and Surface Selection for5-AxisIt is not possible to use "Boundary Curves" or "Machining Planes": only Window and View parameters are available. In some cases, the use of a view allows defining which side of the surfaces are machined. This is for example the case for the Perpendicular to surface toolpath.3.2 Selection of the 5-axis machining methodYou can usually choose any of the threeavailable machining methods. This means that the direction of the guide curve as it wascreated has no importance.NOTEStart point of the guide curveWhen using a closed curve, the point used as starting point to create the guide curve is important since the toolpath will start from that exact point.35-Axis Machining Parameters Selection of the tool orientation3.3 Selection of the tool orientation(5-Axis) Machining Direction Dialog BoxSurface definitionFor 5-Axis programming, it is very important that surfaces are correctly defined: the tool orientation depends on the U and V parameters of the surface. Surfaces must have been properly prepared before programming a 5-axis toolpath. E.g.:Surfaces not correctly defined...... wrong toolpath:Surfaces correctly defined... toolpath is OK:The example illustrated with the four images above is a clear representation of the problems that you may encounter. If the U and V surface parameters are not correct and if you choose to follow surface ISO lines, the toolpath may be incomplete or the position of the tool may be wrong. The only solution: change the surface(s) using CAD functions.Other example with wrong positioning of the tool:5-Axis Machining ParametersSelection of the tool orientation3Surfaces not correctly defined...... wrong toolpath:Surfaces correctly defined...... toolpath is OK:The above example shows another type of problem that you may encounter: if the U and V parameters of the surface are not correct and if you chose to follow surface ISO lines, the toolpath may be fully completed but the position of the tool may be wrong. Again, change the surface(s) using CAD functions.In case of problems when following surface ISO lines, you can also try the other option called "Perpendicular to curve": it may give better results.(5-Axis) Machining Direction Dialog Box - Perpendicular to CurveFollow surface ISO lines: Perpendicular to curve:35-Axis Machining Parameters Lead-in selection3.4 Lead-in selectionIf you have enough room to position your tool outside the machining zone without any risk of collision with the part or any clamping equipment, you can choose among different machining lead-ins, depending on your own preferences.Radial lead-in with tangency extensionVertical Lead-inRadial Lead-inLead-in with tangency extension3.55-Axis Machining Parameters35-Axis Parameters 3.6 5-Axis ParametersMaximum head rotationThis parameter is used to specify the rotation amplitude ofthe machine head not to be exceeded. This maximumamplitude directly depends on the technical constraints of themachine. When the inclination angle of a surface to machineis higher than this value, the toolpath does not give anyresult. This parameter does not apply to all 5-axis toolpaths.This parameter allows you to indicate the machine capabilityto reach such angle values or not.1. Vertical head 0°2. Maximum amplitude from – 40 to + 40°The opposite picture illustrates this amplitudeparameter. In this case, a surface to 45° could not bemachined.Vector tolerance for smoothingThis parameter allows defining a maximum angle within which the tool can be adjusted onits axis to obtain a smoother toolpath and avoid vibrations of the machine head. If you setthe value to 3°, each of the vectors can "deviate" by a maximum of 3°. This parameter isalways combined with the smoothing distance.35-Axis Machining Parameters 5-Axis ParametersSmoothing DistanceThis is the length over which WorkNC tries to smooth the toolpath. This value applies both forwards and backwards with respect to each point of the toolpath and in the machining direction.Smoothing vector (5°) Smoothing Distance: 1 mmSmoothing vector (45°) Smoothing Distance: 30 mmsVector toleranceThis parameter offers the possibility of reducing/increasing the number of points in atoolpath. If consecutive point vectors along a longitudinally straight section of the toolpath have vector angle variations within the limit of this user defined tolerance, then these points will be eliminated. This tolerance cannot exceed 5°.Setting this parameter with a small value can be useful when working on recent millingcenters with the latest CN controllers which function better with toolpaths containing a large number of points. Alternatively, a higher value will produce a smaller number of points which is more appropriate to older generation milling centers.Vector tolerancePicture 1: Tolerance = 1° Picture 2: Tolerance = 4° Picture 3: Tolerance = 0.1°5-Axis Machining ParametersCurve Machining Options33.7 Curve Machining OptionsBasically, these options operate in the same way as 2D toolpaths for which he same type of parameters is available.Z-steps are completed to gradually approach the curve to machine.These parameters allow you to machine directly onto the surface or to proceed by level, especially during the roughing phase which requires large quantities of material to be removed.Examples :Approach of the curve from + Z:Approach of the curve in the view plane:Machining order, by level:Machining order, by curve:NOTEMachining OrderMachining by curve is similar to machining by zone in 3D toolpaths. The toolpathmachines an area completely then goes machining the next area. When the "by level" option is selected, the number of retracts in the toolpath is higher.3.8 Selection of the guide curve3 5-Axis Machining ParametersSelection of the change of direction in cornersToolpath Parameters - Curve to machineYou must specify the curve to machine. Note that "Curve to machine" means the drive curve.3.9 Selection of the change of direction incornersThe "non-tangency condition" allows managing changes of direction in sharp corners. Twooptions are possible: radial or by segment.Radial:5-Axis Machining ParametersSelection of the change of direction in corners3 By segment:NOTE By segmentWith the "Segment" option, the edge to machine is protected as the tool does not "roll" on it.35-Axis Machining Parameters Tool Offset Distance3.10 Tool Offset DistanceThe Tool Offset Distance parameter defines the axial distance between the center of the tool tip or tool end and the perpendicular point of the curve on the tool axis. By default, if the value is set to 0, the center of the tool tip or tool end is positioned on the curve during toolpath calculations.Picture 1:Picture 2:1. Surface to machine2. Curve to follow and upper surface (2/2a)3. Lower surface4. Controlled point of the tool (center of the tool)5. Offset distanceThe picture # 1 shows the theoretical position of the tool against the machined curve. The picture # 2 shows the position of the tool with an offset value which corresponds to the tool radius.Toolpath example:With a negative offset3.11 Tool Offset AngleThe forward offset angle allows you to define a lead or lag angle with respect to the normal to surface position along the toolpath trajectory.Defining a positive value will result in a lead angle (forward inclination) and a negative value will give a lag angle (backward inclination).This promotes better cutting conditions and improves surface finish quality.5-Axis Machining Parameters3Tool Offset AngleForward Offset Angle = 10°1 Surface2 Tool trajectory direction3 Toolpath pointA positive value of 10° has been entered for the above example so the tool will be inclined in a forward direction with respect to the tool trajectory direction.This specific parameter is not available in all 5-Axis toolpaths but can be used for 5-Axis Planar Finishing, Normal to Surface, etc.5-Axis Rolling Tool Offset Angle445-Axis RollingThe Rolling strategy is used - among others - for part trimming.5-Axis Rolling machines with the side of the cutter, tangent to the surface and following the user-defined curve as illustrated in the following diagram.5-Axis Rolling Machining Principle1 Surface2 CurveYou can use this toolpath both for the roughing or finishing phase.NOTESurface constructionThe surface construction is very important when using the Rolling strategy: surfaces must be perfectly ruled.E.g.:45-Axis Rolling Tool Offset AngleRolling: lead-in with "tangency extension"1. Machined surface2.

The blue surfaces aredefined as the Guide Surfaces and the Curve to Machine is the yellow curve at the base ofthe island.The resulting toolpath is as shown below.Generated 5-Axis Rolling ToolpathLet’s now take a look at a zoomed view of the cutter tip at a point on the toolpath todetermine its position with respect to the flat surface defined for machining in the SurfaceGroup.5-Axis Rolling45-Axis Rolling - Machining StrategyZoom on Cutter TipYou can see in the above screenshot that the extremity of the cutter makes contact with the flat surface defined for machining (the stock allowance = 0 in this toolpath).If we generate the same toolpath but we define the flat surface as ‘ignored’ in the Surface Group, we obtain the following result.Zoom on Cutter Tip - Ignored SurfaceAs the tool is tangent to the inclined Guide Surfaces and the surface below the cutter tip is programmed as ‘Ignored’, the cutter effectively machines this surface.4 5-Axis RollingLab: 5-Axis Rolling4.2 Lab: 5-Axis RollingOpen the 5axes_1 workzone and create "Rolling" toolpaths by machining the undercutgroove.Use the 5-Axis toolpath parameters to create both 5-Axis roughing and finishing cutterpaths.5-Axis Pocketing555-Axis PocketingThis toolpath has been designed for machining tubular forms (e.g. inlet manifolds). You can machine inclined walls and undercuts without having to define different views to access these areas. The toolpath starts at the top of the pocket and mills deeper.Tool Axis ControlAngle and attraction point...When using both an angle and an attraction point, WorkNC draws a dummy cone whose end is the center of the tool tip when in contact with the surface and inclined to the specified angle value .In this case, the tool is oriented to the specified angle, in the direction of the attraction point.This orientation applies for all points on the toolpath, provided however that the attraction point is correctly positioned.Attraction Point...55-Axis PocketingWhen using an attraction point only, the tool is actually oriented with respect to a line going from the center of the tool tip to the attraction point when the tool is in contact with the surface.This orientation applies for all points on the toolpath, provided however that the attraction point is correctly positioned. When the attraction pointis not properly positioned for a given point on the toolpath, a new position is calculated by WorkNC to avoid collision.Z-Step...You can only use a Z-level machining method. The Z-step value can be fixed or variable. The view that you define is very important since each of the Z-steps in the toolpath is made accordingly. Z-steps are calculated in the plane of the view as shown in the picture below.Cutting direction...You can select a curve to indicate the cutting direction.5-Axis Planar Finishing6Lab: Planar Finishing6 5-Axis Planar FinishingThe Planar finishing toolpath is identical to the 3-Axis strategy. You can use it to machinelarge parts using ball-end or flat tools. The 5-Axis strategy offers the advantage that the toolis always normal to the surface machined or some angle inclined from normal.With the 5-Axis strategy, you can also use an inclined tool to avoid having to mill with theend of the tool tip. Use a tool offset angle [g 3-10] to make sure that the tool inclination iskept constant with respect to surface normals.Tool offset angle1 Inclination Angle2 Normal3 Tool4 SurfaceExample of a 5-Axis Planar Finishing toolpath:6.1 Lab: Planar FinishingThe goal of this lab is to show you how to implement planar finishing using related Objectives...parameters.65-Axis Planar Finishing Lab: Planar Finishing(PC) <Installation directory>: \workncxx\surface\assembly 1.

Instructions...5-Axis Parallel to Curve Lab: 5-Axis Parallel to Curve885-Axis Parallel to CurveThis toolpath is similar to "3D Drive Curve Finishing" in 3-Axis. With the 5-Axis strategy, the tool is always normal to the surface being machined. Most specific parameters are the same as in the 3-Axis strategy. However, you can impose a maximum head rotation angle.NOTEContext SurfacesYou do not need to use context surfaces with this toolpath. If a surface is in undercut along the trajectory, it will not be machined.8.1 Lab: 5-Axis Parallel to CurveThe goal of this lab is to illustrate 5-Axis Parallel to Curve Machining using related parameters.(PC) <Installation directory>: \workncxx\surface\turbine_training 1.

Instructions...5-Axis Perpendicular to Surface9Programming 5 Axis Perpendicular to Surface9 5-Axis Perpendicular to SurfaceThe "5-Axis Perpendicular to surface" strategy is used to quickly rough-machine parts made of many curved surfaces such as bumpers. Machining is made between two curves.WorkNC creates a ruled surface between both curves and creates a toolpath with respect to the normals of this surface projected on to the part.9.1 Programming 5 Axis Perpendicular toSurfaceProgramming a 5-Axis Perpendicular to Surface toolpath mainly consists in defining each of the following elements:1. two curves which will be used by WorkNC to create a ruled surface,2. the surfaces to machine,3. the stepover value,4. the maximum depth value and5. the view, which will be used to define which side you want to be machined.We are going to use the following bumper as an example:Bumper ExampleDefining two curves...It is important that you correctly define the curves that will serve as guide curves since theyare used to define the ruled surface. Normals will be oriented in accordance with this surface.If we consider our example, you could define curves on each side of the bumper. Seecurves 1 and 2 in the picture below:9 5-Axis Perpendicular to SurfaceProgramming 5 Axis Perpendicular to SurfaceDrive Curves for Perpendicular to SurfaceSurfaces to machineNow that you have defined the drive curves, you must indicate the surfaces that you want tobe machined. This is done with a surface list and surface group that you then select in theMachining zone parameters. In our example, you can select all part surfaces.Perpendicular to Surface - Surface SelectionStepover valueDefine a stepover value.5-Axis Perpendicular to Surface9Programming 5 Axis Perpendicular to SurfacePerpendicular to Surface - Stepover ValueMaximum depth valueThe maximum depth value is similar to a machining plane. It is used to avoid machining the inner part of the other side:Example: If you define a maximum depth value which is too big, you will obtain the following:Perpendicular to Surface - Maximum DepthAs you can see the tool machines the opposite side of the part.Machining ViewDefine a view which is above the part and covers all surfaces to machine:9 5-Axis Perpendicular to SurfaceProgramming 5 Axis Perpendicular to SurfacePerpendicular to Surface - Machining ViewThe final result should look like the following:Perpendicular to Surface - Final Result5-Axis Normal to SurfaceProgramming 5 Axis Perpendicular to Surface10105-Axis Normal to SurfaceThis toolpath is generally used for engraving and is similar to the 3-Axis toolpath On-Curve Engraving. It has the advantage that the tool position is always normal to the surfaces being machined or some angle inclined from normal to surface. No matter the surface inclination, the depth of the groove is kept constant.Curves to machine are prepared in the CAD environment of WorkNC.When defining curves in the CAD environment of WorkNC, do not forget to merge them.The inclination of the tool against the normals of the surface is defined by the forward offset angle:105-Axis Normal to Surface Lab: Normal to Surface5-Axis Normal to Surface: Forward Offset AngleSee Also...• Selection of the change of direction in corners [g 3-8] • Tool Offset Angle [g 3-10]10.1 Lab: Normal to SurfaceThe goal of this lab is to illustrate 5-Axis Normal to Surface Machining using related parameters.(PC) <Installation directory>: \workncxx\surface\5_axis_training 1.

Instructions...Grooves 11 11 GroovesThis toolpath is designed to machine complex grooves that are not accessible in 3-Axis. The cutter is always normal to the surface at the bottom of the groove and requires one or twocurves to define the groove. This strategy can be used to rough and finish grooves. It isparticularly adapted to machine door or window rubber profiles.You can machine grooves with a constant or variable width. Use the specific parameters todefine the groove to machine.11 GroovesGroove DefinitionGrooves11Open groove example1: Guide curveOne single curve is enough to machine this groove. It must be defined at the bottom of the wall. You must also indicate the width of the groove.NOTEWidth of the grooveIn this case, you can indicate a groove width that is higher than the theoretical width forthe tool to go beyond the part.Closed groove example5-Axis Profiling5-Axis Profile: Surface Contact Detection12125-Axis ProfilingThe Profile strategy is especially useful for part trimming. This toolpath may be redundant with rolling. Use it for trimming when you do not have any side surface on which you can use rolling.Here, Rolling is possible...Here, only Profiling is possible...Surface to machineProfile to machineIt machines with the tool normal to the selected surface and tangent to the curve which itfollows.5-Axis Profile Toolpath1 Curve to Machine2 Selected Surface3 Tool Offset DistanceSee Also...• Selection of the change of direction in corners [g 3-8]12.1 5-Axis Profile: Surface Contact DetectionWith this option, you can machine tangent to a curve and normal to bottom surface while detecting contact with neighboring surfaces.Automatic surface limitation detectionIntroduction Benefits125-Axis Profiling5-Axis Profile: Surface Contact DetectionThis parameter allows you to define a curve to machine which is ‘hidden’ by an overlayed surface in the Z axis of the View or the Machining Zone. If the perpendicular distance in the Z axis between the edge of the overlayed surface and the curve is less than or equal to the defined value then machining will be performed along the edge of the overlayed surface. The following examples illustrate how this parameter works.Surface Group, Surface Guide and Curve to Machine Definitions1 Curve to machine2+3 Surface selected for machining and as the Guide Surface 4 Inclined surface which ‘hides’ the curveNOTECurve to MachineIn order to orientate the cutter correctly, the Curve to Machine must always be on the Guide Surface.In the following example the Detection Width is set to 0.Toolpath with Detection Width Value = 0The toolpath is generated along the curve where the walls are vertical as the cutter can ‘see’ the curve. However, no trajectory is generated parallel the curve where inclined, overlaying surfaces are located.The next example shows the toolpath with the Detection Width set to an intermediate value.Toolpath with Insufficient Detection Width Value5-Axis Profiling Lab: Profiling12In this case the toolpath trajectory partially machines parallel to the curve ‘hidden’ by the inclined surfaces. The whole section of the curve ‘hidden’ by the inclined surfaces is not machined because the Detection Width value is too small.In the following example the Detection Width value is sufficient to machine parallel to the whole section of the curve which is masked by the inclined surfaces.Toolpath with Sufficient Detection Width Value to Machine the Complete CurveZ Axis View of the ToolpathThe above screenshot shows how the cutter machines parallel to the curve and against the edge of the overlying surface.12.2 Lab: ProfilingThe goal of this lab is to illustrate Profiling using related parameters.(PC) <Installation directory>: \workncxx\surface\part_ladder 1.

ug五轴编程教程五轴编程是机器人技术中非常重要的一部分，它允许机器人在三个平面上进行运动，并且可以通过旋转来改变工具的方向。

在本教程中，我们将学习如何编写五轴编程来控制机器人的动作。

1. 建立工作坐标系在编程之前，我们需要先建立一个工作坐标系。

这个坐标系可以是机器人手臂能够操作的空间范围。

通常情况下，这个坐标系由机器人的基座、手臂和工具构成。

我们需要确定坐标系的原点，以及三个平面的方向。

2. 设定起始位置机器人需要一个起始位置来开始工作。

这个位置可以根据实际需求来设定，比如机器人手臂的位置、工具的方向等。

起始位置一般由坐标值表示，在编程中使用坐标值来设定起始位置。

3. 确定目标位置在编程中，我们通常需要指定一个目标位置，让机器人移动到这个位置。

目标位置可以是一个具体的坐标值，也可以是一个相对于起始位置的偏移量。

根据实际需求来确定目标位置。

4. 编写运动指令一旦我们确定了起始位置和目标位置，我们就可以开始编写运动指令。

这些指令告诉机器人应该如何移动，以及移动的速度和加速度。

编程语言中通常提供了一些指令来实现这些功能，比如直线插补、圆弧插补等。

5. 调试和优化编写完运动指令后，我们需要对程序进行调试和优化。

这包括检查程序中的错误，修改参数以获得更好的运动效果。

通常情况下，我们可以通过机器人模拟器来模拟程序的运行情况，并进行调试和优化。

总结：五轴编程是一项复杂而重要的任务，它允许机器人在三个平面上进行运动，并进行工具方向的调整。

五轴加工中心加工球类带凸台的编程方法
五轴加工中心在加工球类带凸台时，可以通过以下编程方法实现：
1. 定义工件坐标系：首先，需要定义工件坐标系，即球心的坐标以及球的半径等信息。

根据球心坐标和球半径，可以确定球与刀具刀尖的相对位置和距离。

2. 定义刀具坐标系：在五轴加工中心中，刀具坐标系是相对于工件坐标系的坐标系。

刀具坐标系确定了刀具在工件上的位置和姿态。

3. 切削轨迹规划：根据球的形状和凸台的形状，可以确定刀具在球表面的切削路径。

可以使用曲面加工算法来生成刀具的切削轨迹。

同时，还要考虑刀具的刀径补偿和修边等因素。

4. 编写五轴刀具路径程序：根据切削轨迹规划的结果，编写五轴刀具路径程序。

路径程序中需要包含刀具的坐标变换和切削参数等信息。

5. 模拟和调试：在编写好路径程序后，可以使用模拟软件对刀具路径进行模拟和调试。

通过模拟可以检查刀具路径是否正确，并可以预先发现潜在的干涉问题。

6. 加工实施：将调试好的路径程序加载到五轴加工中心上，进行实际的加工操作。

需要注意的是，在五轴加工中心上加工球类带凸台时，需要考虑切削力和切削热的影响，以避免对工件和刀具造成损害。

此外，还需要合理选择刀具和加工参数，以获得更好的加工效果。
