DIN 76-B标准是德国工业标准，主要用于规范退刀槽的尺寸。

退刀槽是机械加工和模具制造中的一个重要概念，它是指在刀具加工过程中，为避免刀具与工件或夹具发生干涉而在刀具上设置的一种槽。

退刀槽的尺寸对于机械加工的效率和精度至关重要。

根据DIN 76-B标准，退刀槽分为两种类型：圆形退刀槽和方形退刀槽。

圆形退刀槽的尺寸计算公式为：退刀槽直径= 刀具直径+ 2 × 退刀距离。

方形退刀槽的尺寸计算公式为：退刀槽宽度= 刀具厚度+ 2 × 退刀距离。

退刀槽的深度一般为刀具厚度的1/3。

退刀槽尺寸的选择主要取决于刀具的类型、加工材料、加工工艺和机床性能。

选择合适的退刀槽尺寸可以提高刀具的使用寿命，降低刀具的磨损，提高机械加工的精度和效率。

退刀槽在机械加工和模具制造中有着广泛的应用。

在机械加工中，退刀槽可以避免刀具与工件或夹具发生干涉，从而提高刀具的使用寿命和加工精度。

在模具制造中，退刀槽可以提高模具的制造精度和使用寿命，降低模具的维修成本。

总之，DIN 76-B标准退刀槽尺寸对于机械加工和模具制造具有重要意义。

目前，数控铣床和镗铣加工中心使用最多的仍是7∶24工具锥柄。

但在高速加工机床上，1∶10空心短锥柄的使用正日益增多。

对于车削中心和车铣中心，则以1∶10短锥柄使用较多（车削中心使用的CZG圆柱柄工具系统不属本文讨论范围）。

自动换刀机床常用的7∶24工具锥柄标准主要有：中国国家标准GB 10944－89“自动换刀机床用7∶24圆锥工具柄部40、45和50号圆锥柄”；国际标准ISO 7388/1：1983（40、45和50号工具锥柄）和ISO 7388/3：1986（30号工具锥柄）；德国标准分DIN 69871－1：1995（30、40、45、50和60号工具锥柄）和DIN 69871－2（40、45、50、55和60号工具锥柄）两种；日本现行标准为JIS B 6339：1998（30、35、40、45、50、55和60号工具锥柄），用于代替日本工作机械工业会标准MAS－403：1975（40、45、50和60号工具锥柄）；美国现行标准为AMSE B5.50－1994（30、40、45、50和60号工具锥柄），用于代替ANSI/AMSE B5.50－1985标准。

手动换刀用7∶24工具锥柄的常见标准有国家标准GB 3837.3－83和国际标准ISO 297－82，以及机械行业标准JB 3381.1－83。

1∶10空心工具锥柄目前已有国家标准GB 19449.1－2004“带有法兰接触面的空心圆锥接口第1部分：柄部—尺寸”。

它等同采用了国际标准ISO 12164－1：2001的内容。

原德国标准DIN 69893－1：1996已被新的标准DIN 69873－1：2003代替，新的德国标准也等同采用了国际标准ISO 12164－1：2001的内容。

其它常见结构的1∶10工具锥柄基本采用企业标准，具有垄断性，如美国肯纳公司的KM型系列、瑞典山特维克公司的Capto系列、德国瓦尔特公司的NOVEX系列等。

自动换刀机床用7∶24工具锥柄的中国国家标准GB 10944－89是参照采用国际标准ISO 7388/1：1983制定的，除对极个别项目数据进行了圆整（如尾部螺纹底孔深度13）或未规定数据（如法兰上的键槽根底倒角）外，其它数据完全相同。
