内凹模具,就是型腔的内部尺寸大于型腔边缘尺寸的模具。本文以内凹模具的加工为例,介绍了参数化程序在模具型腔铣削中的应用,提出了使用单刃螺纹铣刀,由参数化程序中某参数变量的规律变化驱动程序相应值的改变,从而获得满足实际加工需要轮廓轨迹的一种内凹模具内腔加工方法,在实际应用中达到加工精度要求。
The female mold is the mold whose internal size is larger than the cavity edge size. In this paper, the processing of the concave mold is taken as an example, the application of the parameterized program in the mold cavity milling is introduced. The single-edge thread milling cutter is proposed to change the corresponding value of the driver program by the regular change of a parameter variable in the parameterized program, So as to obtain a concave mold inner cavity processing method that meets the actual processing needs of the profile trajectory, and reaches the processing precision requirement in practical application.
