CA6140 车床数控改造之控制系统设计内容摘要本文主要是将传统的 CA6140 车床的电气控制系统改造成为数字控制的开环控制系统。改造后的系统是以 MCS-51 单片机系统为控制模块，以步进电机为驱动执行元件。实现 X 轴和 Z 轴的两坐标联动以及对刀具的自动选取。同时能够进行直线和圆弧的插补；工件在一次安装后，完成多道工序的加工，通过编写不同的程序完成各种较为复杂零件的加工；改造后的 CA6140 车床提高了加工范围和加工精度。关键词：CA6140 车床、控制系统、数控改造AbstractThis paper mainly is that the traditional CA6140 lathe electricity control system is Reformed the numerical control the open-loop control system. After the reform system is take the MCS-51 monolithic integrated circuit system as the control module, Take step-by-steps the electrical machinery as the actuation functional element. Realizes X axis and the Z axis two coordinates linkage as well as to the cutting tool automatic selection. At the same time can carry on the straight line and the circular arc inserts makes up; After installs the work piece Completes the multichannel working procedure the processing Completes each kind of more complex components through the compilation different procedure the processing; Enhanced the processing scope and the processing precision compared to the traditional CA6140 lathe.Keywords: CA6140 lathe Control system Numerical control Reform目 录前言........................................................5正文.......................................................101.总体改造方案构思...........................................101.1 CA6140 车床的用途.......................................101.2 CA6140 数控改造后的功能.................................101.3 普通车床数控改造设计方案................................101.3.1 改造机械部分........................................101.3.2 增加数控控制系统....................................101.4 CA6140 车床的电气...
