这是关于为在传送带型砂带磨削中获得较高尺寸精度和较长工具寿命的磨削条件的自适应控制的研究。首先,研究了残留余量,其次研究了传送带型砂带磨削中的工具(砂带),并且弄清楚了它们的一般特性。与此同时,证明了这里提出的参数h_N对于定量地评价工具磨损是一个有用的值。在此基础上制造了一台自适应控制的砂带磨床以改善工具耐用度和尺寸精度。磨削速度和工件速度由微型计算机根据参数h_N(即工具磨损)和切削深度的变化而自适应控制。结果,尺寸精度和工具耐用度同时得到改善。
This is a study on adaptive control of grinding conditions for achieving higher dimensional accuracy and longer tool life in belt-type belt grinding. First, the residual allowance was studied. Next, tools (belts) in belt-type belt grinding were studied and their general characteristics were clarified. At the same time, it is proved that the parameter h_N proposed here is a useful value for quantitative evaluation of tool wear. On this basis, an adaptive controlled belt grinder was manufactured to improve tool durability and dimensional accuracy. The grinding speed and workpiece speed are adaptively controlled by the microcomputer according to the change of parameter h_N (tool wear) and cutting depth. As a result, dimensional accuracy and tool durability are improved at the same time.
