CNC控制加工复杂三维形体的几点考虑

Some Points on CNC Controlled Machining of Complex 3-D Shapes

论述了复杂三维形体切削加工中ＣＮＣ控制的数据接口、几何处理、加速度控制、可干预性几个问题。正确处理这些问题对保证ＣＡＤ／ＣＡＭ系统信息流通可靠、提高产品的加工质量具有重要意义。

More and more workpiecec with complexshapes,especially with complex space curves, are finished in a CAD/CAM system and reliability of information flow in the system is very important for quality ofmachined workpieces.So that correctly processing ofthe data interface,geometric processing,accelerationcontrol and controllability in the CNC controlled machining is of great importance to guarantee reliable information flow in CAD/CAM system and to improvequality'of the workpieces machining.
