摘要
数控机械加工较多的是孔加工(包括圆盘、环槽等),并需要使用较多种类的刀具。在数控程序编程中,孔加工CAD建模方便,但CAM加工过程定义及刀具定义的交互过程比较麻烦,因此,减少人机交互,提高编程速度,就具有实际意义。按照提高计算机在加工孔的位置和几何尺寸方面的自动处理能力为思路,经过多次模拟试验和论证,用"工艺驱动+刀具控制"的方式,解决了计算机自行决定加工工步和加工方法的问题。程序编制过程以孔加工工艺为主线,以现有的加工方法为支持,用加工工艺和方法驱动的程序过程去处理孔数据和刀具数据,并以现有的刀具优先度来控制加工方法,生成合适的数控加工代码。
In the CNC machining, the hole machining is more （including disc, ring groove, etc. ） and need to use more types of tool. When programming, a CAD modeling of drilling is convenient, hut the CAM machi- ning procedure definition and the tools definition of interaction is too much trouble, thus reducing human - computer interaction and improve programming speed, it has practical significance. Improve computer processing in accordance with the position of the hole and geometric dimensions of the automatic process- ing capacity of idea, after several simulation and verification, to solve the computer self - processing steps and machining methods by use of＂ Technology Driven ＋ Tool Control＂. Programming process use discussed in this article is based on the main line of the hole machining to support existing methods, use using the program process by machining technology and methods driven to treat the data of holes and tools, use priority of existing tools to control machining methods to generate the appropriate NC codes.
