基于Pro/E的数控编程与加工
摘要
随着计算机技术的发展,数字控制技术已经广泛应用于工业控制的各个领域,伴随着数控技术的发展,各类能够进行加工编程与仿真的软件也应运而生。本文通过Pro/E(野火4.0版本)软件,运用其强大的编程建模与仿真加工的特点,在不使用真实机床的情况下,对数控加工典型的两种零件——回转体类和凸模类零件进行编程与加工。从零件的工艺分析开始,到分别制造出毛培,再到进行编程中的各种设置:例如刀具各种参数的选择,机床各种参数的选择(进给量的确定、进给速度的确定、下刀深度的确定等等),退刀平面的设置,机床刀具加工路线轨迹的确定与选择,然后到铣削窗口建立,车削窗口建立,最后加工路线演示以及NC检测[1]。从而更好地了解数控技术及其加工,与Pro/E软件的运用。

Pro / E-based CNC programming and processing
Abstract: With the development of computer technology, digital control technology has been widely used in various fields of industrial control, along with the development of numerical control technology; all kinds of processing programming and simulation software have emerged.
Pro/E, (Wildfire version 4.0) software, using its powerful programming modeling and simulation of machining characteristics, do not use the real machine, CNC machining two parts - the rotary class and punch class Parts programming and processing. Parts of the process analysis, to, respectively, to create a hair training, and then programming a variety of settings: for example, the tool of choice of various parameters, machine choice of various parameters (feed rate determined, the feed rate to determine the knife depth to determine), retracting plane set, machine tool processing line trajectory to determine and select, and then to the milling window to establish turning the window is created, the final processing route demo and NC detection. To a better understanding of CNC technology and its processing, the use of Pro / E software.
