深孔数控加工自动编程技术的研究

Automatic programming technology for NC machining of deep holes

对数控深孔加工工艺及编程技术进行研究,并在基于UG软件二次开发平台上,利用VC++编程语言开发了深孔钻3D自动编程系统。成功地将数控深孔机床传统加工的看图取数、手工编程的方式,转变为直接从3D模型自动取数编程。实现自动获取孔的位置参数、加工深度,自动对不同直径的孔进行排序,解决了深孔加工在交叉贯穿过孔无法实现自动变速的难题。在不占用机床加工时间状态下自动生成加工程序,从而达到加工参数的准确性,避免2D数据和3D图档不一致和操作失误造成的加工出错导致的经济损失。有效提高机床使用率和编程效率,节约加工成本。

Based on research on NC deep hole machining and programming technology and second development platform of UG, a 3D automatic programming system for deep hole drilling was developed by using VC＋＋. The traditional programming model was successfully transformed to automatic accessing and programming with the system. The automatic acquisition of location parameters and machining depth, and the sequencing of different diameters of holes were realized, thus the automatic transmission was achieved.
