摘　　要：基于FANUC系统用户宏程序功能编程,以间歇进给方式钻削深小孔,每次啄钻深度随钻深增加而减小,可以有效地解决加工深小孔时钻头容易折断的难题,减少了刀具损耗,生产效率显著提高。经过实际生产验证,该方案能够实现以递减式进给的深孔啄钻加工,降低了刀具成本,并满足模具生产的高效性与安全性要求。Based on FANUC macros,the drilling of small-deep holes was achieved by the intermittent feeding method,the depth per drilling reduced with the depth of drilling increasing.By this process,the problem that the drill bit is broken easily when drilling the deep-holes can be solved effectively,and can reduce the wear and tear on the tool.Meanwhile the productive efficiency can be improved.
