标题: 如何改后处理使直线(G1)螺旋变成圆弧(G2,G3)螺旋 [打印本页] 作者: panyantao 时间: 2007-1-27 20:17 标题: 如何改后处理使直线(G1)螺旋变成圆弧(G2,G3)螺旋 有个问题困扰了很久,我用NX3编的螺旋刀路铣圆柱生成的NC程序是直线拟合的,怎么改后处理才能以IJK圆弧的方式输出作者: panyantao 时间: 2007-1-28 16:08
怎么就没有告诉我呢作者: Liujian 时间: 2007-1-28 16:21
在后处理里,把\UGS\NX 4.0\POSTBUILD\pblib\custom_command\pb_cmd_helix.tcl添加进去在程序头调用,输出线性还是整弧,自己设置变量. The following variable deines the output mode for helical records.
#
# FULL_CIRCLE -- This mode will output a helix record for each 360
# degrees of the helix.
# QUADRANT -- This mode will output a helix record for each 90
# degrees of the helix.
# LINEAR -- This mode will output the entire helix as linear gotos.
# END_POINT -- This mode will assume the control can define an entire
# helix in a single block.
