现在给大家分享一下，孔铣命令宏后处理制作方法，只说方法教程，请见谅！
1.新建一个后处理
2.在N/C数据定义模块 →文字 →找到“Z”
3.右键→创建“Z_1”
4.新建选择“文本”格式
5.在N/C数据定义模块 →块 →找到“circular_move”
6.右键→创建“circular_move_1”右键→创建→“circular_move_helix”
7.删除“circular_move_1”中的“Z”并添加“Z-1”表达式“#26”
8.删除“circular_move_helix”中的“Z”并添加“Z-1”表达式“#18”
9.在 程序和刀轨 模块→定制命令→导入→在文件夹中选择“pb_cmd_helix.tcl”
10.在 程序和刀轨 模块→程序→程序起始序列→添加块右侧选择“PB-CMD-init_helix”→添加块→“%”后即可
11.在 程序和刀轨 模块→定制命令→选择“pb_cmd_helix.tcl”用下面代码替换原代码
12.保存后处理文件，好了，来试一下你的宏程序后处理吧 uplevel #0 {
#
# This ommand will be executed automatically at the start of program and
# anytime it is loaded as a slave post of a linked post.
#
# This procedure can be used to enable your post to output helix.
# You can choose from the following options to format the circle
# block template to output the helix parameters.
#
set mom_sys_helix_pitch_type "rise_revolution"
#
# The default setting for mom_sys_helix_pitch_type is "rise_radian".
# This is the most common. Other choices are:
#
# "rise_radian" Measures the rise over one radian.
# "rise_revolution" Measures the rise over 360 degrees.
# "none" Will suppress the output of pitch.
# "other" Allows you to calculate the pitch
# using your own formula.
#
# This custom command uses the block template circular_move to output
# the helix block. If your post uses a block template with a different
# name, you must edit the line that outputs the helix block.
#
# 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.
