如图所示

我的后处理里无法输出螺旋刀路，这样处理出来的程序不但大，而且在机床上走起来也不顺畅，本人对后处理的修改不是很懂，希望懂后处理的师傅能帮改一下吗，谢谢！（后处理只有两个文件，现传上)

打开你要用的后处理，TCL格式的那个，然后搜索proc PB_start_of_program 图片（1）
把PB_CMD_init_helix加在图片中的位置.

然后把这一段加在图片（2）的位置应该也行的 ，自己搞一下看看.
#=============================================================
proc PB_CMD_init_helix { } {
#=============================================================
uplevel #0 {
#
# This procedure 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_radian"  

#
# 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.

   set mom_kin_helical_arc_output_mode LINEAR

然后出来就是有R的了？

谢谢一片云兄，但是直接在网页上拷贝好像不行，（如图），能否抽时间帮我改一下，谢谢
