UG后处理圆弧输出程序太长

LISHOULONG1982 · 发表于 2010-5-18 10:46

，因为我们用的是卧式加工中心，后处理出来一个圆弧输出就要很长，很占空间。不是像G02/G03X100 I-100就可以走圆弧，而是跑好多个点。

#
# 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.

在后处理中设置螺旋下刀。

我也遇到楼主的问题了，好烦，而且输出的数值不对

ylongs · 发表于 2011-5-10 13:04

圆弧输出有问题，和螺旋下刀没什么关系吧?

以上程序机床走到红色上一行会报警

红色一行为什么会少个R值？

我用UG4.0用同样的后处理处理出来的程序有R值！

是不是ＵＧ６．０本身的问题啊？

请各位指教！

谢谢
