Thanks a lot for all, my friends. Very good suggestions for this problem. I always use 90 degree facemill for doing contour path before using endmill. This is saying endmill and saving time. Just like using a 1'' cylinder to cut a rectangle, 0.38''*0.8'', it is fast way to cut by facemill, especially using for 303/304 stainless steel. Anyway. Thanks again.

Hello, everyone. I am using mastercam for a while. When I tried to use a 90degree facemill to do a contour toolpath, but mastercam tool library only offers 45degree facemill, I tried to modify to 90degree facemill, but it does not accept, always say wrong. How can I create a 90degree facemill? Please help me of this problem. Thanks for your suggestions.

Thanks, my friend. I already delete the lines related with that problem, it works. Yes, the other way is to use '#" to make that line be a comment. Anyway, thanks for your suggestion.

Colin G. My friend. you are so smart. I checked my NC code. Before tool change there is the sequence number which is same with Tool number. I do not know how to upload my post. Just paste some of post which are related with tool change. Please help me check and find where I am wrong. Thanks a lot. ----------------------------------------------------------------------- # Tool Comment / Manual Entry Section # -------------------------------------------------------------------------- ptoolcomment #Comment for tool tnote = t$ toffnote = tloffno$ tlngnote = tlngno$ pbld, n$, "(", pstrtool, *tnote, *toffnote, *tlngnote, *tldia$, ")", e$ pstrtool #Comment for tool if strtool$ <> sblank, [ strtool$ = ucase(strtool$) pbld, n$, *strtool$, " " ] pcomment$ #Comment from manual entry scomm$ = ucase (scomm$) if gcode$ = 1007, "(", scomm$, ")",e$ else, pbld, n$, "(", scomm$, ")", e$ # -------------------------------------------------------------------------- # Start of File and Toolchange Setup # -------------------------------------------------------------------------- psof0$ #Start of file for tool zero psof$ psof$ #Start of file for non-zero tool number pcuttype toolchng = one if ntools$ = one, [ #skip single tool outputs, stagetool must be on stagetool = m_one !next_tool$ ] if progno$ = zero, progno$ = one sav_progno = progno$ *progno$, "(PROGRAM - ", sprogname$, ")", e$ pbld, n$, "(DATE - ", date$, " TIME - ", time$, ")", e$ *tseqno, e$ --------------------------------------------------------------delete this line? pbld, n$, *smetric, e$ pbld, n$, "G0", sgplane, "G40", pg49, "G80", "G90", *sgfeed, "G98", e$ sav_absinc = absinc$ absinc$ = one prefreturn absinc$ = sav_absinc if mi1$ <= one, pfbld, n$, "G92", *xh$, *yh$, *zh$, e$ pcom_moveb c_mmlt$ #Multiple tool subprogram call ptoolcomment comment$ pcan if stagetool = zero, pbld, n$, *t$, "M6", e$ if stagetool = one, [ if r2100bitde, pbld, n$, *t$, "M6", e$ else, pbld, n$, *t$, *next_tool$, "M6", e$ ] pindex if mi1$ > one, absinc$ = zero pcan1, pbld, n$, *sgcode, pwcs, *sgabsinc, pfxout, pfyout, pfcout, *speed, *spindle, pgear, strcantext, e$ if stagetool = one & r2100bitde, pbld, n$, *next_tool$, e$ pbld, n$, "G43", ptlngno, pfzout, scoolant, e$ absinc$ = sav_absinc pcom_movea toolchng = zero c_msng$ #Single tool subprogram call ptlchg0$ #Call from NCI null tool change (tool number repeats) pcuttype pcom_moveb c_mmlt$ #Multiple tool subprogram call comment$ pcan pbld, n$, sgplane, e$ pspindchng pbld, n$, scoolant, e$ if mi1$ > one & workofs$ <> prv_workofs$, [ sav_absinc = absinc$ absinc$ = zero pbld, n$, pwcs, sgabsinc, pfxout, pfyout, pfzout, pfcout, e$ pe_inc_calc ps_inc_calc absinc$ = sav_absinc ] if cuttype = zero, ppos_cax_lin if gcode$ = one, plinout else, prapidout pcom_movea c_msng$ #Single tool subprogram call ptlchg$ #Tool change pcuttype toolchng = two pbld, n$, "M01", e$ *tseqno, e$ pbld, n$, "G0", sgplane, "G40", pg49, "G80", "G90", *sgfeed, "G98", e$ sav_absinc = absinc$ absinc$ = one prefreturn absinc$ = sav_absinc if mi1$ = one, pfbld, n$, "G92", *xh$, *yh$, *zh$, e$ pcom_moveb c_mmlt$ #Multiple tool subprogram call ptoolcomment comment$ pcan if stagetool = zero, pbld, n$, *t$, "M6", e$ if stagetool = one, [ if r2100bitde, pbld, n$, *t$, "M6", e$ else, pbld, n$, *t$, *next_tool$, "M6", e$ ] pindex sav_absinc = absinc$ if mi1$ > one, absinc$ = zero pcan1, pbld, n$, *sgcode, pwcs, *sgabsinc, pfxout, pfyout, pfzout, pfcout, *speed, *spindle, pgear, strcantext, e$ if stagetool = one & r2100bitde, pbld, n$, *next_tool$, e$ pbld, n$, "G43", ptlngno, pfzout, scoolant, e$ absinc$ = sav_absinc pcom_movea toolchng = zero c_msng$ #Single tool subprogram call pretract #End of tool path, toolchange sav_absinc = absinc$ absinc$ = one sav_coolant = coolant$ coolant$ = zero cc_pos$ = zero gcode$ = zero pbld, n$, scoolant, e$ pbld, n$, sccomp, *sm05, psub_end_mny, e$ if f93bit3, pbld, n$, sccomp, pg49, e$ prefreturn if rot_on_x, pbld, n$, *sgcode, *sg28, protretinc, e$ absinc$ = sav_absinc coolant$ = sav_coolant

Hell, everyone. I am a starter on mastercam post file editing. I updated Mazak Post file from V9 to X5, and redefined control and machine file. Most of CNC code created by these new files look right, but the sequence number has problem. please see the red mark. ---------------------------------------------------------------- N100 (DATE - 02-07-15 TIME - 20:04 ) N20 N110 G20 N120 G0 G40 G80 G90 G94 G98 N130 G0 G28 G91 Z0.
