i just tryed the above "solution", turns out it doesnt work.. My machine will only handle the below listed commands: PSELECT IF GOTO VSET END So appearantly it doesnt work..

superman, will the rename command write over a pre-existing done.min, or will i have to manually delete it for the rename to work? its definitely a solution for my problem, thank you so much! by the way, where do you find more indepth descriptions for the sdf commands and functions? kyle, i dont use the tool life management, since i regularely switch between different steel alloys, cast iron and so on. I havent studied the function at all, witch is probably the real reason why its not used.. :/

yes please to prevent it from loading the same serial number engraving more than once. something like: pselect serial.min pdelete serial.min end

Im using SDF files to load a bunch of .min-files and the last operation is engraving serial number. This works great, with one little exeption, human error.. i sometimes forget to post the serial min-file between pieces, making two pieces with the same serial. So i wonder, is it possible to delete the engraving file after ive used it, so the machine stops with an error instead of engrave the wrong serial? there is VERY limited documentation regarding the .sdf in the manuals, so i ask here since you guys managed to solve pretty much all my previous problems.. i know, this has nothing to do with mastercam.. a off topic question regarding mastercam tho.. i use a simple tool change program to check the tools for wear between runs (a few times a day). The nc-file is simple, close door, load a tool, go to x60 z600 (clear of chuck, but low enough to easily check the tool), open door, then op stop (m01) and repeat with next tool. But this i have to write manually for every tool in the project. So i wonder, is it possible for mastercam to post only the tool changes and not the whole operations?

A update we managed to solve this issue by drasticly increasing RPM and use smaller inserts. The multus dropped aprox 20 rpm for the first full and a half rotation just when the tool got contact with the work piece. and appearantly 5mm insert, 120rpm and 0.05mm cutting depth is too much for this machine. Now i use 260rpm, 4mm insert and 0.1mm (course) and 0.05 (fine). So the problem turned out to be the multus, that it doesnt detect and compensate the dropped rpm fast enough.. A bit of a bummer on a machine this expencive, bought specificly to handle thease types of jobs.. But at least i found a work-around Thank you guys for your help

M866 turns ON the cas M867 turns it off. I usually turn it off when interpolating or with alot of tiny movements, since it slows down the machine movement dramaticly and results in chipped inserts. What would P code 3 do?

I cut in M602, and use the lower corner when offset setting. The picture displays the tool in M603 merely to display the insert. The P column shows "0" for that specific tools, as for most other tools in my register. Auto calc got me confused, i dont know what youre talking about.. :/ I dont use M321 for tool change, instead i use M360, witch was programmed for my by the sales tech on-site. Here you go: N1001 G50 S120 N1002 M90 N1003 G20 HP=1 (HOME POSITION) N1004 MT=02301 N1005 M360 G0 X9999. N1006M24 N1007M866 N1008G97 G95 G52 S120 M41 M602 BA=0.

The tool is mounted upside down on the photo compared to when its in use (this to show the insert on photo)

Here´s my program line: G72 X176. Z24.75 B00 H5.25 D.05 W.05 F10.16 M32 M74 The tool is for face grooves, with correct radius for clearance. Im not sure what you mean with "above center height", but my tool insert is below the spindle center if that has anything to do with it.. Do you guys want pictures?

Ive been trying to solve this problem for months now, and i simply cannot get my head around it. I know, its not mastercam related, but i have no where else to go.. Im cutting a spiral groove on the face of the chuck, using G72 and alter the start/stop points in mastercam to get the groove wider than the tool. But the groove isnt uniformly wide from start to bottom. Im using relatively low rpm (120) and only 0,05mm cut depth at a time (5mm wide insert) On other spiral wheels (we make manual chucks), the start (outermost) of the groove is generally tighter the first half turn, then gets wider and keeps same width the rest of the way. But now i get the opposite error, wider at the start. I belive i checked everything, even painted my insert holder to check if it would scratch against the groove wall, but paint stays unaffected after a full cycle. So i ask, beg and pleed with you guys, could anyone please help me solve this? im clueless and management thinks its an operator issue..
