this is a simple handwritten prog for making a 1 inch dia boss. we wrote this in a haas controller in vocational school the other nite. it runs fine until we put a value in the t1 diameter offset. then it alarms out with end prog without cancel cutter comp?????? it seems to be cancelling ok doesn't it? ive always lifted z then went to the exact x and y im currently at with the g40. T1M6 S1000 M03 G00X-1.Y1. G43H1Z.1 G01Z-.5F20. G41D1Y.5 X0 G02X0Y.5J-.5 G01X1. G00Z2. G40X1.Y.5 M30

thanks, ive never use the misc value page in lathe.ive used it for sub repeats in mill though.ill give the g30 a try.

I think g28 will send it all the way home regardless of if there is a value or not after it.

this is on a haas toolroom lathe. I rarely ever want it to go all the way home in z so I usually modify the code mc outputs to goo x 8. z 5. or something close to this. I was hoping I could just create a point on my screen and click it when I define user defined home position.

I tried putting a value in the boxes but it still outputs g28 xz 0.s it the post doing this? im using the standard mplfan post.

how do I control rapid heights and feed planes?i see there is a rapid depth box but I don't want it to feed from a high retract.i want it to raise high after the cut then position and rapid down close to the next wireframe toolpath

thank you, I found some niagra cutters that came today and seem to be doing the trick.3/8 with .625 of flutes,necked down to .360 and goes to 4.1 deep.oal is 6 in

when threading the tool is set to the center of the v in the threading tool.in simulation I know exactly how far I need to go back till it hits the wall so I back off a few thou but with the tool set to the center it goes too far and hits deeply into the shoulder.i would like to set the tool just like I set it in the machine with the forward edge being "z 0". right now I have to not go back as far in mc and then change it in the mach. in the tool page it wont let me click anything but center compensation . any ideas?

any of you guys know where I can get 3/8 and 1/2 endmills with 3.75 loc? I would prefer something standard and not a special order. I would be using them to finish 4340 at about 40 Rockwell.

3865AS210-7 sample.mcx-8 disregard all but op 15. you can see I moved the geometry to the right and drove the tool from that position as I couldn't get the tool to drive on the correct side of the model

hard to believe that it took a week to get this from my standalone mc computer to here!

I have used this all along all the time since ver 9 without any issues at all.the other day while using x8 the little picture next to the field showed as a bull mill.today it showed as a ball mill and just a few min ago it showed as a chamfer tool as I would have suspected it too.whats up?

sorry I cant post the part .ill try to draw up something similar.

thanks guys . I used wireframe ruled. and dropped the geometry the width of the cutter. I thought there might be a way of driving the upper edge of the tool with one of the new fancy surfacing paths. wireframe is one of the oldest and most dependable toolpaths of all .great toolpath with 0 retacts!

its just a straight angle.im having a hard time getting any toolpath to drive correctly using the top edge of the cutter or even to drive on the underside of a surface at all.

thanks for the replies. there must be something im not seeing here. I was thinking this would just be x,a and z motion with no need for any off center or additional axis.

no its not active. it says 5 axis option not available. cant I do it without this?

I have a model of a skull and I want to cut it completely around on a rotary on a 3 axis mill. ive done this many times but ive always done this locked at 0,90,180 and 270 deg. im only swapping the y axis for the rotary but what toolpath will let me keep spinning the rotary while cutting in z and x?

i don't have to run it slow john but i always was able to slow it way down before x8.i chamfer a lot in pockets and i usually control the leadins and outs till it hits the wall and then back it off slightly. its not a problem i was just wondering why it seems to be running so fast now.

it was on turbo! unfortunately it still runs fast with it off too.

is there an adjustment to be made somewhere though?

I keep precision way up usually and I turn the speed way down but it still usually goes way too fast.if I turn precision up to the very top sometimes the screen locks up.

ok but it measures .003 different in 2 directions.still both within the minor range. the out of round tol is "0" if I had a no and go gage I bet there would not even be an issue. do you think that measuring the minor and then making a plastic impression of the area you measured ,putting it on a comparator and then adding those 3 values together would give you an accurate enough measurement to put that down as "the actual pitch dia"?

there is only the mating part which checks out to be within the class 3 fit. they took my minor dia at 2 places 90 deg apart and recorded the size. I had a couple that went .001 under the min in one direction only but ok the other direction. then they molded the thread form at the places they checked the minor at .with the thread form now in plastic putty they put it on the comparator and figured out the pitch dia by looking at the highest point on the mold and added it to the minor they found. I was wrong in my 1st post on this. there are no gages,just the mating part which is easier to measure and is within the class 3 limits.

thanks for all of the replies! several of you answered me as I was writing my last post!
