could you just make a dummy operation to drill the id out of the cylinder. and just turn posting off on it?

i guess im lucky i havnt run into that situation yet psyco. thanks for the tip

i wish incremental was as easy/obvious on a mill as it is on a lathe...

stop the machine when you need to change the drill. Cycle start from the tool call, go into single block and read the drill cycle call line only. having a K0 or L0 on the call line means that you wont drill a hole but you will load in the cycle parameters. then go into edit and cursor down to the hole you left off on, go back into memory and cycle start. I think that is what rekd was talking about.

At our shop it was mandated that all new machines brought into the shop would be in metric. So now all the old guys dont want to run the brand new equipment and the younger more open minded people get to work on some cool stuff. whats more precise .001mm or .0001in? isnt that enough reason for some? I came up using inches. After one or 2 jobs using metric i never want to go back. And thats how most of my coworkers feel once they actually go for it. I say screw all this inch fractional garbage. It almost seems like once this inch system is out of the way that a quarter of all math would be obsolete. sorry for a rant

i do something like this #100=3(HOW MANY PARTS) G0G90G54.1P1X0Y0M3S3423 G43H1Z25.4 M98P1L#100 O1 X0Y0 ; ; G0Z25.4(LAST MOVE RETRACT) G54.1P[#4012+1](CURRENT WORK OFFSET + 1) M99

Ill try and figure out how to model it right tonite at work. I dont have internet access at work so i have to bring it on home for this. So tonite i will try and have a better example. Picture the radius stopping where it is at but the cylinder goes on for another inch or so on the left side. So the radius doesnt go thru the entire length. So when i get to that end there will be a form of the endmill were i stop(?). Its ok if there is by the way.

This is just an quick drawing of the part. its actually closed at one end and why i think i need to cut it straight on and not use a saw. A flat on the end will be acceptable from an endmill (i couldnt figure out how to draw that). This is a job my shop normally wouldnt take because "we dont have anyone who can do that". So im hoping i/we can figure it out. thanks guys

I have this part to make. Im wondering if it is possible to cut it on a horizontal mill using the 4th axis? Maybe with some XZB trickery. Its a 17" radius cut into a cylinder along its axis. radius cut Im thinking i will make a fixture to hold 4 of these with the radius along the x axis. a .250 endmill and 60degree form tool for the chamfer? Im just having trouble visualizing this. thanks

same as DavidB stated but with the mazak lathe posts also.

I would like all of the above to be applied to the mplfan and other lathe posts also. Toollist and cuttercomp type being the big ones.

There is no workoffset for the indexers. We do have one HMC with a rotary and i could just workoffset the B on that one but i cant use that machine. I guess the easiest thing to get me going is the old Find/replace move. But im going to figure out a mastercam way somehow. thanks

its a mazak 640M. its not a rotary just indexing its around 20 ops total. 1 work offset per face. I am hoping i can go in and change the wcs in all the ops instead of rotating all the geometry and picking new T-planes. Im not at work now so ill have to take notes.

I came across a problem last nite. I programmed a part for one of our horizontals. its 4 ops on a kurt 8 station cluster vise. I programmed it with the parts at B0,90,180 and 270. one op at a time moving the parts along. well come to find out the only available pallet has the vises at B45,135,225,and 315. im wondering what the easiest way to correct this is? im not using the wcs for this but maybe i could rotate the wcs by 45 degrees in the top view and regenarate?

search for the postblock ptooltbable you will see whats making what come out in your code. you probably want to get rid of popnote and tldia.

draw the top of your contour. under the 2nd tab under the contour toolpath check depth cuts. there is an option for tapered walls there.

if you want to increment by say 100 everytime then go down to pheader and at the end you will see #seqno = 100 #seqinc = 100 #n = seqno take out the #

really. forcing the n, with an * should override that turn omitseq yes, then in in your post search for comment change it to this *n, comment

for the seq #s try and turn off Seq #'s. THe switch is up towards the top of the post. omitseq : yes #Omit sequence no. and try putting * in front of the n, were you want the seq number

G76 is a canned cycle

i believe you just move your thread start point in or out by half your pitch for a 2 start thread. 1/3rd for a 3 start etc. YOu can use the G76 cycle or G32 longhand. in mastercam under the last thread tab its on the top right corner.

Something along these lines? G0G90G54X0Y0M3S3000 T1M6 Z2.54M8 G66P9222F200.Z-25.4 X0Y0 X40. X80.Y20 G67 O9222(DRILL IN/FEEDOUT*3) G1Z#26F#5 Z2.54F[#5*3] M99 You can get fancier of course.

thanks mike. until we figure this out i just chained all the holes and pocketed them all. I can get the code like i want if i transform-translate but you cant make a circular pattern that way. Did you try the fadal post off the CD? Was the sub_trnzx not formated? or was it just mine.

v9.1sp2 maint. mpfadal1.pst. using subroutines the machine goes all crazy from the G68 rotations

but how do i do that in mcam
