OUR MAIN MAN MIRR0RED THE PART IN THE MACHUNE AND SO FAR SO GOOD. STAY TUNED. WE ARE GOING TO FIGURE OUT HOW TO PRG IT ALSO USING MIRROR THANKS

using 4 axis rotary you do not have that option with surfaces

I used rotary 4 axis and picked the surfaces to drive the tool. I programmed it with the 4 axis holding the part on the left side machining right to left on x axis of rotation. I loaded the pgm into the cnc and no problem on graphic run till I realized the 4 axis is setup for left to right cut. i guess we can just setup the 4 axis like it is programmed. I rotated the part 180 in mastercam 9.1 and regenerated the toolpaths so we could use the setup we had. When doing a backplot or verify the toolpath still machines right to left. I can't figure out why I can't get the tool to run from the start point left to right.

THIS A ROTARY 4 AXIS CUT. I'M SUFACING A ROD.

hEY GYTS, I PROGRAMMED MY PARTS TOOLPATH GOING X POSITIVE TO X NEGATIVE CUTS. AXIS OF ROTATION IS ON X. THE CUT IS FINE THIS WAY. BUT I HAD TO ROTATE THE PARTS 180 DEGREES AND REGENERATE DUE TO THE 4TH AXIS IS SET UP THE OPPOSITE DIRECTION. THE TOOLPATH HAS A START POINT BUT IT IS CUTTING INSIDE TO OUTSIDE INSTEAD OF FROM START POINT OUTSIDE TO INSIDE. IS THERE A SETTING FOR X SOMEWHERE. I NEED -X TO POSITIVE X CUT. THANKS

88matt i sent you a message

Hey guys, Well I have 30 parts with 30 different surfaces at the end of rods. Dental job. The ends of the rods kinda look like your mollers in your mouth. different shapes. Anyway I created a check surface in the middle of the diameter so i can surface machine 1/2 at a time. Rotate 180 and do the other side. This is the way they said they have done before. Its a bitch splitting the profile has to make sure there are no under cuts. Do you think it would be easier to rotate the part while it is machining 360 degrees and do all the surfaces at once. Any help would be appreciated. I have the file if any one is interested at looking at it. thanks

no threadmilling experience. ;o(

tim , i am confused on identifying the tool pitch 56 diam. 1. ????? thanks

the cnc lathes are backed up and he wants to do the threading on the other side when we face to size. it will be going .5 deep thread. thanks,

Hi guys, Never did this before. Can anyone lay me out on threading a 1 inch 56 into brass. The boss does not wantt o do in the cnc lathes. What tool should I order ? Thanks

Hey guys, I programmed a part in MM and the tools etc. But I need to convert everything to english due to the operators will have a hec of a time. Can I convert or do I have to reprogram the part in English. Thanks,

hello friends. I was trying to drill using rotary. 15 degrees 24 times on a can. I had parames set at z axis rotation and 15 degrees max and min created the holes with points and a line. I selected hole centers and used line. got the first drill cycle to work but no rotation. any tips thanks

how slow. I am using the 1/8 inch cutter just for the final pass on the outside contour .01 . Everything else is finished. i used a 3/16 prior to the 1/8 thanks,

I'm having a hell of a time with chatter in the corner redius. It is .0625 and my finish cut is with a .125 2 flute in aluminum. I have tried different speeds and feeds byt no luck. The place i work uses 4 flutes alot. i never used 4 flutes on aluminum. The operator loaded a 1/2 inch 4 flute for a part i programmed . I had a pocket routine and he wondered why the cutter broke. Well you can't use a 4 flute when you are going 50 ipm and 7000 rpm. I has to set up the job abd run today. The operator has 4 flutes everywhere. I put in 2 flute carbide and ran the part no problem. He also had long length cutters Snap crackle pop. Chatter city. Everything is okay except the radius in the corners. Anyone got any ideas. i could run the damn thing slow and get a GOOD FINISH in the radius BUT JOB SHOPS DON'T LIKE THAT TO MUCH. I WAS RUNNING 13 IPM AND 7500 RPM. JUST SO the cutter would not snap. .550 deep. .125 depth cuts.

jmparis good point. I have dealt with alot of mechanical Designers who have never been in a machine shop or took any classes. They design the part and I tell them we can't do square corners or a .030 radius in the corner 2 inches deep. So they adjust to a larger radius diameter. also on surfacing a 1/8 cut along the surface might be one page of code. I have friends that have been programming and machining for many more years then me. These guys tell me they don't screw with the code at all unless they have to. And these are pretty trick parts. They are also tranfroming the geomtry and programming mutilple parts on 3 vises just using G54. This is what I do. You can tranform the geometry and mill all 6 parts with the first tool and drill all with next too and so on. When you tranform the toolpaths your first part is machined complets for first article then the next parts I machine by operation has stated above. cutter comp can be used also both ways for wear.

haas_guy AMEN!! I worked recently with 2 engineers one fresh out of college. They took the gcode class. Thought their crap did not stink. They did things I never seen before. CRASH!!! I program and machine the part. I'm not the greatest around. But I do have common sense. My point is in all the years of machining and programming 1000's of parts very rarely do I mess with the CODE. Sure Z now and then and wear. Damn let the cam system do the work. My parts are within tolerance that is all that counts.

Hey guys, I know there are 10 ways to skin a cat in machining. Every machinist/programmer my do the same job different. I don't know G-codes very well. I took the g-code class, and took all the advanced 2D and 3D classes Mastercam offered a few years ago. I also did mucho surfacing at my last job. Making fixture nests for cell phones ,assembly fixtures, testing fixtures and DVT fixtures. 3D Prototype models with surfaces etc....I was thrown into the frying pan. Had to learn a lot of Mastercam on my own while trying to get jobs done for the engineers. When I watch the code scroll on the controller while the part is running I know what is going on and why. Recently I have dealt with some so called hotshots who took a gcode class and thought they were IT. I see them writing code or adjusting code and ramming a 1 inch end mill 2 inches deep into the part. Melting the aliuminum and it looks like they were welding. Mistake after mistake. I let the cam system do the work. I program the model and let it rip. I have seen things happen recently that I have never seen in my 20 plus years. Hotshots making a wrong z move or something else by writing or adjusting the code. Just adjust your fricking program and resend the file. Damn!!! use VERICHECK before you send the file. Wasting their time debugging their crap and I have 3 more parts programmed. I watch the Z move real close on 2D. 3D surfacing is no brainer on Z. Mastercam offers eveything you need to do the job without standing their and wondering why you just scraped a part with your screwed up code!!! Another thing. I know there is more control on a cnc lathe when boring a precision hole -+.0003 with a boring bar. But for petes sake if your ID is .300 to .3005 buy a reamer at the high of tolerance and it will wear down to the low sooner or later. Boring 500 parts and your constantley adjusting the cutter comp on the controller to make sure the go and no go gauge fits. then again most shops are cheap and they want you to bore a hole 6 inches deep and hold concentricity to .0002 end to end. With what ever tool is around. leave .003 and Hone the bitch gasp!!! What do you think?

hello friends, seeing how I am working in a production shop now. We use cutter comp a lot. I have not had much experience with it due to I just adjusted the tool diameter on the pgm and resend the pgm for wear. Should I use cutter comp in control? or wear? I will be adjusting cutter comp on the haas controller. What is the difference? Thanks in advance.

can't you just make the ops a subroutine somewhere

heres the senerio 3 vises. 3 offsets -G54-G55-G56 op1 is face op2 is chamfer op3 is drill Can someone tell how to set this up so the 3 ops are done for all 3 vises. I usually tranform on a plate multiple parts. Now I have to use 3 vises. Never done before. Any help would be appreciated. Its no problem setting the offsets on the machine. Do you have to group?
