Haas lathe/mill simulator

[LatheCrasher]

This is a stand alone Haas simulator for lathe/mill. The lathe simulation is for SL-20 running in Yaznac mode. Since you don't physically touch the tools off, is it possible to set the graphics so during simulation the coordinates reflect your programmed coordinates?

Thanks!

If you want to match a machine, save a backup from it and load it into the simulator.

If you just want it to run, you can just put ballpark numbers into the offsets pages.

[LatheCrasher]

Thanks for the reply! Can you break it down for me a little more? I'm trying to think out of the box here on this. Do you mean the tool offsets from another Haas lathe. The shop lathe does not have a usb port or rs-232 com connected to it for loading programs. All programs are entered manually. We have Mastercam but no lathe cadcam.

Can you help me with setting up the graphics. When running the program in graphics on simulator I'm constantly getting "z" and "x" over travel errors. I just keep punching in numbers in the offsets page until it runs with no error. Is there another way because it has no rhyme or reason to me. For instance, turning 1" stock down to .750 and 1/2 inch back in z, I have my offsets at x,-10 and z, -8 and will receive an x over travel alarm. Running in Yasnac mode, T5 so offset would be T5500 in offsets page.

What is your shop lathe? Do you have a serial number if it's a Haas?

Yes, I mean copying the offsets from another Haas lathe.

You do not need to have tool offsets, you can get by with just work offsets.

You can also change the model in the simulator to a larger machine.

SL 20, serial #63177

Simulator serial #808026

I need to stick with Yasnac mode since the student's cirriculum is set up for Yasnac instruction. I know Haas recommends Haas mode.

Thanks again

I am not too familiar with Yasnac, what are the work coordinate options?

For Fanuc, I would put -8. in the X and -4. in the Z for the G52 and leave every other offset at 0.

If you cannot use G52, you can put the values into every offset for tools 1 through 12.

If this doesn't work, post up the min/max X/Z values in a failing program.

My next class is Tues night and I'll try your last suggestion. Just a note to add about Yasnac offsets. Yasnac uses tool shift offsets numbered 51-100. They are called with a G50.

G50 T5500 (Tool 5 with no tool nose comp)
G00 T505 (Turrent indexs to T5 and applies wear offsets)

[KenFoulks]

I know about the Yasnac tool offsets, what about the Yasnac work offsets?

[LatheCrasher]

Maybe that is the problem since I'm not using work offsets. I'm not using G52 or G54-59. When setting up the lathe to run a part, I touch off each tool in my program in the tool offsets page(51-100) and call up each offset with G50.

I've used work offsets on mills but never on a lathe. We have a Mazak Quick Turn with tool presetter but it's not working so I still have to touch off each tool.

(+) x value and (-) z value for the tool/tools in program works. Just input in tool offsets, no work offsets.

Just used to watching my numbers when proving out a program.
Thanks for the help!
