Can someone try something in Contour for me??

[crazy^millman]

Make a line. Then do a contour toolpath using computer comp. On your lead it and lead outs put a number. Then on your radius swing put 1 degree and back plot. Save the back plot to a level and then change to 2 deg and then back plot and compare and tell me if you see the toolpath starting on the line not using the lead in and out for 1 deg and then using it for anything other than 1 deg. I just about scrapped some parts today if I had not taken the time to verify if was leading in and out like I wanted.

 

Thanks.

1 deg no lead in /out

2 deg works

i used .2 for line lead in/out .2 for rad

[Hardmill]

I did it and all looks like it should.

 

 

PEACE

[Hardmill]

I saved both backplots and analyised entities

all they are correct.

1 deg didn't work here either.

I used .5 deg, 1 deg, 2 deg, 3 deg.

All produced the same path,

.500 Lead in Length didn't work

.625 length worked with both angles

Works just fine here.

 

Have you tried changing the radius or length of the line?

 

Maybe i could recreate it better if i knew your perameters?

 

Tool dia:?

Line length:?

Arc radius:?

 

and I'll try it again.

Does not matter the tool does not matter the length. I can see it on 5 different computers with many different programs.

Appears to work as expected for me.

system tolerances?

[crazy^millman]

Ok here is how to repeat this with any tool. Make the angle 1 deg. Then make the radius length less than half the tool. No matter what tool you use you will see it happen with 1 deg. Now change it to 2 deg and it will do just fine. It does not matter if you use wear, control, or computer it will do it everytime again no matter the cutter.

 

So use 1/2 endmill. Use any line. Then use any length for the lead in and out for line. Then on the radius make the length less that 1/2 the cutter. Then use 1 deg and look at the backplot. Then use 2 deg and look at the backplot and see if there is a difference. Again I can do this with any size cutter on 5 different computers.

 

Standard Tolerances that load with Mastercam.

 

I put a file on the FTP called LEAD_1DEG_PROBLEM.MCX in the MX2 folder. Same toolpath just the 1st one has one deg and the 2nd operation has 2 deg and you can see what I am talking about. I made the 2nd operation at -1. so you could see it in ISO. You can change it to 0 like the 1st operation and it will do the same thing.

 

Thanks for the sanity check.

[Slepydremr]

It's the gouge check.

 

As soon as I un-checked that box it worked fine. I never use gouge check so that explains why you have different results than I.

I couldn't get it to work here either
