More lathe issues

[Thee Dragracer1951]

I have a simple lathe toolpath. It's a bore with a step at the bottom. Two dias. The tool will only rough the larger of the two.

I just had this happen the other day and my reseller told me I needed to adjust stock. I have tried that. Does not work.

WTF am I doing wrong????

got a file Jim?

But of course....

If your depth of cut for the roughing is larger than the step it could be omitting it and leaving it for the finish pass.

 

Just a thought.

That's was my thought too Ken, nope didn't help.

 

The ONLY thing I was able to come up that worked was using computer instead of control.

 

His path seemed to ignore he had a drilled hole there even though use stock was enabled, simply picking computer instead of control and the path generated as expected.

 

I would send that in Jim

I have similar problems on occasion and would start over with a new file and it would work. Must be a bug.

I'll send it in when I wake up and have my coffee in the morning. I'm officially done with my latest 84 hour week.

Where's the beer?

[kenfromlodi]

Oh you didnt mention it was an 84 hour week..

 

Thats your problem right there!!

 

J/K if you hadnt sent the file to John to look at I would have had my doubts tho.

get some R&R

I haven't seen the file but there are [2] things that I've seen result in things like this:

 

1) Select 'overlap' in your roughing options, even if you set it to "0" overlap amount [which I always do] it will change your toolpath significantly.

 

2) If your stock to remove on one step is less than the nose radius of the insert MC will ignore it sometimes, particularly with Canned toolpaths, so you may need to drill the hole smaller in MC than it really is in order to prevent this.
