Your help in lathe is needed

[Camdude®]

the ability to use 2 different nose radii when doing rough & finish canned cycles.

[Jeremy Grigsby]

The ability to have a different feedrate for the overlap in roughing. Usually running up the wall with an 80 deg, 3 deg relief angle tool makes stringy chips. On top of that it can run faster in that area and not have a problem. Its at the end of a cut when it moves up the length of the cut, and then leads out. I manually change them now, and on long runs of parts it saves me a little time.

You can go into the toolpath editor and change them and when you post the code it will come out just like you are looking for.

In general, toolpath editing sucks; if you ever want to make a change to your part, or you need to regenerate toolpaths it is a PITA.

The ability to modify approach length & angle on groove finish toolpath.

Lead in/out?

Sure you can edit the code in the toolpath editor, it is just a pain to have to redo it if you want any changes. It was an idea that i thoght would be possible to implement. I'm sure everyones problems could be solved if they hand wrote their own code. Thanks for the suggestion though for those that don't know about the toolpath editor.

I found an easy way to be able to program VTL's from the front of the machine. All I did is edit the post to flip G2-G3 and, set the planes to the following:

 

Gview= Top-Lathe VTL

WCS= Top

CPlane= -D+Z(TOP)

TPlane= Top

 

This way I can take the engineers toolsheet for the part, which shows the tools as how you would see them

from an operators POV and how they are loaded onto the turret, and you can program on the right side of the part in X+/D+. This makes life so much easier, but only works on VTL's with the turret to the right. I say this because we have a small VTL that has the turret on the left, so I program this like a slant bed, with the post I have set up for our slantbeds. The programmer I replaced did it like you guys do, from the back and I had a hard time grasping this, and remembering to flip the orientation of the tool in Mastercam compared to the tool sheets. Maybe this will help some of you.

[Jeremy Grigsby]

Some one may have said something similar to this, but maybe use multiple tools for the same roughing path. If you are turning a long part or something and one piece of carbide wont make it through te whole cutting path. A way to tell it to use 1 then 2 then 3 at every inch in diameter or every 4 passes. Something like that. I don't know if thats a stupid idea or not, just posting it.

Changes are a comin'.

[BBprecise]

Yeah, heard that before

[SKIR68]

What about Feature based machining and Feature based drilling???

[steveo25]

At my shop we approach and retract at Z.1 no matter what. so it would be nice to have an option where you could set a line or position to approach and retract to and it would go there no matter what the values in your tool pathes are. Also being able to control your retract in X from your last cut would be kind of nice.

[chris m]

I hear what you're saying on the approach / retract line; just key in a value for the whole job and go, probably with something to un-check if you DON'T want to use that line for a particular toolpath. You can set up operation default reference points for this, but a visible (or not) line would be cool.

 

You can use exit vectors in the lead-in/lead-out dialog to do what you asked for in your second comment, but that does it on every pass.

Why does lathe have to be such a pain?!? Why does the program need to recalculate speeds and feeds when I do something like switch coolant back on (because Mastercam shut it off for some reason before...) or renumber the tools.

 

My personal favorite is when I copied a group of operations using ONE (1) tool to a new machine group and Mastercam decided that it wanted to make a NEW tool for each of the five operations. They were the exact same tool, just five of them with a different number.

 

Why does it have to be this hard, CNC Software? Why can't lathe have the same simple functionality as mill? Why can't the simple, easy stuff be fixed?

[Sbarner]

This makes me laugh. I just got done writing that post, and decided to take the plunge and see what mastercam did for recalculating feeds and speeds. It did nothing. Nothing was changed. So why the hassle? Figure it out, CNC.

[Josh Kinney -Elite Engineering]

Don't mess with Face Ops once there created, you'll find yourself doing a dance with "No boundary points selected".......

[Sbarner]

Yes, I know this. Mastercam and I have done that dance quite a few times.

[chris m]

Does stock flip still implode if you change a first-side operation? Wonder why I'm still running V9.1SP2?

[kunfuzed]

Utilize WCS so the solid doesn't have to be moved. Multiple machines, multiple ops, one solid!

 

... please.

[K2csq7]

How about tool inspection for roughing and finishing, grooving tools are not the only kind that wear out.

[Sbarner]

Here's one that bugs me. Say you want to do any lathe toolpath. After doing the chaining or whatever, the parameter box comes up. There is a value for Max Spindle Speed. Now pick a drill or something that uses a direct RPM. Input a value for the spindle speed higher than the max. You get an error. The frustrating part is that you don't even get a chance to correct it before you have to start clicking through error messages.

 

BTW, has anyone had the joy of disabling that message then getting because every time you try to type in a speed faster than the max, it just defaults back to the max? Perhaps it's just me. I get in a hurry when adding a toolpath or editing a toolpath, and then spend a minute or two swearing and wondering what's going on.
