Mulitiple parts on lathe

[Anonymous]

I trying to machine the same part multiple times out of one piece of stock. I only have one WCS and cannot incrementally change my work offset. I was hoping that I could generate toolpaths for one part and somehow copy these toolpaths multiple times so they would machine multiple parts out of one piece of stock. I’m not sure how to go about this other than manually generating  tool paths for each individual part which would be a long process

. Hope this makes sense

Try using a Linear Pattern in the Z direction. The New Pattern option is on the Setup section of the toolbar.

I think this will work but I just can’t get it to do what I want. At the moment, the simulation just keeps doing the same thing over and over at the same position in Z axis. When I output the program it just produces one part. I'm doing something wrong but not sure what

Got it working and its exactly what I want.

Thanks

When using liner pattern on the lathe this is the error I get. Naturally you cant really do cut-off parts in a positive Z axis direction. Fusion is reading the path as you can see, but will not allow me to implement it. I would like to do multiple parts, not imaginary parts. How might I make this work?

You can't input negative values. Input positive values and click "Reverse Direction"

That reversed the order of tools I believe. "Flip" however helped me achieve what is desirable, aside from the fact I will have to treat -.252 as zero.

Linear pattern will post main program for each new part with Z values shifted in absolute coordinate, could get pretty long and confusing.

If there is a memory limit in machine control you can do the following.

Program one part and make it sub routine, use G10 at the top of part program to shift G54 by desired value each time program runs.

Run main program to repeat as many times as desired.

%

O0001 (Main program)

(call part program, loop 10 times then stop)

M98 P2 L10

M30

%

%

O0002(part program)

G10 L2 P1 W-.25 (shift G54 in Z minus direction by .25 each time program runs)

(part program here)

M99

%

Downside is that if you have to reset the process, machine loses count of loops so you have to be careful.

After the loop is complete,  start new loop by resetting G54 to original value and extending stock to starting length from chuck.

Make another set of parts using same scheme.

This needs some attention or it will lead to crash if you set stock for new group of parts but forget to reset G54.

If you know insert is not going to make it on next part, finish that part then reset process, index insert, set G54 to original value, set stock to start position and continue.

Unfortunately, our lathes implement work shift as opposed to work offset. Your advise is appreciated no less.

Make your program for 1x part, then call it as a subprogram at different Z locations?
