It would appear there are a few issues with comp and front/rear turrets. Brian has it on his to do list now, so it will get sorted.

Here is a non G42 version for you to try.

Ok, this is how I would do the first op.

Datum is on left hand end for X axis.

Y and Z axis are on indexer centre line.

Using a 1/8" end mill.

I would try it on a bit of wood or plastic first.

Material is 1.375 square or round, by length of job plus what ever length you need to clear the indexer with the head.

I think you need to re-think your machine or look at using a Fanuc 18Mi they are only 13 axis and $20000.

This is a sample of the code you will need to produce the part.


(USE TOOL OFFSET TABLE)
(SET TIP RAD TO MATCH TOOL)
(SET TIP DIRECTION TO 3)

Looking at the NC code you posted it looks like you are roughing from the wrong side, rotate the datum onto the opposite face and work from that side.

I have never found one, G50 S1000 is the normal format but G50 is scaling on Mach turn.

Give me some dimensions of the arc and part you want to cut and I will give you some sample code.

Do you work rad or dia?
