I have a Mori MV-Jr can the Control helical interpolate? If so what option do I need and how do I turn it on? Any help would be great Thanx

As well as the option, you need an encoder on the spindle.

Thanx Al I guess no thread milling on this machine for the time being. Do you have any info on manuals for the 10m control. I have the Mori manuals be they are quite limited.

You dont need a spindle encoder for Helical. Need one for rigid tapping. Will look up option parameter later.

Thanx Terry if I can thread mill on this thing it's going to save me a lot of time on a job I'm running. If there are any other options available for this control I sure would like to have them. Tim

Helical interpolation lets you make a G02/G02 circular move in the X-Y plane while moving the Z axis at the same time.

The option parameter for this is 9100, bit #2 (the third bit from the right) These option parameters have to be entered in Hexadecimal using a special procedure. For info on how to enter it, tell us what your parameter 9100 is now (all 8 bits) and we'll reply with the instructions to add that one bit.

Hey Dan

That is all that is needed for thread milling on a fanuc 10m modal a control. Can you post a sample thread mill program so we could try is.


Thanks

Dan the parameters in 9100 are as follows. 00000111. as for a sample program for thread milling it's real simple.

3/4-10 thread mill program using a 3/8 dia cutter.
MICRO100 makes a real nice economical thread mill cutter that looks like a keyseat cutter. There are more expensive cutters on the market that will cut the entire length of the thread in 2 revolutions. But at $250 each they are a little cost prohibitive. The feeds here are just samples the speed and feed will depend on what material you are cutting.
