Hitachi Seiki Hi Cell23 Interpolation Y,Z + X linear movement.

[mexcentro]

We are trying to use a Thread Mill (12mm diameter 18 threads per inch) to make a .6250-18 bore.

this is our code:

When te machine starts de operation runs into the first positions and start interpolation Y an Z but X doesn't move. I dont know how make the machine move X axis.
I hope you can help me with this issue.

Thank you.

...delete the G19's

Hello. thank you for your help.
G19 is the operation for interpolation Y and Z + a (a= linear movement for any other axis that is not on the interpolation) this case is X.

I will try deleting G19 but then do you recomend other code for replace this operation?

Again. Thank you so much.

...the Format would be something like G17G2X...Y....Z...I...J... (for Helical cut)

Are you trying to use live tooling on a lathe ?
With a thread in the X-axis?
G19 would be used.
The arc is in YZ plane (J&Ks) with pitch control in the X axis?

Normally threadmilling a R/H thread is to climb cut with a start at bottom of hole moving in CCW direction .... so the chip is not recut & is left under the cutter.

I don't see any code to start milling mode, or start the live tooling
... not sure, but are you programming 4 points for 1 pitch ?
... check that X is not doubling pitch in diameter mode. And milling mode turns X into radius values.

Can your machine interpolate in 3 axis similaniously ?
