Hi! How to enable those functions?

An internal groove (Multi start point) with a big pitch is to be done on a turning center. Suppose: Length = 30 mm Helix angle = 15 degree Groove diameter = 100 so Pitch = 84.179 Width = 4 Depth = 2 Number = 10 My knowledge is so weak at appropriate tooling and method to accomplish. So please...

The image is just an example. Suppose the part is turned on both of the sides, on the second side, it is necessary to find the hole center exaclty to make the C offset coordinate = 0. I know that on a VMC machine, edge finder is used to find a hole center. But what about a lathe with C axis...

Today I tried to use automatic tool nose radius compensation (G41/G42) on a Puma 300 M lathe with Fanuc 32i control. A simple test program (Face + OD turning) by an OD turning tool like: (Rn 1.2, tip 3, in Offset/Geometry table) T0101 S300 M04 G42 G0 X-3 Z3 G1 Z0 F0.1 X10 X15 Z-5 Z-20 G40 X20...

A Doosan Puma 300M lathe machine with Fanuc 32i has 0.07 mm backlash in Z axis. By setting the value (70) in parameter 1851, nothing changes. Tried different values but the same. What could be the reasons?

As you know the first and last 2 digits of Txxxx, can have 2 different meanings based on parameters been set. I am thinking about a configuration where the first 2 digits determine Turret station number + Geometry offset. But I don't know which parameters should I change in Fanuc 32i. Now...

Looking for a way for implementing a variable spindle speed in my programs. If this machine has a built in function? Is there any other way to reach this goal?

Hi! Suddenly pressing the reset button in the middle of program run. This machine doesn't have an automatic button to revert the tap when resetting the rigid tapping in middle. How is it possible to do it? Fanuc 32i
