Thought its the same for different models. Fanuc 32i-A and 21i-TB.

Hi! How to enable those functions?

Sorry, how to rotate the cutting edge of the tool? After watching the picture, you still recommend the above holder with a square groove insert?

Not a grease groove, something like this picture that the groove goes through. In this case, G76 is faster or C axis? It seems in G76 spindle may rotate in more RPM, so the time is less.

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...

Strange. I uploaded it here too: https://ibb.co/yFTycjJ

I had tried the single block but I didn't see any compensated values. I'll try once again with more attention. If anybody shares the appropriate parameters for compensated values, I'll be much appreciated.

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...

Curiosity, to check how the tool tip is moving exactly. I'm newbie, so I need to check every my steps carefully.

You mean only in 3 points (2 points of tapered line, 1 point of the end Z-20), just for a fraction of second, the compensated coordinates are shown? If I reset the program in the middle of the tapered line (Control parameters are set such a way that it still shows T0101 coordinates even by...

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...

I check it in handwheel mode with an indicator preload of .4 mm. Should I check backlash in Auto and motion?

@mach ramsey mn By attaching a dial indicator base to chuck (In lock mode) and making the turret close to it in Z direction. 0.1 mm load in 0.01 steps then reverting in Z. Yes it is significant, but inputting the value with no change in result is normal?

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...
