Today I read a Mori Seiki manual on CI subject. Its example made me more confused. G2/G3 direction is against the image of the first post (Taken from a Doosan manual). What am I interpreting wrongly? The defined plane is G19, so C is pseudo Y and Z is pseudo X? I'm sinking...
Thanks. This way, I can understand your previous image about CI in a vertical machining center.
Now let me ask about the image of my first post. Is my pseudo X and pseudo Y correct?
Thanks for all your explanations. You are one of the most knowledgeable persons of the forum, always try to read your posts carefully to learn new things.
This time the point is hard to understand for me. 😵💫
A 3 axis lathe equipped with C axis. I know the thumb rule to determine the direction of G2/G3 in XY or YZ or ZX plane (looking from the third view in positive...). But can't figure out what is the third view to look from to define direction of G2/G3 in the ZC plane. Appreciated for your answers...

Thank you for your suggestions. I can use maximum 3 stations for live tools. In my first experience 431 SS is not a hard material to machine.
The slot depth is 16 mm. And a clean wall is important for me.
After your suggestions, what I'm going to try, is roughing it out...
Hi!
A 3 axis turning machine Doosan Puma 300M is to be used for machining this cylindrical hole. Its radius is 2.5 mm, so I used a 5 mm solid Carbide end mill (Kennametal brand) as live tool. My method is a zig zag move:
(0.5 mm each pass as ramp)
S1500
G01 Z-0.5 H70 F0.02
Z-1 H-70
....
Z-17...
I have not found any info about the chuck pressure needed for an operation in my lathe manuals (A Colchester Tornado A90 machine). Does anybody have any material for this machine or any other machine? Wanna have a more view on this subject.
Suppose a part is held in a hydraulic chuck and still...
Actually it was a comprehensive manual for the CNC machine, these charts were in the chuck part of the manual.
What is 30 min curve? Operation for 30 min only?
How can I use these power and torque in reality? What I do, is setting up a part in the CNC lathe, and machine it. I don't know more...
Hi!
I was reading a manual about CNC lathe chuck pressure that encountered this chart. I don't how to interpret it. Please may you describe it with 1 or 2 examples?
Its a 55 degree DCxx insert. You mean insert seat and holder clearance is not the same as the picture above? Then the clearance angle (93-95) would not change by different seat and holder?
