    Incremental Rotary Axis Code for Subspindle - Fanuc-Takisawa LA250YS Lathe

    I don't think so. Anytime I run an absolute rotary code (C or A) the axis moves in the direction that results in the shortest distance traveled. This includes using negative values. You wouldn't think that'd be right, but I guess it's a bit like using "R" with G2 and G3; you may have multiple...

    Incremental Rotary Axis Code for Subspindle - Fanuc-Takisawa LA250YS Lathe

    Yes, that'd be right. The three programs below will result in the same machine motion. G1G99C0F3600. G1G99C0F3600. G1G99C0F3600. C120. C120. C120. C240. C240. C-120. C360. C0. C720. C480. C120. C1200. The one clear advantage with this method is when you are drilling a bolt...

    Incremental Rotary Axis Code for Subspindle - Fanuc-Takisawa LA250YS Lathe

    G91 doesn't work on lathes as on mills. Anytime it's tried, an "improper G-code alarm" is displayed. But just in case I have a preexisting bias, I tried it out and it threw the same alarm. I saw a thread discussing the "B" axis, which is really a linear sub-spindle axis, which I also haven't...

    Incremental Rotary Axis Code for Subspindle - Fanuc-Takisawa LA250YS Lathe

    Going to the relative screen on the control is a good idea I didn't think of; however, it only shows X, Z, C, and Y as changing to U, W, H, and V. Axes A, B, and T (turret axis, kind of irrelevant but whatever), all remain the same. On this control/machine, the rotary axis must be homed before...

    Incremental Rotary Axis Code for Subspindle - Fanuc-Takisawa LA250YS Lathe

    Trying to figure out what code would enable incremental C axis motion on a Fanuc 32i-Model B controlled lathe. The sub-spindle rotary axis and the code I use to move it is "A" and the main spindle uses "C" for it's rotary axis. Example code below activates, homes, and moves the rotary axis to...

    Coolant mix guide: brands and practices (asking if it exists, not offering advice)

    We've used Hocut 795, and switched to 795B recently, which seemed to decrease any staining if parts were left overnight with coolant sitting on them. Mostly running aluminum and steel, and over 5 years and 17 machines, I've only seen 2 machines have their tank go bad. Both cases were machines...

    Combining X/Z and Y Offsets Pages

    I appreciate the warning. I'm a one-man shop so I'm the only one to blame if a mistake is made :) Though I've ran 5 Y axis lathes (at the day job before starting out on my own) this is the first one with the Y offsets tucked away elsewhere. The idea this was an intentional design and not just...

    Combining X/Z and Y Offsets Pages

    Thanks so much! Exactly what I wanted, makes setup so much easier and faster. Pic attached for anyone who wants to try this out and wants to know what happens ahead of time. Really appreciate the help, dcrace.

    Combining X/Z and Y Offsets Pages

    Is there a way to get the Y-axis offsets onto the same page as the X/Z/R/T offsets? Currently, the control uses a different page to display and adjust Y offsets, which can be a bit cumbersome to access. Of course, I'm hoping there's a simple parameter switch to permit me to make this change, but...
