    Programs twice the size in NC memory

    Why is it that sometimes a program takes double the space in NC memory, for example, Windows Explorer says 23kb and control says 54kb? When transferred back to PC, the filesize becomes smaller again....
  2. Re: Very basic fundamental question regarding CMM (sanity check actually)

    OK, maybe a better question would have been "Is the measured point always the same as the contact point regardless of direction/approach vector when using a touch probe?", assuming everything's been...
  3. Very basic fundamental question regarding CMM (sanity check actually)

    In the picture, does the 3D coordinate measuring machine's touch probe register the measured point at point a. or point b. ?

    G13.1 oddity

    Intregrex 200 / 640mt pro

    I don't have the code at hand now, but first I perform some face contour milling using G12.1 (mill mode), no problem there, and after that some face milling using XY-axis...
  5. How is Y-axis brake implemented in a Mill-Turn machine?

    There is no clamp M-code for Y-axis. There is however for B and C axis. How does Y-axis stay in place during heavy roughing (turning) operations that tend to push the axis? Is it supported by servo...
  6. Z compensation for reground spindle with a single parameter

    A spindle has been reground. We know the exact amount of Z difference between tool length in old and new (regound) spindle. However we don't want to re-measure every tool in magazine nor do we want...

    Read tool life data into macro variable

    Hi,

    Tool life data can be set using G10, but how can I read the data?

    Thanks!

    Grinding on a CNC machining center

    I keep hearing that you should never grind on a CNC machine that is not specifically a grinding machine because it will destroy its precision. But I have never heard actual experience proving this....

    Spindle load percentages, parameter range?

    Hi,
    Under custom menu, there is a load monitor screen with one value (max allowed spindle %) per each tool pot. Is there some common parameter range for these values, so that they could be changed...
  12. Re: Compensate feed on arc moves with full radius compensation (32i)

    Thanks for answering. No, it's not an option. I was really hoping there was a parameter so that the control would automatically compensate depending on value in the radius field. Without feed...
  13. Compensate feed on arc moves with full radius compensation (32i)

    Is it possible to slow down arc moves when using full radius compensation with some parameter in this control? Control is 32i-A.
  14. Re: Fanuc 32i, MDI won't clear after cycle finished

    Thank you, although I didn't chance the MDI behavior because the operators are used to using it this way.

    Re: G43 being cancelled on G28

    Are you saying that there is a parameter to not cancel G43 on G28, or that there is another G-code that will reapply the previous G43 Hx after G28?

    G43 being cancelled on G28

    The control is Fanuc 32.

    I am programming a four axis HMC pallet machine. Before rotary indexing, Z is moved to the reference position to avoid collision. The problem is, G28 G91 Z0 cancels G43....
  17. Re: Fanuc 32i, MDI won't clear after cycle finished

    Nice :) On 18i I'm used to typing several lines of code in MDI and then cycle start would run all those lines entered. However, on 32i it will only execute the last block, unless I move the cursor to...

    Fanuc 32i, spaces removed in Auto mode

    Under program check the code is shown as G0X123Y342... and in edit mode G0 X123 Y342... I guess there is a parameter for this?

    Thanks again.
  19. Fanuc 32i, MDI won't clear after cycle finished

    On 18i, MDI program is automatically cleared once finished. How do I make it so that on 32i the behavior is similar?

    Thank you.

    Re: Spindle fails to orient unless M5 commanded

    It is completely random. Could be a sensor issue, it is a 10 year old machine after all. Just wondering if anybody else has experienced this issue.

    Re: Spindle fails to orient unless M5 commanded

    Well the question is, why does it orient sometimes and sometimes it doesn't? A bug in the control (OSP-P200M)? An older machine with U10M always orients from spindle on state.

    Spindle fails to orient unless M5 commanded

    I removed M5 from Okuma's postprocessor before toolchange to shorten cycle time and now the spindle automatically stops (=orients) when moving to tool change position. Or at least, in 90% cases it...

  25. 18i-tB ignores wear under non-auto condition

    Is this a parameter issue? When I run a program in auto mode, tools are using wear values properly after execuing a T command, but when in MDI, executing eg. T0404 ignores wear altogether.

    Thanks...

    Re: G130/G131 = no effect whatsoever

    Yep.
    Aye.
    Yes it is.
    Fail. Tried G131, G131 J0 F20000, G131 J1 E0.02,... but it stays off.


    I really don't understand what is going on here. Anybody from Okuma?

    VERY basic question, to which I never got the answer, so... How do I cancel T? The only way so far is to call M6 which puts an unnecessary tool to spindle. Is there any faster way? I use tool...
