Offline Deviation

Rookie
Never seen a program run OFFLINE and have deviation in the numbers. Brand new program, never been on a machine. How in the world can it have deviation in the x,y, and z?

Attaching a screenshot of the code and the point nominal deviation window. No PND...

  • I usually program at 5 decimal places also. These are the very first points that are taken. I do recall an external alignment right before these. I'll check that alignment in the morning. Thanks

    I hate external alignments and any manner shape or form of 'CAD = PART'. (probably because I don't understand them) If you are using a model, are you sure its correct? I usually just use auto feature dialogue boxes in manual mode, take hits on the model and look to see what numbers fill the axis and vector fields then go from there. If you have your part reasonably aligned to the machine axis, you should only need one hit to begin DCC mode. I like this better than a 'read point' because the operators won't inadvertantly start the program from out in space when they click OK before the probe is correctly positioned.
