  • Poll Do you Square up your Fixture/Part to your machine?

    How often do you square up your Fixture/Part true to the Machine axis?

    100% of the time
    75% of the time
    50% of the time

    Have to say never. I measure co-extruded Fuel Tanks and have to put their +Z to the CMM -Y otherwise I'd never get around them to measure all the features.

    It goes "dink" so it must be workin'

      I try to get the workpiece as square to the machine as I can. I keep a fixture on the machine at all times that I indicate square before clamping. Everything else comes off of that. My jog box is the older model that doesn't have the options of moving square to the part or alignment.

        try to get it reasonably square because your tip angles may not work out as originally intended if your part is skewed.

        EDIT: paul when you create a new post there is an option for a poll where people can actually vote on the answers.

        also, you are double and triple posting again

          almost always

          I would say something like 95% of the time. If no effort is made to square the part to machine axis it is because it is a round part standing on end with no rotational features. Not many of those, but a few.

            i use the 1/4-20 tapped holes in the rayco plate to get it close then let the computerized alignment take over. as far as indicating it in the "old fashioned way" w/in .0001. never. those days are long gone.

              Just give the RAYCO plate the hairy eyeball and thumb alignment. That's close enough for the machine to do the rest.

                I also use a RAYCO plate the majority of the time. I generally square it up to the threaded inserts in my plate, it's close enough to square so that my 90° probes are square to my workpiece.

                  Squaring to the X-Y makes probing some features much easier.

                    I am also on the rayco plate band waggon now. And i love it no more 2 faced tape and strap clamps.

                      Probably 50-50. Like posted previously if there are tip angle changes...a must, we dont have rayco plate or similiar...Run the probe in the axis' to get it as close as I can.

                        I use a Rayco system, and have a 90° corner bolted to the plate. I use it as much as possible to give myself the maximum shank clearance in features of depth. I still do mathematical alignments with measured features.

                          98% of the time. Sometimes I'll purposely lay a part crooked to prove to a machinist that my alignment works.
                          When in doubt, post code. A second set of eyes might see something you missed.

                            Most of our parts are round, but they do have holes in them. I usually eyeball the 1st hole to X plus position, but I don't spend too much time on it.
