I am newer to the wire EDM and our shop has a Mitsubishi MV1200s. I am having a little troubles with my parts coming out square when working with tighter tolerance parts. If I cut a dowel pin hole typically it will have .0002 tenths of taper from top to bottom on a 3/4" piece of material however if I turn off power master and adapt control and I slow down the feed rate on the first two passes to .080 they will come out less then a tenth of taper. Another issue I have ran into is the only way I have been able to get the outside of my parts square to within a .0001" consistently is if I use the same method as I do with the dowel pin holes and I slow down all 4 passes (we do not have the fine machining option to allow more passes). I know there is more to learn and I'm sure there is a better way to go about it. my question is if there is any way to speed up the process by using an adjustment in the machine or even programming it differently then I have been. This is kind of new waters as far cutting gauges in our shop so if anyone has any insight on a different way to go about it please feel free to add to it.
In order to get the accuracy I have had to cut a test piece(typically about a .750" square), measure the walls, then manually move the wire to get the straightness I need for some of these parts. The material that is going in the machine is tool steel, typically A2 that is ground and indicates within .00005 once on the machine.
Thank you in advance for any advice
