Scenario: I wire a rectangular slot for a punch in 2" steel material @ 0.2 x 0.4456. using 0.010 wire. I have a Mits. MV2400S that has straight comp that is supposed to adjust for straightness when you set your Z1, Z2, Z5 and also you have to go into your EPAC's for the second and third passes and adjust the T and CC settings for the actual thickness of the part in mm. Then once I get that close(the bottom to a snug tap fit at least), I wind up dealing with the slot smaller in the middle or hour glass affect. So then I go back into the first and second skim EPAC's and raise the VG .5 ish. I still have a slight taper per say. My tolerance is very small like + 0.00005 -0.00000 per side. The fits like firm tap fit, light tap fit, and slip fit are how they classify them. I also read to adjust the FA and VO as well. By the time you are done some what, now you have to alter passes and offsets. I mostly deal with dies, punches, punch holder blocks, all with dowel holes as well.
Does anyone have a magic wand or solution to getting a straight hole or slot or is this normal? I get the whole wire deterioration as it cuts part but there has got to be a way around that. What is tipping the wire? Is that for taper cuts or angled holes? I don't understand how or when you would do that and for what purpose, but would doing this help?
If the people who create the EPAC tech already know that the part will have a drum, hour glass, or bigger at top than the bottom happen, then why don't they already have all the tweaks and adjustments already adjusted? This would be greatly appreciated and save me money on antacids, Extra Strength Tylenol, and slow down the aging process immensely!
What am I missing or doing wrong? This is ALWAYS an issue!
Thanks for any and all input,
