Tool Diameter Wear ?
« on: March 17, 2007, 01:43:31 PM »
Hello Everyone,

I am working on a small project on my ShopTask machine using Mach3.  After making several duplicates of the same part I noticed that my end mill wasn't cutting as clean as it had on the first part and that my tollerances were starting to drift out of spec.  I replaced the end mill with one that had been resharpened and the cuts looked much better.  Then is discovered that my parts were really out of tollerance.  For example I milled out a round hole that is supposed to be 1.757 inches in diameter and it only measures 1.744 inches.  I checked several other different dimensions and the results tell me that my end mill is under size by about 0.0065.

When I look at the tool table dialog in Mach3 there is a field named "Diameter Wear".

If I enter a value in the Diameter Wear column for my tool, will it cause Mach3 to correct for my under sized tool?

If this is the case, what value should I put into this field?

I don't think diameter wear does anything. But, if you program using cutter comp (G41/G42) the tool diameter in the table will be used to calculate you toolpaths.
