You have to check the actual tool diameter. They are not always the nominal size even when new.
Hello to all
I have a HAAS VF-1 and its a great machine for what I do.
I am running into a problem in that I tried to mill out a square and a circle both with 1" sides and diameter out of a .125 aluminum plate..
I initially tried using a 1/8" inch flat endmill. When the job was done, I measured with two different digital calipers the resulting dimensions and found them to be off by 17 thous. So out of a theoretical 1000 thou (1 inch), I got 983 thous. This was consistant in both the circle and the square.
I then ran the same job with a 5/16 flat end mill to see what happens. This time, the actual measurement after milling was 1061 (over by 61 thous) and again consistent in both the circle and the square.
I am using Mastercam MC9 as a software and have attached images and screenshots as well as the files. I would be grateful if someone can help me figure this out?
Thanks!

Have you done roughing and then a finish pass?
