Hello all,
Its great to see all of the help available from other machinists.
I have a new HAAS TM-3P mill with the Renishaw wireless OTS and OMP-40. The Probe option was about $7,000.00. The specs for the probe were +/- 1 um. Of course I knew that that figure was calculated under controlled conditions. So, my assumption was that given a few tenths runout on the spindle and OTS surface plate flatness of less than .0001", I would easily get Length and Diameter results of .0005". All of my Probing Diameter results were between .0022" and .0045" off comparing to the actual cut and all were measuring too large of a diameter.
For me, this negates the value of the Probe as I would have to make a cut, measure it and enter the difference in the "Wear" column on the Tool Offset page of the VPS for every tool. The HAAS folks came out and their fix was to change the diameter value from that printed on the Calibration Master. That, of course, only works for the cutters that are off the same amount.
Has anyone had this problem. Thank you.
