Im having issues on a 3x mill post, where the tapping operations are causing the tap to just hover over the hole and move at an extremely slow rate. I think its reading the FPR as the FPM causing the issue. Im using a HAAS vf4 mill. pls help! Ive tried some solutions through other forums but nothing works so far
G84 Tapping on the Haas controller defaults to FPM(feed per minute) and the feed rate value should also then be in FPM. If your Haas post processor is outputting the feed rate in FPR(feed per revolution) then we need to get that fixed for you. It should be an easy fix.
PS: On the Haas controller you can tap in FPR but there must be a G95 output before the tapping cycle to put the control in FPR mode. Then right after the G80 cancelling the tap cycle there must ba a G94 before you do any other milling to get back to FPM mode or else things will get exciting.
