Hi,
I'm new to this forum. Just bought my first CNC mill which is a Bridgeport Interact Series 1. I'm just getting my head around the cycles which the machine has in it's TNC145 control.
At the moment I'm trying to get the tapping cycle working successfully, though I keep stripping the thread as the tool is retracted. I'm using a M8 x 1.25 spiral flute tap on an aluminium plate. I'm using a feedrate of 625mm/min, spindle speed 500RPM and dwell time 0sec. The thread seems to be cutting okay as the spindle plunges into the workpiece (clockwise), though then dwells for 1 second with the spindle rotating before the spindle is automatically reversed and the tap is retracted at the same federate and spindle rpm.
Is there a way to remove this 1 second dwell between spindle rotations? I feel this is causing the thread to be stripped out....
Thanks,
Ben
