Hi I think that if i can control - programmable control - torque on each axis X Y Z and torque on spindle, than i will never break tap during tapping, and use 100% live time of cutter. i think if EMC2 create code something like M500X120 which means torque (or axial force for axis X) should not exceed 120 HM.( when it does machine will stop all motion and give some alarm signal) than damage of tool, part, machine them self can be greatly avoided. thanks aram
