In an open loop, point-to-point controlled $$CN$$ drilling machine, a stepper motor, producing $$200$$ angular steps per revolution drives the table of a drilling machine by one angular step per each pulse generated by a pulse generator (shown in figure). Each angular step moves the table by one Basic Length Unit $$(BLU)$$ along $$X$$ axis with a lead screw having a pitch of $$4mm.$$ If the frequency of pulse generator is doubled, the $$BLU$$ will

Each axis of $$NC$$ machine is driven by a stepper motor drive with a lead screw. The pitch of lead screw is $$p$$ $$mm.$$ The step angle of stepper motor per pulse input is $$\alpha $$ degrees/pulse. The ratio of gear drive in stepper motor drive is $$g$$(number of turns of the motor for each single turn of the lead screw). The number of pulses required to achieve a linear movement of $$x$$ $$mm$$ is

A $$CNC$$ instruction $$G91\,\,\,G01\,\,\,X30\,\,\,Y40\,\,\,F100$$ commands the movement of tool along the path at a feed rate of $$100mm/min$$ $$(G91$$-incremental format and $$G01$$-linear interpolation). The feed rate of the tool (in $$mm/min)$$ along the $$X$$ axis will be _______________
