Suppose point $$P1$$ in $$APT$$ (Automatically programmed Tool) programming is coded by statement
$$P1 = POINT/XSMALL,\,\,\,INTOF,\,\,\,LN1,\,\,CR1$$

The coded geometric situation without causing error is

A stepper motor has $$150$$ steps. The output shaft of the motor is directly coupled to a lead screw of pitch $$4mm,$$ which drives a table. If the frequency of pulse supply to the motor is $$200Hz$$, the speed of the table (in $$mm/min)$$ is

In a $$CNC$$ feed drive, a stepper motor with step angle of $$1.8deg$$ drives a lead screw with pitch of $$2mm.$$ The basic length unit $$(BLU)$$ for this drive is

A $$10mm$$ diameter annealed steel wire is drawn through a die at a speed of $$0.5/sec$$ to reduce the diameter by $$20\% $$. The yield stress of the material is $$800MPa.$$

Neglecting friction and strain hardening, the stress required for drawing (in $$MPa$$) is
