Question

A point 'P' on a CNC controlled XY- stage is moved to another point 'Q' using the coordinate system shown in the figure below and rapid positioning command (G00). A pair of stepping motors with maximum speed of 800 rpm, controlling both the X and Y motion of the stage, are directly coupled to a pair of lead screws, each with a uniform pitch of 0.5 mm. The time needed to position the point 'P' to the point 'Q' is________minutes (round off to 2 decimal places).

V_{max} = \text{pitch} \times \text{RPM} = 0.5 \text{ mm} \times 800 \text{ rpm} = 400 \text{ mm/min}
