Home » Materials Science and Manufacturing Engineering » Materials Science and Manufacturing Engineering Miscellaneous » Question

The total angular movement (in degrees) of a lead screw with a pitch of 5.0 mm to drive the work table by a distance of 200 mm in a NC machine is

1. 14400
2. 28800
3. 57600
4. 72000

Correct Option: A

pitch = 5 mm No. of Revolution required for 200 mm travel distance

=	200	= 40rev.
	5

∴ 40 × 360 = 1400°
