Question

What is the error caused when transverse movement is not parallel with spindle axis on milling machine?

(a) Milled surface will not be square to base

(b) Depth of cut will vary

(c) Eccentricity of tapered hole

(d) Axial slip

This question was posed to me by my school principal while I was bunking the class.

The origin of the question is Alignment Tests on Milling Machine topic in division Machine Tool Metrology of Engineering Metrology

Answer 1

Right answer is (b) Depth of cut will vary

Best explanation: To test transverse movement parallel with spindle axis. The table is set in its mean position and dial gauge is fixed. The table is crosswise moved and any deviation on reading of dial gauge is noted. Due to this error when cross slide is moved, the depth of cut will vary.
