Title:
METHOD AND DEVICE FOR GRINDING WORK IN THE FORM OF NON-CIRCULAR ROTARY BODY, AND CAM SHAFT
Document Type and Number:
WIPO Patent Application WO/2004/048035
Kind Code:
A1
Abstract:
In grinding the outer peripheral surface of work (10) in the form of a non-circular rotary body, while being rotated around its axis, by a rotary grindstone (22) adapted to be advanced and retracted by NC control according to the profile of the work (10), two steps are performed; the first step of detecting a predetermined amount of lift of the outer peripheral surface of the work (10) at a fixed point so as to compute the reference phase of the work (10), and the second step of advancing and retracting the rotary grindstone (22) by NC control on the basis of the reference phase of the work (10) computed in the first step, so as to grind the outer peripheral surface of the work (10). Thus, computation of the reference phase of work can be accurately effected without forming a special recess in the outer peripheral surface of work.
