The invention discloses a control method for a planar conjugate cam contour detecting and grinding device. The technical point is that when a grinding wheel grinding head of a grinding mechanism of a grinding controlling and detecting device performs grinding on an outer contour of a planar conjugate cam, a second laser measuring head of a cam inner contour detection device performs ...

FOR CADD/CAM Some dimensioning and tolerance guidelines for use in conjunction with CADD/CAM: • Geometry tolerancing is necessary to control specific geometric form and location. • Major features of the part should be used to establish the basic coordinate system, but are not necessary defined as datum.

A cam grinder in which the angular velocity of the workpiece is cyclically varied to reduce variations in the contour velocity. A work table is controlled by a master cam to move relative to a grinding wheel in accord with the desired profile. The workpiece is driven by a spindle carrying a wheel driven by a belt which passes over a driving wheel.

Guys, I have a job that requires the faces to be flat to 0.0002" over a 10" x 12" x 0.200" thick ceramic plate. To add to the difficulty, there are 60 holes of …
