[Emc-users] Cam grinding....

[Dave <EMC@DC9.TZO.com>]

Guys,

I know a guy who is interested in using EMC2 to control a cam grinding 
operation  - as in automotive type camshafts cam lobe grinding.

Usually a large diameter grinding wheel is moved in and out to grind the 
cam profile.   Compensation for the wheel diameter is required.

Has anyone ever done this before with EMC2 or otherwise?    Attached is 
a diagram which is exaggerated in that the grinding wheel is usually 
much larger.

A cam grinding machine looks like a lathe but the grinding wheel which 
is usually .75 inches wide and usually quite large - perhaps 12 inches 
or more in diameter and it moves in and out as the camshaft revolves to 
grind the profile.

Here is a diagram that shows the wheel to cam situation:
