Combine command doesn't work(failed to perform boolean operation)

[steven_zhuQDRBU]

I am creating a cam mechanism for some project, and I am creating some grooves on it because there would be a bar sliding back and forth. To create the grooves I stitched together a body. I have one groove but I want 6 of them all spaced evenly on the cam. I tried to create another body with the shape of the groove and cut it into the cylinder(combine command) but it didn't work. Can somebody please help me?

Circular Pattern the successful cut/s.

do I have to unstitch the cutting tool

[davebYYPCU]

No, your pic shows one cut, 

Now you circular Pattern that feature set, count 6.

Might help….

if I do that it just creates more faces it doesn't cut the shape

instead of doing a circular pattern for the feature I just unstitched everything and did a circular pattern for the groove. Then I stitched everything back together.
