When Broaching blind keyways we recommend broaching into a relief area
NOTE: We do not recommend that you taper or radius out of a blind keyway. This will result in a crash. You must have an adequate groove or cross-hole relief area
Q: If a 3/16 wide keyway with a 2.5” Length of Cut & has a 3/16″ wide groove relief, is that enough?
A: Probably not. Don’t forget that you do not have an actual 3/16 relief as you are stopping .100″ past the end of the keyway to leave space for deceleration. If you stop to close the end of the keyway you can decelerate in the actual keyway leaving a taper or lip. How much space you need for deceleration depends on your machine. SO, if you are stopping .100” into a .1875 groove that only leaves you .0875” of space to jam 2.5” of material. Not enough.
