VI. CLEARANCE ANGLES —CORNER
After determining the necessary clearance angle and corner angle, read the correct
settings for radial roll and axial tilt of the universal workhead at the horizontal and
vertical intersection of these values.
EXAMPLE: For 7 degrees of clearance and a
45 degree corner angle, the radial roll is 5 degrees and the axial tilt is 5 degrees.
To set the radial roll, consult the clearance angle table for cup wheels. Set the
axial tilt on the upper swivel of the workhead.
This table is
included as an alternate method obtaining the clearance angle on the
chamfer of shell end mills, face mills, and other similar tools. In many instances,
adequate clearance can be obtained by swiveling the workhead to the necessary
corner angle and then tilting the Wheelhead or workhead to the desired primary or
secondary angle of these lands at the periphery or face of the cutter.
