The actual finish is usually rougher than
theoretical calculation.
Other factors
not calculated help to ultimatley determine finish.

Radial Chip Thinning Feed Calculator
|
Solution
|
|
|
Whenever the radial width is less than half the tool diameter
(as in Rw2) the chip thickness is less than the feed per tooth and additional
feed is possible using the chip thinning calculation.

Programmed Feedrate for Interpolating a Bore
|
Solution
|
|
|
|
|
When moving in a circular motion, the actual feed rate at the
outside diameter differes from the programmed feed rate. Use the feed rate below when boring out a
large bore, the centerline feed rate is calculated and inserted into program
to compensate for the motion.
