Prog. for form Explanation
E F A-D T
x x x x Reference point in the plane axis (always diameter)
x x x x Reference point on longitudinal axis (abs)
x x x x Form of undercut (capital letters, e.g. "T")
Selection, table from which the undercut values should be taken
A = External, reference DIN76, A = normal
B = External, reference DIN76, B = short
C = Internal, reference DIN76, C = normal
D = Internal, reference DIN76, D = short
E = Reference DIN509
F = Reference DIN509
T = Free form
x x x x Position of undercut (parallel Z)
0 = External +Z: \____|
1 = External -Z: |____/
2 = Internal +Z: /-----|
3 = Internal -Z: |-----\
x x x x Safety clearance (inc)
x x x x Machining feedrate (mm/rev)
- - x x Machining type
UNITS: Machining
1 = Roughing
2 = Finishing
3 = Roughing + finishing
TENS: Machining strategy
0 = Parallel to contour
1 = Longitudinal
Undercut forms E and F are always machined in a single pass like finishing.
