Parameter Description
Machining
● ∇ (roughing)
● ∇∇∇ (finishing)
● ∇+∇∇∇ (complete machining)
Machining
● face
direction
● longitudinal
● parallel to the contour
The machining direction depends on the stock removal direction and choice of tool.
Position
● front
● back
● inside
● outside
D Maximum depth infeed - (only for ∇)
DX Maximum depth infeed - (only for parallel to the contour, as an alternative to D)
DZ Maximum depth infeed - (only for position parallel to the contour and UX)
UX or U Finishing allowance in X or finishing allowance in X and Z – (only for ∇)
UZ Finishing allowance in Z – (only for UX)
BL Blank description (only for ∇)
● Cylinder (described using XD, ZD)
● Allowance (XD and ZD on the finished part contour)
● Contour (additional CYCLE62 call with blank contour – e.g. cast iron mold)
XD - (only for ∇ machining)
- (only for blank description, cylinder and allowance)
● For blank description, cylinder
● For blank description, allowance

● from inside to outside
● from outside to inside
● from end face to rear side
● from rear side to end face
– Version, absolute:
Cylinder dimension ∅ (abs)
– Version incremental:
