Short description

Calculating tool compensation data
The SINUMERIK 840D control can be used to calculate the following tool compensation data:
• Length compensation
• Radius compensation
• Storage of tool data in a flexible tool offset memory:
- Tool identification with T numbers from 0 to 32000
- Definition of a tool with a maximum of 9 cutting edges
- Cutting edge described by up to 25 tool parameters
• Tool selection selectable: Immediate or via selectable M function
• Tool radius compensation:
- Selection and deselection strategy configurable: Normal or contour­related
- Compensation active for all interpolation types:
Linear
Circle
Helical
Spline
Polynomial
Involute
- Compensation at outer corners selectable:
Transition circle/ellipse (G450) or equidistant intersection (G451)
- Parameter­driven adaptation of G450/G451 functions to the contour
- Free traversing on outer corners with G450 and DISC parameter
- Number of dummy blocks without axis motion selectable in the compensation plane
- Collision detection selectable:
Possible contour violations are detected predictively, if:
- Path is shorter than tool radius
- Width of an inside corner is shorter than the tool diameter
- Keep tool radius compensation constant
- Intersection procedure for polynomials
