Short description
Calculating tool compensation data
The SINUMERIK 840D/810D controls 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 selection selectable: Immediate or via selectable M function
• Tool radius compensation:
Basic logic functions: Tool Offset (W1)
Function Manual, 11/2006, 6FC5397-0BP10-2BA0
– 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
– 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
