17. Choice of cross-section planes during simulation
2-D Simulation
Large simulation window
Simulation allows comprehensive analysis of tool geometry before grinding
The user-friendly interface and simulation facility makes work highly efficient

18. All grinding operations are simulated
2-D Simulation
Analysis of critical corner radius area for following geometry: corner radius 8 mm flute depth 4 mm
Simulation allows the smallest details to be analyzed, with no need to grind
All grinding operations are simulated

19. Simulation displays are true to scale
Example of an analyze: If the gash out is done without a radius, the contouring error is mm.
2-D Simulation
Simulation displays are true to scale
Distances and angles can be determined to micrometer accuracy

20. The same cross-section with optimum rounded gash out
2-D Simulation
By applying a radius to the gash out, contouring is 100% accurate.

32. Form cutters Lead type: Helical, axis angle or straight
Falling contours with relief angles on all sides
Flute form compensation

33. Sharp edges can be automatically rounded off.
Form cutters
The required form is read from a DXF file

34. Form cutters
The entire shape can be ground in one process or subdivided into several steps.
The axial relief angle along the shape can be programmed separately for each step.

35. Parallel land width using flute form compensation.
Form cutters
The flute form can be compensated for when grinding the reliefs. This means the contour can be ground accurately and without distortion.
