Function
Free contour programming is a support tool for the editor. The contour
programming function enables you to create simple and complex
contours.
An integrated contour calculator (geometry processor) calculates any
missing parameters for you, provided that they can be calculated from
other parameters. You can link together contour elements. Contour
transition elements "radius" and "chamfer" are also provided.
The programmed contours are transferred to the edited part program.
The scope of functions of the contour calculator differs depending on
the chosen technology:
Functions which are only available in the turning technology include:
• Toggling between radius/diameter programming (DIAMON,
DIAMOF, DIAM90)
• Chamfer/radius at the start and end of the contour
• Undercuts as transition elements between two axially parallel
straight lines, where one runs horizontally and the other vertically
(Form E, Form F, thread undercut, free undercut)
Functions which are only available in the milling technology include:
• Contours with symmetry (mirroring)
• Contours with repetitions
• Combinations of both
The contour calculator takes into account channel-specific display
machine data. As it does not know which channel the program is
being created for, it always analyzes the display machine data of the
1st channel.
Allowances parallel to the contour, which are required for grinding, can
be created by free contour programming and modified again if
necessary.
