Function
You can create and machine complex contours in CONTOUR mode.
The integrated contour calculator calculates the points of intersection
of the individual contour elements taking account of geometric
relationships. You can link up to 100 contour elements with one
another. The contour transition elements radius and chamfer are
available in addition.
Contour elements are:
• Start point
• Straight line (face, longitudinal, conical)
• Circular arc
Machining the contour can take account of the blank contour to be
defined before the finished part contour.
With stock removal, residual material is automatically detected and an
updated blank contour generated. The excess material can be
removed using a suitable tool with the "Residual material" function.
Operating mode CONTOUR offers you a parts program management
function under soft key "Directory" (see Section "Parts program
Management"). Existing contours can be called up again and edited in
operating mode CONTOUR.
Operating mode CONTOUR is a software option.
