6.4.3 FB 436 MC_CamInterpolate - Interpolating cams
Purpose
• The "MC_CamInterpolate" technology function interpolates a cam disk. After its
interpolation, the cam disk can be used for camming.
• Interpolation closes the gaps between the interpolation points and polynomials
contained, according to the specified type of interpolation.
Applicable to
• Cam disks
Requirements
• The cam is in editing mode
Editing mode is started by the technology function "MC_CamClear" and ends
with the interpolation of the cam by the technology function
"MC_CamInterpolate". This enables operation of the cam disk for camming.
Marginal conditions
• Rule applied to interpolation points:
- With superimposed interpolation points, the last created interpolation point
takes priority
• Rule applied to segments:
- The gaps between segments are filed with an interpolated cam.
- The start point of a segment is relevant for overlapping segments; the
previous segment is truncated, starting at this position.
• Rule applied to mixed mode cam disks (segments and interpolation points):
- The start point takes priority as in a segmented cam.
• With the interpolation function, the attempt is made to perform a cyclically
relative (constant velocity) interpolation of the cam disk. That is, the gradient is
equalized, if possible, at the start and end positions.
