5.1 ICP Contours
The Interactive Contour Programming (ICP) feature
provides graphic support when you are defining the
workpiece contours for ICP cycles. (ICP is the
abbreviation of "Interactive Contour Programming".)
The contours are defined using linear and circular
contour elements as well as form elements like
chamfers, roundings, and undercuts.
Calculation of contour geometry
MANUALplus automatically calculates all missing
coordinates, points of intersection, center points, etc.
that can be derived mathematically.
If the entered data permit several mathematically
possible solutions, you can inspect the individual
solutions and select the proposal that matches the
drawing.
Each unsolved contour element is represented by a
small symbol below the graphic window.
MANUALplus displays all contour elements that can
be drawn, even if they are not yet fully defined.
Form elements
You can insert chamfers and roundings at each corner
of the contour. Undercuts according to DIN 76, DIN
509 E, DIN 509 F are only possible at paraxial,
orthogonal contour corners.
You have the following alternatives for entering form
elements:
„ Enter all contour elements, including the form
elements, in the sequence in which they are given
in the workpiece drawing.
„ First define the "rough contour" without the form
elements. Then you superimpose the form
elements (see also “Programming Changes to ICP
Contours” on page 254).
Special feed
You can assign a special feed to contour elements,
which will be used for finish-machining these
elements.
For lathes used in the machining of ICP
contours, you need to define the tool
angle and point angle.
