6.5 Free contour programming
Function
The free contour programming is a support tool for the editor.
The contour programming function enables you to create simple or
complex contours.
An integrated contour calculator calculates any missing parameters
for you, provided that they can be computed from other parameters.
You can concatenate contour elements. Contour transition elements
"radius" and "chamfer" are also provided to help you chain contour
elements.
The programmed contours are transferred to the edited part program.
The contour calculator (geometry processor) includes channel-
specific display machine data in software versions SW 6.2 and
higher. As it does not know which channel the program is being
created for, it always analyzes the display machine data of the 1st
channel.
In software versions SW 6.3 and higher, allowances parallel to the
contour, as needed for grinding, can be created by free contour
programming and modified again if necessary.
The following are contour elements:
·
Starting point
·
Straight line (planar, longitudinal, inclined)
·
Circular Arc
·
The pseudo-contour element pole is available in HMI Advanced
SW 6.2 or later. Straight lines and circular arcs can also be
defined by polar coordinates in reference to a pole. See
Subsection 6.5.6.
