6.3 Workpiece Description
Basics of contour definition
You program a contour by entering individual
contour elements one after the other in the correct
sequence.
You can define the contour elements/contour
position using absolute, incremental, Cartesian or
polar coordinates. You can usually program a
contour with the dimensions given in the
workpiece drawing.
X values are entered as diameter or radius values
(see “
6.14 Configuration”).
TURN PLUS 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.
Importing contours in DXF format
Contours available in DXF format can be imported into the TURN
PLUS programming mode of operation (see “
6.8 Importing DXF
Contours“).
DXF contours describe
■ Workpiece blanks
■ Finished parts
■ Contour train
■ Milling contours
