Contour transition elements
As a transition between two contour elements, you can choose a radius or a chamfer. The
transition element is always attached at the end of a contour element. The contour transition
element is selected in the parameter screen of the respective contour element.
You can use a contour transition element whenever there is an intersection between two
successive elements which can be calculated from the input values. Otherwise you must use
the straight/circle contour elements.
The contour end is an exception. Although there is no intersection to another element, you
can still define a radius or a chamfer as a transition element for the blank.
The following additional functions are available for programming a contour:
● Tangent to preceding element
You can program the transition to the preceding element as tangent.
● Dialog box selection
If two different possible contours result from the parameters entered thus far, one of the
options must be selected.
● Close contour
From the actual position, you can close the contour with a straight line to the starting
point.
Procedure for entering or changing contour elements
The part program or ShopTurn program to be executed is created.
Select the file type (MPF or SPF), enter the desired name of the pr
o-
"OK" softkey or the "Input" key.
Select a contour element via softkey.
The input window "Straight (e.g. X)" opens.
The input window "Straight (e
.g. Y)" opens.
The input window "Straight (e.g. XY)" opens.
