● Guiding grooves:
TRACYL does not create the same groove for guiding grooves as it would be with a tool with the diameter producing the
width of the groove. It is basically not possible to create the same groove side geometry with a smaller cylindrical tool as
it is with a larger one. TRACYL minimizes the error. To avoid problems of accuracy, the tool radius should only be slightly
smaller than half the groove width.
Note
OFFN and TRC
With TRAFO_TYPE_n = 512, the value is effective under OFFN as an allowance for TRC. With TRAFO_TYPE_n = 513, half
the groove width is programmed in OFFN. The contour is retracted with OFFN-TRC.
Linear interpolation
8.3.1
Linear interpolation with rapid traverse: G0
Functionality
The rapid traverse movement G0 is used for rapid positioning of the tool, but not for
direct workpiece machining
.
All the axes can be traversed simultaneously - on a straight path.
For each axis, the maximum speed (rapid traverse) is defined in machine data. If only one axis traverses, it uses its rapid
traverse. If two or three axes are traversed simultaneously, the path velocity (e.g. the resulting velocity at the tool tip) must
be selected such that the
maximum possible path velocity
with consideration of all axes involved results.
A programmed feedrate (F word) has no meaning for G0. G0 remains active until canceled by another instruction from this G
group (G1, G2, G3...).
G0 X... Y... Z... ; Cartesian coordinates
G0 AP=... RP=... ; Polar coordinates
G0 AP=... RP=... Z... ; Cylindrical coordinates (3dimensional)
Another option for linear programming is available with the angle specification ANG=... (For more information, see Section
"Contour definition programming (Page 88)".).
