Form-Truing (Cycle495) - Siemens SINUMERIK 840D sl Operating Manual

Sequence
In the cycle, the tool data of the tool that is not active is transferred into the cycle frame. This
means that the dressing contour can be subsequently called relative to the geometry
parameters.
After machining the dressing contour, the cycle frame is cleared by calling the cycle without
transfer parameter.
Example
T="WHEEL"D1
CYCLE435(„WHEEL",1,"DRESSER",1,0.01,0.01,10,10,0,0,0)
G01 G64 F200
X=10
Z=10

CYCLE435()
In the example, after the cycle, the "DRESSER" tool with cutting edge 1 is active.
Internally, an offset of 0.01 mm is taken into account in X and Z (for G18) and the contour itself
is offset by 10 mm, so that workpiece drawing dimensions can be programmed. A form-truing
allowance that can be taken into account is 0. After this, the dressing contour can be machined.
After machining, the cycle frame is cleared by calling CYCLE435() without transfer parameter.
