Availability
For SINUMERIK 828D, the "toolholder with orientation capability" function is only available for
the milling versions.
Required data
The following requirements must be met if the control is to take tool compensations into account
for toolholders with orientation capability:
● Tool data (geometry, wear, etc.)
● Toolholder data (data for the geometry of the toolholder with orientation capability)
Toolholder selection
A toolholder defined in the control must be specified for the "Toolholder with orientation
capability" function. The NC program command below is used for this purpose:
TCARR = m
m: Number of the toolholder
The toolholder has an associated toolholder data block that describes its geometry.
Activating the toolholder and its block has an immediate effect, i.e. from the next traversing
block onwards.
Assignment tool/toolholder
The tool that was active previously is assigned to the new toolholder.
From the point of view of the control, toolholder number m and tool number T can be combined
freely. In the real application, however, certain combinations can be ruled out for machining
or mechanical reasons. The control does not check whether the combinations make sense.
Description of the kinematics of the toolholder
The kinematics of the toolholder with orientation capability is described with a total of 33
parameter sets.
The data of the data block can be edited by the user.
