Description
2.5 Definition of the planes, tool types
Turning machines generally only use axes Z and X and therefore:
G18 plane
Tool type
Length 1
Length 2
G17 and G19 are used for milling on a turning machine. If there is no machine axis Y, milling
can be implemented with the following kinematic transformations.
● TRANSMIT
● TRACYL
In principle, measuring cycles support kinematic transformations. This is stated more clearly
in the individual cycles and measuring variants. Information about kinematic transformation
can be found in the Programming Manual
the documentation of the machine manufacturer.
Note
If a drill or milling cutter is measured on a lathe, in most cases, the channel-specific SD 42950
$SC_TOOL_LENGTH_TYPE = 2 is set: These tools are then length-compensated like a
turning tool.
SINUMERIK controls have other machine and setting data that can influence the calculation
of a tool.
