14.8 TOOL OFFSETS BASED ON TOOL NUMBERS
Cutter compensation data, tool length compensation data, and the tool
pot number can be set for a specific tool number (T code). Up to 300 sets
of data can be set. If a certain tool number is specified, the pot number
corresponding to that tool number is output as a T code to the PMC. If
cutter compensation or tool length compensation is specified,
compensation is performed using the cutter compensation or tool length
compensation data set for the tool number.
Tool Data Registration, Modification, and Deletion
- Setting tool data
After all the registered tool data has been deleted, programmed tool data
can be registered.
- Adding or modifying tool data
The tool data programmed for a group can be added to or modified. If a
previously registered tool number is specified, the tool data for that tool
number is updated to specified data.
- Deleting tool data
Registered tool data can be deleted. If an attempt is made to delete the
tool data for the currently selected tool, a PS0425 alarm is issued. Any
attempt to delete tool data by specifying a tool number and pot number
fails if no tool matches the two numbers.
Tool Offset Based on Tool Numbers
- Tool pot number output
When a tool number (T code) is specified, the corresponding tool pot
number is read from the tool data file, then is output to the machine as a
tool function code signal (T0 to T31) together with the tool function
strobe signal (TF).
- Compensation based on a cutter compensation value and
tool length compensation value
When an M code for tool change is specified, the cutter compensation
value and tool length compensation value of the previously specified tool
number (T code) become valid. Then, compensation is applied using the
valid compensation values when a compensation command (such as G43
and G41) is executed.
