4.2 Tool Data

T-Codes, and Tool Activation

To activate a tool, program a T-Code followed by the tool number. The tool number corresponds to the row number in the Tool Table. A program tool call example starts with a “T”, followed by the tool number, e.g. “T1”.

Activating Offsets via the Program

In a program, T1 (by itself) calls the Tool Table diameter and length offsets for the specified tool. T1 with D, R, and L address words programs a temporary diameter/radius and length offset independent of the Tool Table. The entered D (diameter) or R (radius) and L (tool-length) offsets remain active until you cancel the active tool.

T1 Format		Description
T1		Activates Tool #1 diameter offset listed
		in the Tool Table.
T1	D.5000 L-1.2500	Applies a diameter offset of .5000 and
		length offset of -1.2500 to the active
		tool.
T1	R.2500 L-1.2500	Applies a tool radius value of .2500 and
		length offset of -1.2500 to the active
		tool.

The diameter offset takes effect when you program Left (G41) or Right (G42). All dimensions are in reference to the work surface.

If you use T1 to activate a tool later in the program, the Tool Table offsets for Tool #1 are used (not the values programmed via T1 Dn/Rn Ln).

It is recommended that you use the Tool Table to avoid confusion or possible entry errors on the offsets.
