3.3 Tool Measurement

By manually moving the tool to the measurement point, the movement distance from the basic point to the
measurement point is measured, and this can be set as the tool compensation amount.
There are two types of tool measurement: Tool length measurement I, Tool length measurement II
Tool length measurement I
When the tool is at the machine coordinate zero point, the distance from the tool tip to the measurement
point (workpiece upper end) is measured, and can be set as tool compensation data.

Tool length measurement II
When the tool is at the machine coordinate zero point, the distance from the machine coordinate zero
point to the tool tip is measured, and can be set as tool compensation data.

(Note) Changing of the tool measurement type is determined based on the measurement axis (tool length
measurement axis, tool radius measurement axis) TLM reference length (parameter " #2016 tlml+ " ) at
each measurement mode. When parameter " #2016 tlml+ " is " 0 " , the tool measurement type is tool
length measurement I.

Using a reference position return, etc., position
the tool at the basic point.
Select the measurement tool.
Turn ON the TLM switch of the machine
operation board.
Using JOG feed, manual handle feed, etc.,
move the tool to the measurement point.
When the measurement is completed, designate
the tool compensation No.
Confirm the value of the operation parameter
"tlml".
When using the gauge block, etc., set the value
of the reference surface height.
Using a reference position return, etc., position
the tool at the basic point.
Select the measurement tool.
Turn ON the TLM switch of the machine
operation board.
Using JOG feed, manual handle feed, etc.,
move the tool to the measurement point.
When the measurement is completed,
designate the tool compensation No.
