position measured by the command, and decelerates and temporarily stop the position before the
measured position, and then, reaches to the measured position at the speed set by No.141. When
the measured position arrival signal corresponding to G command becomes “1”, and the tool is in the
measured position range ±
ε
, CNC updates the offset compensation value and ends the block. When
the measured position arrival signal does not become “1”, and after the tool reaches the measured
position distance
ε
, the CNC alarms, ends the block and does not update the offset compensation
value.
3.17.2 Parameters Relevant to G36, G37: Refer to INSTALLATION,
Section 3.2.16.
3.17.3 G36, G37 Automatic Tool Offset Command Use
Feedrate and alarm
From the initial position to the measured position specified by Xa or Za in G36 or G37, the tool
rapidly traverses to A zone and stops at T point (Xa–
γ
x or Za–
γ
z) , and then traverses to B, C and D
at the feedrate set by No.141. The system alarms when the tool traverses in B zone and the
measured point arrival signal of the end point is set to. CNC alarms when the tool stops at V point.
Example:
G50 X760 Z1100; create the workpiece coordinate system
T0101;
define No. 1 tool and execute its tool compensation
