Amount of X-axial retreat from the approach point for TOOL EYE measurement

Q: What does Mazak parameter L78 do?

L78 is a Machine parameter in the TABLE group of the MAZATROL SmoothX control (INTEGREX e-670H). Amount of X-axial retreat from the approach point for TOOL EYE measurement. In the machine configuration that will cause the arm of the TOOL EYE to interfere with the tool when the arm is extended or retracted with the tool present at the measuring approach point during automatic tool measurement with the TOOL EYE, set the distance through which the tool is to be returned in the X-axis direction before extending or retracting the arm for the measurement. In the MAZATROL program, before the arm is extended or retracted, the tool is returned through the L28/L78-set distance from the measuring approach point. In the EIA/ISO program, when G136 command execution is completed, the tool will be returned through the L28/L78-set distance from the approach point. (In the EIA/ISO program, the tool will be retreated to a relay point, only in retraction mode, and the arm will be extended by execution of M284 in the next block onward.) X In case of #2, #4 approaching (QTN) TOOL EYE #1, #2 APK1

Machine-specific. This parameter list is specific to the Mazak INTEGREX e-670H / e-670H-S with the MAZATROL SmoothX control (manual HA64HA0035E). Other Mazak models and control generations use different addresses, ranges and meanings — verify on your own control before changing anything.
