BARRIER bit settings (8 bits)
- bit 0

- bit 1
Method of automatic determination of the virtual nose point for a tool measuring unit
Method of automatic determination of the virtual nose point for tool measuring unit (TOOL EYE) 0: Determined according to the machining section, direction of rotation and orientation (left/right hand) in the tool data * If measurement is carried out at a B-axis angle other than that used for actual machining, the measurement result will not be correct because the virtual nose point that is automatically determined for measurement according to the machining section, direction of rotation and orientation (left/right hand) of the tool will not agree with the virtual nose point of the actual tool. Example: Correct Incorrect Machining section: O.D. Left hand Tool nose point Tool nose points agree 1: Determined from the measurement pattern (TOOL EYE #1 to #4) * The measurement result will not be correct if the virtual nose point that is automatically determined for measurement (with TOOL EYE) from the measurement pattern does not agree with the virtual nose point that is automatically determined according to the machining section, direction of rotation and orientation (left/right hand) of the tool. Example: Correct Correct Machining section: O.D. Left hand Tool nosepoint Tool nose points agree
- bit 2
Display of THRUST F. and HORSE PW for the AFC function in the first set of tool data (BA43, BA44)
Display of THRUST F. and HORSE PW for the AFC function in the first set of tool data (BA43, BA44) 0: Valid 1: Invalid
- bit 3
Display of THRUST F. and HORSE PW for the AFC function in the second set of tool data (BA45, BA46)
Display of THRUST F. and HORSE PW for the AFC function in the second set of tool data (BA45, BA46) 0: Valid 1: Invalid

0: Approach from the approach relay point (APK2) for TOOL EYE #2, #4 1: Approach from the approach relay point (APK1) for TOOL EYE #2, #4 <When bit 4 of parameter is set to 0> * The areas enclosed with dotted lines show approaches to TOOL EYE #2/#4. <Upper turret SP1> <Upper turret SP2> APK2 L78 AP4 <Lower turret SP1> <Lower turret SP2> L78 APK2 APK2 AP1: TOOL EYE #1 approach point, APK1: TOOL EYE #1/#3 approach relay point AP3: TOOL EYE #3 approach point AP2: TOOL EYE #2 approach point, APK2: TOOL EYE #2/#4 approach relay point AP4: TOOL EYE #4 approach point <When bit 4 of parameter is set to 1> * The areas enclosed with dotted lines show approaches to TOOL EYE #1/#2/#3/#4. <Upper turret SP1> <Upper turret SP2> <Lower turret SP1> <Lower turret SP2> AP1: TOOL EYE #1/#2 approach point AP3: TOOL EYE #3/#4 approach point APK1: TOOL EYE #1/#2/#3/#4 approach relay point Related parameters L28: Amount of Z-axial retreat from the approach point for TOOL EYE measurement L78: Amount of X-axial retreat from the approach point for TOOL EYE measurement to SU121: Tool change position during TOOL EYE measurement (bit 0): Tool change position during TOOL EYE measurement
- bit 5
Hobbing on the machine without tool rotary axis or table tilt axis
Action to take when hobbing (G114.3) is specified on a machine not equipped with a tool rotary axis or table tilt axis 0: Alarm stop (alarm 807 ILLEGAL FORMAT) 1: Hobbing Note : If parameter bit 5 is set to 1 with a machine equipped with the tool rotary axis or table title axis, feed commands for the B- or A-axis will not be output when machining helical gears.
- bit 6

0: Invalid 1: Valid
- bit 7
Display of [TURRET UNCLAMP] for machines with an ATC-type turret
Display of [TURRET UNCLAMP] for machines with an ATC-type turret 0: Invalid 1: Valid Note : Setting of bit 7 is valid only for machines without lower turret.
