POINT bit settings (8 bits)
- bit 0
Surface speed calculation for spot drill used
Surface speed calculation for spot drill used 0: Based on machining hole diameter 1: Based on nominal diameter of the tool
- bit 1
Element that determines the counterboring pattern
Element that determines the counterboring pattern (whether to execute diameter enlarging) 0: Determines the counterboring pattern from the nominal diameter in tool data and the hole diameter in the program. 1: Determines the counterboring pattern from the tool diameter in the tool data and the hole diameter in the program.
- bit 2
Setting of the amount of chamfer in the spot drill tool sequence
The amount of chamfer in the spot drill tool sequence 0: Cannot be specified 1: Can be specified
- bit 3
Menu display setting of RGH BCB (inversed faced hole machining), BK-CBORE (back boring) and CBOR-TAP (counterbore tapping), as well as BACKSPOT FACER (inversed spot-facing tool) and BACK BORING BAR (back boring) in the tool sequence data
RGH BCB (inversed faced hole machining), BK-CBORE (back boring), and CBOR-TAP (counterbore tapping) are displayed in the menu in the point-machining unit. BACKSPOT FACER (inversed spot-facing tool) and BACK BORING BAR (back boring) are displayed in the tool menu for tool sequence data in the point-machining unit. 0: Invalid (not displayed) 1: Valid (displayed) * Even if the menu display is disabled, the menu is enabled and displayed in the expert mode, i.e. when the SMART mode is canceled.
- bit 4
Conditions to determine the CIRC MIL operation for the specification without Y-axis
Conditions to determine the CIRC MIL operation for the specification without Y-axis 0: Machining in Cycle 1 HOLE- = Tool diameter 1: Machining in Cycle 1 HOLE- ≥ Tool diameter * For RGH CBORE and CBOR TAP, this parameter is valid when D96 bit 1 = 1 and invalid when D96 bit 1 = 0.
- bit 5
Setting of the start point Y of the cylindrical surface in the C-axis point machining unit
Setting of the start point Y of the cylindrical surface in the C-axis point machining unit 0: Impossible 1: Possible
- bit 6
Smooth chamfering (C-POINT MACH-ING): Switching of the restrictions according to the cutting edge angle of a chamfering tool
Switching of the restrictions according to the cutting edge angle of a chamfering tool used for Smooth chamfering (C-POINT MACH-ING) 0: Enables machining only when the cutting edge angle is 45. (Alarm if the cutting angle edge is not 45.) 1: Enables machining even when the cutting edge angle is not 45. (Conventional scheme)
- bit 7
Cutting depth in deep-hole tapping/high-speed deep-hole tapping cycle
Used to select the mode of operation when the cutting depth is not specified or is set to 0 in the deep-hole tapping or high-speed deep-hole tapping cycle. 0: Perform tapping without pecking 1: Alarm
