5. Threading
(1) [Outer surface]:
X = [Maximum outside diameter of the workpiece] +
[Parameter No. 9784]
Z = [End face of the workpiece] + [Parameter No. 9785]
= –[Length of the workpiece] + [Cutting allowance on the end
face] – [Parameter No. 9785] (Sub–spindle)
(2) [Inner surface]:
X = [Minimum inside diameter of the workpiece (or [Maximum
diameter of a hole drilled in the workpiece])] – [Parameter
No. 9784]
Z = [End face of the workpiece] + [Parameter No. 9785]
= –[Length of the workpiece] + [Cutting allowance on the end
face] – [Parameter No. 9785] (Sub–spindle)
6. Grooving and necking
(1) [Outer surface and end face]:
X = [Maximum outside diameter of the workpiece] +
[Parameter No. 9784]
Z = [End face of the workpiece] + [Parameter No. 9785]
= –[Length of the workpiece] + [Cutting allowance on the end
face] – [Parameter No. 9785] (Sub–spindle)
(2) [Inner surface]:
X = [Minimum inside diameter of the workpiece (or [Maximum
diameter of a hole drilled in the workpiece])] – [Parameter
No. 9784]
Z = [End face of the workpiece] + [Parameter No. 9785]
= –[Length of the workpiece] + [Cutting allowance on the end
face] – [Parameter No. 9785] (Sub–spindle)
7. Drilling:
X= 0
Z = [End face of the workpiece] + [Parameter No. 9785]
= –[Length of the workpiece] + [Cutting allowance on the end
face] – [Parameter No. 9785] (Sub–spindle)
8. C–axis drilling:
X = [Maximum outside diameter of the workpiece] +
[Parameter No. 9784]
Z = [End face of the workpiece] + [Parameter No. 9785]
= – [Length of the workpiece]+[Cutting allowance on the end
face] – [Parameter No. 9785] (Sub–spindle)
9786 ZEROPT
ZEROPT 0 : The program reference position is on the end surface of the workpiece.
1 : The program reference position is on the end surface of the chuck.
