(1) Calculation of each point
a : Chuck reference position specified on the
setting screen before execution
b’ : X = GOX + WOX – WSX + H – (W – W1)
Z = Z–coordinate of point a
c : X = GOX + WOX – WSX + H
Z = GOZ + WOZ – WSZ – L’ + L1
d : X = GOX + WOX – WSX + H – (W – W1)
Z = GOZ + WOZ – WSZ – L’ + L1
e’ : X = GOX + WOX – WSX + H – (W – W1)
Z = GOZ + WOZ – WSZ – L’ – (L – L1) –
CL
f’ : X = X–coordinate of point a
Z = GOZ + WOZ – WSZ – L’ – (L – L1) –
CL
g : X = GOX + WOX – WSX + H
Z = GOZ + WOZ – WSZ – L’ – (L – L1) –
CL
GOX : Tool geometry compensation (X)
WOX : Tool wear compensation (X)
WSX : Shift of the X–coordinate in the workpiece
coordinate system (X)
H : Inside diameter of the workpiece
L’ : Workpiece length
GOZ : Tool geometry compensation (Z)
WOZ : Tool wear compensation (Z)
WSZ : Shift of the Z coordinate in the workpiece
coordinate system (Z)
CL : Amount of clearance (100 mm or 10 inches)
L, W, L1, W1 : Dimensions of the chuck
