Setting the cutting linear speed and the workpiece diameter
Setting of cutting linear speed:
Operation procedures:
-
Return to the standard display;
-
Press the
key, the X-axis will display S-U, the Z-axis (the Y-axis for
2-axes positon display) will display the set value of the cutting linear speed;
-
Enter the new set value of the cutting linear speed (unit: mm per second);
-
Press the
key to confirm.
Setting the initial (maximum) work piece diameter:
Operation procedures:
-
Return to the standard display;
-
Press the
key, the X-axis will display S-d, the Z-axis (the Y-axis for
2-axes position display) will display the set value of the initial (maximum) work piece
diamter;
-
Enter the new set value of the initial (maximum) work piece diameter (unit: mm);
-
Press the
key to confirm.
Note: When the value of the current cutter position is greater than the value of the initial
(maximum) work piece diameter, the principal axis will keep the speed value corresponding to
the value of the initial (maximum) work piece diameter set value.
A description of the constant linear speed cutting principle:
N=V / (
π
x
D
)
In the above formula N is the revolution speed of the principal axis; V is the set value of the
cutting linear speed; D is the current value of the work piece diameter, the maximum value
can be selected as the set value of the initial work piece diameter; the X-axis displays the
current value of the work piece diameter (or radius).

the set value of the lower limit of the principal axis low gear speed
200
When the external switch low speed signal is effective the D/A will out-
put the principal axis speed corresponding to 0V.
23
the set value of the upper limit of the principal axis high gear speed
770
When the external switch low speed signal is ineffective, the D/A will out-
put the principal axis speed corresponding to 10V.
24
the set value of the lower limit of the principal axis high gear speed
77
When the external switch low speed signal is ineffective, the D/A will out-
put the principal axis speed corresponding to 0V.
