(Example 2) If the spindle-to-detector gear ratio is changed to 2/3
in the above example (three spindle rotations for two detector
rotations)
In this case, the number of pulses per spindle rotation is:
×
There is a remainder. In this case, change the setting of parameter
No. 5997 so that the ratio between parameter No. 5996 and No.
5997 becomes the desired value.
×
Therefore, it is only necessary to set No. 5996 = 160000 and No.
5997 = 1080000.
With this method, stress is placed on the correct ratio between the
two parameters. So the value of the ratio can be reduced, and the
resulting numerator and denominator can be set as the respective
parameters. In this case, it is possible to set No. 5996 = 16 and No.
5997 = 108.
If the ratio between the number of pulses for the master axis and
that for the slave axis is adjusted, but the actual number of pulses
does not match the corresponding parameter (for example, if the
ratio is modified because the number of pulses is indivisible
because of a gear ratio between the master and slave axes, as in
example 2), it is impossible to specify the following G81.5
commands.
G81.5 T_ C_: If a number of rotations is specified for the master
axis, and an amount of travel is specified for the slave axis
G81.5 P_ C0 L_: If a number of pulses is specified for the master
axis, and a number of rotations is specified for the slave axis
G81.5 X_ C0 L_: If an amount of travel is specified for the master
axis, and a number of rotations is specified for the slave axis
