Numerical controller oscillating motion adjustment

A numerical controller which controls an oscillating motion of an oscillation axis of a machine, the numerical controller comprising:

• an oscillating motion data holding unit configured to hold oscillating motion data used for the control of the oscillating motion;
• an oscillating pulse calculation unit configured to calculate oscillating pulses used for the control of the oscillation axis, based on the oscillating motion data held in the oscillating motion data holding unit, and output the calculated oscillating pulses;
• a motor control unit configured to control a motor for driving the oscillation axis, based on the oscillating pulses output from the oscillating pulse calculation unit;
• and
• an oscillating motion data calculation unit configured to:
• determine an oscillating motion adjustment based on a data item related to the oscillating motion, the data item selected based on a state of a switch means on a control panel of the machine,
• wherein in a first state the data item is selected to be an upper boundary-point position of the machine, in a second state the data item is selected to be a lower boundary-point position of the machine, in a third state the data item is selected to be an oscillation width of the machine, and in a fourth state the data item is selected to be an oscillation center position of the machine, and
• change a value of the selected data item to adjust the oscillating motion, based on manual pulses input from a manual pulse generator on the control panel of the machine,
• wherein in the first state the upper-boundary point position of the machine is adjusted based on manual pulses, in the second state the lower boundary-point position of the machine is adjusted based on manual pulses, in a third state the oscillation width of the machine is adjusted based on manual pulses, and in a fourth state the oscillation center position of the machine is adjusted based on manual pulses.
