Abstract
A machine tool controlled by a numerical controller includes a feed handle for driving a drive-shaft for moving a tool and a workpiece relatively by using a mechanical mechanism and a motor for driving the drive shaft. The numerical controller generates an automatic feed command for driving the motor when a specific handle operation performed on the feed handle is detected.

A numerical controller controlling a machine tool by generating an automatic feed command for driving a motor, the machine tool including a drive shaft for moving a tool and a workpiece relatively, a feed handle for driving the drive shaft by using a mechanical mechanism, and the motor for driving the drive shaft,
- the numerical controller comprising a processor configured to:
- detect a first specific handle operation performed on the feed handle while the numerical controller is operating in a manual feed state for driving the drive shaft;
- in response to detecting the first specific handle operation, switch to an automatic feed state for driving the drive shaft and output the automatic feed command;
- detect a second specific handle operation performed on the feed handle while the numerical controller is operating in the automatic feed state;
- and
- in response to detecting the second specific handle operation, switch to the manual feed state.
A numerical controller controlling a machine tool by generating an automatic feed command for driving a motor, the machine tool including a drive shaft for moving a tool and a workpiece relatively, a manual pulse generator that generates a manual feed command on the basis of a rotation amount of a handle, and the motor for driving the drive shaft according to the manual feed command,
- the numerical controller comprising a processor configured to:
- detect a first specific handle operation performed on the manual pulse generator while the numerical controller is operating in a manual feed state for driving the drive shaft;
- in response to detecting the first specific handle operation, switch to an automatic feed state for driving the drive shaft and output the automatic feed command when the specific handle operation is detected;
- detect a second specific handle operation performed on the manual pulse generator while the numerical controller is operating in the automatic feed state;
- and
- in response to detecting the second specific handle operation, switch to the manual feed state.
