INDUSTRIAL INSTRUMENT AND MACHINE TOOL
First Claim
1. An industrial instrument performing position control of a movable body moving along a first axis, and rotational speed control of a rotating body rotating about a second axis, comprising:
- a manual pulse generator,a selector switch for selecting manually one of a plurality of axes including said first axis and said second axis, anda control device,said manual pulse generator includinga rotary handle configured to be rotated by hand, anda first signal generator configured to generate a pulse signal based on rotation of said rotary handle, and transmit the generated pulse signal to said control device,said selector switch including a second signal generator configured to generate a signal corresponding to the selected axis,said second signal generator transmitting a signal corresponding to the selected axis to said control device,said control device includinga first determination unit configured to determine an amount of rotation, rotational speed, and direction of rotation of said rotary handle, based on said pulse signal, anda second determination unit configured to determine which of said position control and said rotational speed control is selected by selection of an axis through said selector switch, based on the signal generated by said second signal generator,said control device controllingwhen a determination is made that said position control is selected, an amount and direction of travel of said movable body based on the amount of rotation and direction of rotation of said rotary handle, andwhen a determination is made that said rotational speed control is selected, the rotational speed and direction of rotation of said rotating body based on the rotational speed and direction of rotation of said rotary handle.

Abstract
A control device of a machine tool includes a first determination unit determining an amount of rotation, rotational speed, and direction of rotation of a rotary handle based on a pulse signal generated by rotation of the rotary handle at a manual pulse generator, and a second determination unit determining which of position control and rotational speed control is selected by selection of an axis through an axis selector switch, based on a signal generated by an axis selection signal generator at an operation device including the manual pulse generator. When a determination is made that position control is selected, the control device controls the amount and direction of travel of a spindle based on the amount of rotation and direction of rotation of the rotary handle. When a determination is made that rotational speed control is selected, the control device controls the rotational speed and direction of rotation of a table based on the rotational speed and direction of rotation of the rotary handle. Accordingly, the user can readily set the direction of rotation and rotational speed of the table using the manual pulse generator, and cause the table to move at the set direction of rotation and rotational speed.
