Title: Numerical control device and control method

IPC: G05B19/416
Filed: 2017-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a numerical control device and a control method capable of suppressing overheating while effectively utilizing the output torque of a servo motor.SOLUTION: During tapping operation, a CPU simultaneously drives a main-shaft motor and a Z axis motor. When the temperature of the main-shaft motor is less than an attention threshold (S2: YES), the CPU executes two-stage acceleration/deceleration control of the main-shaft motor and the Z-axis motor (S9) in order to make maximum use of the output torque of a servo motor. In the two-stage acceleration/deceleration control, since the output torque of the servo motor is used to the utmost, the temperature of the main-shaft motor rises when continuous operation is performed. When the temperature of the main-shaft motor is equal to or higher than the attention threshold (S2: NO), the CPU switches from the two-stage acceleration/deceleration control to one-stage acceleration/deceleration control (S10) in order to reduce loading on the main shaft motor. The output torque that can be used in the one-stage acceleration/deceleration control is smaller than the two-stage acceleration/deceleration control. Therefore, the numerical control device can suppress overheating while effectively utilizing the output torque of the servo motor.SELECTED DRAWING: Figure 4

Abstract: To make it possible to appropriately deal with adhesion of a viscous fluid to a discharge tool of a discharge head.SOLUTION: A viscous fluid applicator determines a state of adhesion of a viscous fluid to a discharge tool based on an image which is picked up by an imaging device after the discharge tool has discharged the viscous fluid, and when determining that the viscous fluid of a first prescribed discharge quantity or more is adhered to the discharge tool, so controls a mobile device that a discharge head is moved at a speed lower than a prescribed speed when performing application treatment.
