Embodiment Construction

[0021] below, with Figure 1 Together, the embodiments of the present invention will be described.

[0022] figure 1 It is a schematic hardware configuration diagram showing main parts of the control device of the first embodiment. The control device 1 can be implemented, for example, as a control device for controlling a servo press. In addition, the control device 1 can be implemented, for example, as a personal computer attached to a control device controlling a servo press, a unit computer connected to the control device via a wired / wireless network, a host computer, an edge server, a cloud server, or other computers. In this embodiment, an example is shown in which the control device 1 is incorporated as a control device for controlling a servo press machine.

[0023] The CPU 11 included in the control device 1 of the present embodiment is a processor that controls the control device 1 as a whole. CPU11 reads the system program stored in ROM12 via bus 20, and controls...

Abstract

The invention relates to a control device and a machine learning device. A machine learning device included in a control device includes: a state observation section for observing control command datarepresenting a control command for a servo press and control feedback data representing feedback for control as a state variable representing a current environmental state; a determination data acquisition section for acquiring workpiece quality determination data for determining the quality of a workpiece machined based on the control command for the servo press and cycle time determination datafor determining the time taken to machine the workpiece as determination data representing a result of determination regarding the machining of the workpiece; and a learning section for learning thecontrol command for the servo press in relation to the feedback for controlling the servo press.

Description

technical field [0001] The invention relates to a control device and a machine learning device. Background technique [0002] In a press machine (servo press machine) using a servo motor for axis control, the same command value (position command value, speed command value, pressure command value, torque command value, etc.) is supplied to the servo motor every cycle from the control device , thereby controlling the position and speed of the slider with high precision and driving up and down to process the workpiece (for example, Japanese Patent Laid-Open No. 2004-17098). [0003] In the servo press machine, even if the command value for the servo motor is the same value every cycle, due to the mechanical state of the servo press machine (accumulation of damage to the metal mold, etc.), or in the case of a punch press, the mechanical External factors such as vibration (hammering buffer) caused by impact, sometimes the same result cannot be obtained every cycle. For example, ...
