Problems solved by technology

[0004] However, in the device described in Japanese Patent Application Laid-Open No. 2013-182604, it is necessary to construct in advance a complex system for predicting the pressure on the driven part from the current applied to the driving part, etc., based on, for example, a dual-inertia system control model. model of
Such model building is very complex and difficult

Embodiment Construction

[0031] A configuration example of a numerical controller according to an embodiment of the present invention is shown below. However, the configuration of the numerical controller of the present invention is not limited to the following examples, and any configuration can be adopted as long as the object of the present invention can be achieved.

[0032] Figure 8 An example of a machine control system using a pressure sensor is shown. In this example, control is performed based on feedback from a pressure sensor so that the pressure is maintained at an appropriate value.

[0033] Also in the embodiment of the present invention, while the numerical controller 10 is in the learning phase, control using the pressure sensor is performed as in the past. However, in the presumptive stage after the end of study, if Figure 9 As shown, pressure control without a pressure sensor is possible. That is, the numerical controller 10 in the estimation stage performs pressure control usin...

Abstract

Provided is a numerical controller capable of easily controlling a pressure without a pressure sensor. The numerical controller estimates a pressure based on at least one of a command value and a feedback value. A machine learning device for learning the pressure corresponding to the at least one of the command value and the feedback value is included. The machine learning device includes a stateobservation unit for observing the at least one of the command value and the feedback value as a state variable, a label data acquisition unit for acquiring label data indicating the pressure, and a learning unit for associating and learning the state variable with the label data.

Description

technical field [0001] The invention relates to a numerical control device, in particular to a numerical control device capable of pressure control without a pressure sensor. Background technique [0002] Currently, in machines such as injection molding machines and press machines, which operate a contact object by a servo motor or the like and apply force to the object to be contacted, a pressure sensor is used in order to detect the force acting on the object to be contacted (see Figure 8 ). In order to use the pressure sensor, in addition to the cost of the pressure sensor itself, work such as installing a strain gauge at the detection position also takes a corresponding amount of man-hours. [0003] Regarding this point, Japanese Patent Application Laid-Open No. 2013-182604 describes a device that predicts a driven part (equivalent to the above-mentioned The pressure on the contacted object). [0004] However, in the device described in Japanese Patent Application Lai...
