A machining apparatus is provided with a machine learning device that performs machine learning. The machine learning device performs the machine learning by receiving the input of machining accuracy between a machining shape of a workpiece measured on-machine and design data on the workpiece and machining time of the workpiece measured by a measurement device. Based on a result of the machine learning, the machining apparatus changes machining conditions such that the machining accuracy increases and the machining time becomes as short as possible.

A data generating device includes a processor, and a memory. The memory is configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes. The processes include acquiring image data representing a pattern, acquiring graphic data representing a graphic, setting a layout relationship between the pattern and the graphic, and acquiring a reference used in position alignment of the pattern and the graphic. The processes include generating processing data that causes a processing device to perform first processing and second processing. The processing device is configured to carry out a process, including cutting, on a sheet-like workpiece. The first processing is processing to form a plurality of first holes designating the graphic by cutting the workpiece. The second processing is processing to carry out a process at a position on the workpiece corresponding to the reference, on the basis of the layout relationship.

A method and system (10) are provided for automatically portioning workpieces (14) using a rotating blade (22) passing through narrow gap (20) formed between the ends of adjacent conveyors (12) and (18). A scanning system (16) scans the workpieces (14) to physically characterize the workpieces and control the operation of the blade (22), including its rotational speed. The portioning of the workpiece can be carried out in accordance with one or more directly-controlled characteristics (parameter/specifications), such as a cutting path of the blade (22), the rotational speed of the blade (22), and the speed of the conveyor (12). The directly-controlled characteristics may be varied until an acceptable set of one or more indirectly-controlled characteristics is achieved, including, for example, the weight of the cut portions, the quality of the cuts achieved by the cutting blade, and the throughput of the portioning system (10).

This control device for controlling an industrial machine using a machining tool comprises: a program execution unit for causing the industrial machine to execute a program that includes a start command for starting a machining process and an end command for ending the machining process by the machining tool; and a counting unit for counting, during execution of the program, the number of times of a completion state indicating that machining abnormality has not occurred in the machining process including the start command and the end command and that each of the commands has been executed and completed.

A system for generating control code for controlling the movements of a CNC machine to form a keyway in a workpiece is provided. The generated control code is calculated using stored dimensions of a tool holder having a unique identifier along with a known position on the tool holder of a cutting tool along with input choices by a user for a length and depth of the keyway on the chosen workpiece. Once generated, the control code is communicated electronically to the user for input to the control software for their CNC machine.

A numerical controller performs PID control to control the move speed of an axis for driving a spindle such that a load value of the spindle becomes constant. When the spindle load value exceeds a threshold value, a speed calculation unit of the numerical controller calculates an override for the feed rate of the axis instructed by command data such that the load value of the spindle becomes constant, and, at the start of the speed calculation process, assigns the override just before the start of the speed calculation process to an initial value of an integral term or an offset for PID control.
