Methods for configuring laser machining machines (1) include control (2), whereby different types laser machining processes (A, B, C, D) can be executed using the laser machine (1), these processes being respectively controlled by the control apparatus (2) using process parameters. The processes of different types are categorized in a classification (20), in which a respective set of process parameters (21A-24A; 21B-24B; 21C-24C; 22D-24D), that are used during the execution of the respective process (A, B, C, D), is assigned to each process. During a determination and/or changing of a first process parameter (21A-24A) of a first process (A), a process parameter (S1-S6; 21B-24B; 21C-24C; 22D-24D) of a different process (B, C, D) that is contained within classification (20), is automatically determined and/or changed according to a stored rule, as a function of the first process parameter.

A machining system includes a cover body having an opening and defining a machining area of a workpiece, a door portion provided in the opening, an actuator that operates the door portion between a first position at which the opening is closed and a second position at which the opening is opened, a controller that controls the actuator, and a robot arm that operates through the opening to convey a workpiece between the machining area and an external area outside the machining area. The controller controls the actuator such that the door portion is positioned at a third position when the robot arm conveys the workpiece. An opening area of the opening when the door portion is positioned at the third position is smaller than an opening area of the opening when the door portion is positioned at the second position.

A numerical controller according to the present invention stores comparative relationship between parameters related to setting of the numerical controller, extracts data having comparative relationship among parameters related to the setting of the numerical controller based on the stored comparative relationship, and causes a display to display the data having the comparative relationship in association with each other.

Various embodiments of the teachings herein include a method for subtractive machining of a workpiece using a tool. The method may include: detecting at least two process variables of a machining process; and using the process variables to infer a wear on the tool. The process variables are passed on to a neural network which assigns each process variable a respective degree of wear independently of the other. The wear is inferred by means of a logic on the basis of the respective degrees of wear. The process variables are each selected from the group consisting of: a shape of the tool, an operating current, an operating voltage, maintenance and servicing information, and interruption information of the machining. Detecting the shape of the tool includes imaging using a camera and/or a scanner.

To provide a control system of a machine tool that enables a changed parameter to be reflected to a machine side in an arbitrary timing according to a worker's intention. A control system of a machine tool automated by reflecting a parameter by computerized numerical control, includes a storage unit that, when the parameter is changed, stores the parameter thus changed as a changed parameter, a changed parameter reflection condition setting unit that sets a condition for reflecting the changed parameter, and a changed parameter reflection unit that, when the condition is detected, reflects the changed parameter not yet reflected.

A machining center processes a section not to be corrected of a workpiece and a crankshaft bearing hole in a different position from the section not to be corrected and which is separated from an upper deck surface of the workpiece. The machining center supplies a coolant to the hole during processing and detects a temperature of the coolant. A control apparatus estimates the temperature of the coolant when a predetermined time elapses from a start of the processing to be a temperature of the workpiece, calculates a deformation amount of the workpiece due to thermal expansion, corrects a position of the hole with respect to the upper deck surface based on the deformation amount, and starts processing of the hole after the predetermined time. The predetermined time ends when a difference between a temperature near the hole and the temperature of the coolant falls within a predetermined range.

A confirmation method for a tool of a machining process, applied to detect a health status of a tool changing device, includes following steps: obtaining tool data of a processing equipment from a storage unit of the tool through a first wireless transmission module; interpreting tool data, and converting an interpreting result into a tool assembling status data string; interpreting a tool acquirement corresponding to a process of a processing program, and converting the interpreting result into a process-related tool acquirement data string; and, comparing the tool assembling status data string with the process-related tool acquirement data string, and outputting a program and tool matching data string. In addition, a system for confirming a tool of a machining process is also provided.
