A machining program editing assist device includes a CAD data analysis unit which analyzes CAD data of a workpiece after a change, and acquires CAD shape information about the workpiece after the change, and a machining program analysis unit which analyzes a machining program before the change, and acquires machining shape information about the workpiece before the change. The device also includes an input shape prediction unit which acquires predicted shape information by performing shape matching between the CAD shape information and the machining shape information before the change, and specifying a modified shape, and an NC program auto-generation unit which, based on the predicted shape information, inserts a machining route that is existing only in the CAD data into the machining program, and deletes a machining route that is present only in the machining program from the machining program.

A device displays contents of data used by an electronic component mounting machine. The data includes necessity information regarding a plurality of optional functions. The optional functions are functions which are selectively used among the functions of the electronic component mounting machine, and the necessity information is information which describes necessity of use of each of optional functions. The device includes an extraction processing section and a display section. The extraction processing section extracts the necessity information regarding a plurality of optional functions from the data used by the electronic component mounting machine. The display section visually displays the necessity information regarding the plurality of optional functions extracted by the extraction processing section.

Movement commands in a sequence of movement commands each define a position to be adopted by a tool of a processing machine relative to a workpiece. During the execution of the sequence of movement commands by a control device of the processing machine, the tool machines the workpiece at least intermittently. The movement commands, during their execution by the control device of the processing machine, are converted into a trajectory including the defined positions. A depiction of the trajectory defined by the sequence of movement commands is output to a user. The distances between the positions of directly successive movement commands are ascertained. Positions of directly successive movement commands whose distance is below a predetermined minimum distance are highlighted in the depiction by means of a marker.

A matching recognition method for an NC program and corresponding cutting tools includes a step of using an imaging device to capture 2-dimensional images from the cutting tools mounted at the corresponding numbered tool holders on a machine tool, a step of based on the 2-dimensional images to extract outline feature points and assembling postures of cutting tools and converting into corresponding tool-assembling strings, a step of obtaining tool demands from each of the sequential machining steps in the NC program and converting into corresponding stepwise tool-demanding strings, and a step of performing matching upon the tool-assembling strings and the stepwise tool-demanding strings to generate and output corresponding step-and-tool matching strings. In addition, an associated matching recognition system is provided to include an imaging device, an image-processing module, a step-decoding module and a matching and comparing module.

A numerical control device includes: a command analysis unit that analyzes a processing program which includes, in one block, a first command including a numerical value defining shaft operation, a second command including any of a preparation function command, a speed command, a main shaft rotation command, a tool exchange command, and an auxiliary command, and a third command defining the execution timing of the second command; and a command information generation unit that generates command information of the second command on the basis of the first command and the third command which have been analyzed by the command analysis unit.

This disclosure concerns a method for selecting a tool-path strategy in a material processing operation. The geometry of a work piece (34) and the contact patch (36) of a tool are determined and used to define a tool-path boundary (30,32). A number of different possible tool-paths (38,40,46) are then simulated within the tool-path boundary (30) and the most preferred tool-path (38,40,46) is selected based on predefined requirements.

An interference determination method for machine tools which determines whether or not there will be interference between elements that move relative to each other, the method including: a setting procedure for setting a machine tool model obtained by combining the shape model of each of the elements including a work model corresponding to the work; a measurement procedure for measuring the position of the work attached to the work attachment part; a correction procedure for acquiring, at a predetermined timing, the position of the work measured in the measurement procedure, and correcting the machine tool model set in the setting procedure; and a determination procedure for determining whether or not there will be interference between the elements on the basis of the machine tool model corrected in the correction procedure.
