A machine tool and a control device therefor, wherein vibration cutting of a workpiece is carried out by means of a tool and wherein, after the vibration cutting, finish-cutting is carried out for cutting a finishing allowance of the workpiece by means of the tool, without relative vibration between the workpiece and the tool, by relatively rotating the workpiece and the tool and relatively moving them in the feed direction. According to the invention, before the vibration cutting, a finishing allowance calculation means calculates a finishing allowance remaining on the workpiece after vibration cutting has been completed, and a determination means determines whether or not the finishing allowance as calculated by the finishing allowance calculation means is less than, or equal to a predetermined threshold value.

A machining program editing assist apparatus includes a display controller. When a specific portion on a shape display area is designated via an input device, the display controller allows a display candidate specified by the specific portion to be displayed as a designated display target of the shape display area, and allows at least one portion of data being among at least one display candidate of a program data display area and sectioned by a machining process constituting the at least one machining process and corresponding to the designated display target of the shape display area to be displayed as a designated display target of the program data display area on the program data display area in a state in which a beginning of the at least one portion of data is set to a display start position of the program data display area.

In a component mounting system having an inspection device performing a mounting inspection after component mounting, a correction value for correcting a mounting program is calculated based on board inspection information including fed-back component position deviation information, a component is mounted on a board in accordance with the mounting program corrected based on the calculated correction value, and a present value based on most recent board inspection information and a pre-correction evaluation value are displayed together on an evaluation value display screen as evaluation values representing accuracy at a time of the mounting based on the board inspection information during this component mounting work, the pre-correction evaluation value being calculated based on a temporary position deviation amount pertaining to a case where it is assumed that no correction based on the calculated correction value has been performed.

The invention relates to a method for the simplified modification of application programs (2<sb/>, 3<sb/>) of an industrial plant (1<sb/>), comprising the following steps: (a) providing at least one application program (2<sb />, 3<sb/>) in an industrial plant (1), wherein the at least one application program (2<sb/>3<sb/>) has a plurality of program points (P1 to P5<sb />); (b) providing at least one graphical representation (101<sb/> to 103<sb/>), wherein the at least one graphical representation (101<sb /> to 103</>) shows at least one system state of the industrial plant (1<sb/>), wherein the system state corresponds to a program point (P1 to P5<sb/>) and the graphical representation (101 to 103) is linked to at least one program point (P1<sb/> to P5<sb/>) of the at least one application program (2<sb/>, 3<sb/>); (c) executing the application program (2<sb/>, 3<sb/>) and, if the application program stops, performing the fo11owing steps: (d) comparing the current system state of the industrial plant (1<sb/>) with the at least one graphical representation (101<sb/> to 103<sb/>) and (e) following a link between the graphical representation and a program point in order to modify the application program.

A numerical controller generates a machining cycle, and controls a machine tool by executing the machining cycle. A block to be corrected is selected from among a plurality of blocks of the machining cycle, the selected block is corrected, and correction information of the block is generated based on the correction and stored. Then, the machining cycle is generated based on the correction information of the stored block and the machining cycle is executed.

A method of path planning via a collaborative robot system is provided. The method includes programming a first welding path along a first welding seam of a first part of a sequence of multiple identical parts to be welded by a user moving a welding torch along the first welding seam to define a first weld pattern. The user positions the welding torch at a start position of the first part and an end position of a last part of the sequence which are recorded. The user informs the system of the number of parts in the sequence. The system calculates a welding path for each part based on the start position, the end position, the number of parts, and the first welding path, thus defining a weld pattern for each part. The system automatically records each weld pattern independently, each of which can be independently modified by the user.

An NC program generating and editing apparatus 2 includes an interactive input module 9, a first memory 10, an NC program generator 11, a second memory 12, a program editor 13, a change checker 14 and a data updater 15. The change checker 14 determines whether a changed portion of an edited NC program consists of only a change related to a preset NC code, and when the changed portion consists of only a change related to the NC code, corresponding basic data is updated by the data updater 15.

A method for moving along a predetermined path with a robot in an at least a partially automated manner includes determining a deployment position on a current path section of the predetermined path for which a distance parameter satisfies a predetermined condition, and moving to the deployment position with the robot. In one aspect, the robot may be moved to the deployment position if a deployment condition is satisfied. The distance parameter may be determined on the basis of a distance of a current position of the robot relative to the current path section. The predetermined condition may be that the distance parameter has a value that is less than or equal to the values of the distance parameter of all positions in a partial area of the current path section, which is in particular complementary to the deployment position.

A machining program management apparatus is used for managing an alteration made to a machining program stored in a plurality of machine tools. The machining program management apparatus acquires, at predetermined intervals set in advance, a piece of machining program updating information including a last update date and time of the machining program stored in each machine tool, identifies a machining program to which an alteration is made, on the basis of the piece of machining program updating information, creates a piece of information on the alteration, and updates a piece of machining program information corresponding to the machining program to which the alteration is made.

A manufacturing action is performed on a first part or first component involved in a manufacturing process. The manufacturing action is directed by computer software that is stored in a memory and executed by a processor. The first part or first component is examined to determine results of the manufacturing action. Based upon the results, a structure of the computer software is selectively changed to optimize the results. Subsequently the manufacturing action is performed on a second part or second component. The manufacturing action is directed by the computer software having the changed structure.
