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.

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 method in accordance with the invention for modification of a robot path which has a plurality of path points comprises the following steps of specifying a modification region which has at least two path points of the robot path, specifying a modification of a reference point of the modification region, and automated modification of the modification region, in particular of path points of the modification region, on the basis of the specified modification.

A numerical control apparatus includes a program storage, a display device, an automatic-operation control unit, a suspending operation unit, a program manipulation unit, and an automatic-operation monitoring unit. The automatic-operation monitoring unit monitors an execution state of the automatic-operation control unit. At a time of resumption of execution of an NC program after suspension of the execution of the NC program by the suspending operation unit, the automatic-operation monitoring unit checks whether a resumption block containing a character designated in the program manipulation unit immediately before the resumption is a preset resumable block or not. When the resumption block is the resumable block, processing in the automatic-operation control unit is resumed from the resumption block, while when the resumption block is not the resumable block, the processing is halted.
