摘要： The numerical controller has a program restart function and acquires program restart block data for resuming and ending suspended machining of a workpiece. The numerical controller analyzes a block of a machining program, and upon determining that a moving path of a tool, which is determined by the block, passes a boundary of a predetermined machining area of each controlled axis of a machine tool, the numerical controller acquires the program restart block data of that block and performs partial machining of the workpiece based on the acquired program restart block data.

摘要： A numerical control device that controls servomotors configured to process a workpiece into an arbitrary finishing shape by performing a plurality of processing operations so that the tool moves along a processing locus, the numeral control device includes: an initial locus deriving unit configured to derive the processing locus based on the arbitrary finishing shape; a processed range acquiring unit configured to acquire a processed range in which the tool has performed the processing operation; a receiving unit configured to receive a processing instruction for a changed finishing shape different from the arbitrary finishing shape; and a changed locus deriving unit configured to derive a changed processing locus based on a shape of a changed processed part obtained by excluding the processed range from the changed finishing shape at the time of interruption of the processing.

摘要： A numerical control device is intended for a machine tool that machines a workpiece using a multi-edge tool including a plurality of edges of different specifications, the numerical control device including: a tool information memory that stores edge type numbers in association with tool type numbers; a tool type-edge type selection command decoding unit that prefetches a plurality of blocks of a machining program, decodes a tool type selection command for selecting one of the tool types and/or an edge type selection command for selecting one of the edge types in the plurality of prefetched blocks, and generates internal information including the tool type selection command and/or the edge type selection command that have been decoded; and a tool selection unit that selects one tool with which the number of times of tool replacement is minimized during execution of at least the plurality of prefetched blocks.

摘要： A numerical controller has a threading cycle function that performs threading on a workpiece by repeating an operation in which a tool is positioned at a cutting start position based on a machining program designating a thread shape and is relatively moved in the workpiece axis direction with respect to the workpiece. By a threading instruction of the machining program, a cutting start position for each cycle is calculated so that the workpiece is sequentially cut in a direction opposite to the movement direction of the tool with respect to the workpiece. The tool is positioned at the cutting start position calculated for each cycle and the threading is performed on the workpiece.
