20080294877 | NUMERICAL CONTROLLER HAVING FUNCTION OF RESUMING LOOK-AHEAD OF BLOCK - A numerical controller which performs look-ahead control by suspending analysis of a read block of a machining program and resuming the analysis of the read block at a suspended stage when execution of a block immediately preceding the read block is completed. The numerical controller successively reads and analyzes blocks of the machining program in advance, stores the analyzed blocks into a buffer, and then executes the stored blocks, and comprises means for determining whether or not a read block contains a look-ahead stop code to suspend analysis of the block, means for suspending the analysis of the block when the look-ahead stop code is determined, means for determining whether or not execution of a block immediately preceding the suspended block is completed, and resuming means for resuming the analysis of the suspended block when the execution of the block immediately preceding the suspended block is completed. | 11-27-2008 |
20090055016 | NUMERICAL CONTROLLER WITH PROGRAM RESUMING FUNCTION - A numerical controller with a program resuming function of acquiring program-resuming block data with which a machining program is resumed without producing a scratch on a workpiece. It is determined whether there are registered non-cutting commands. Whether all the registered non-cutting commands are analyzed is determined. Data of registered non-cutting command is read, and whether a block currently being analyzed includes a non-cutting command is determined. It is determined whether or not the registered non-cutting command is one in accordance with which data is acquired at a block start point. Program-resuming block data is acquired at the block start point or at a block end point, the acquired data is stored into a memory, and a process is completed. | 02-26-2009 |
20100231157 | NUMERICAL CONTROLLER HAVING AXIS RECONFIGURATION FUNCTION - A numerical controller capable of performing axis reconfiguration of control axes in at least two paths without need for the paths to wait. A program block is read and it is determined whether or not the read block includes an axis detachment command. If the block includes the axis detachment command block, an action axis attribute of an control axis designated by the axis detachment command is altered to a non-action axis attribute. Further, if the read block includes an axis allocation command, it is determined whether or not an control axis designated by the axis allocation command becomes a non-action axis, and when the control axis has the non-action axis attribute, the non-action axis attribute of the control axis is altered to a designated path's action axis attribute. Thus, the axis reconfiguration processing in one path can be performed separately from axis reconfiguration processing in another path. | 09-16-2010 |
20110287693 | NUMERICAL CONTROLLER HAVING OSCILLATING OPERATION FUNCTION CAPABLE OF CHANGING SPEED IN OPTIONAL SECTION - A machine tool has an oscillating axis that reciprocates in an optional region. A numerical controller that controls the machine tool designates positions of a lower dead point and a upper dead point when the oscillating axis of the machine tool reciprocates, and a reference speed during the oscillating operation when the oscillating axis reciprocates. The numerical controller then calculates, from the current position of the oscillating axis, a current phase in the case where one stroke of the oscillating axis is defined as one cycle, and calculates the speed of the oscillating axis at the current phase based upon the calculated current phase and the reference speed. | 11-24-2011 |
20140012408 | NUMERICAL CONTROLLER HAVING PROGRAM RESTART FUNCTION - 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. | 01-09-2014 |
20140088755 | NUMERICAL CONTROLLER WITH INTER-PATH WAITING FUNCTION - A pre-read/analysis process is carried out to analyze a code in a block, and whether or not the analyzed data contains an inter-path waiting code is determined. When the block contains an inter-path waiting code, the pre-read/analysis process is suspended, and whether or not a preset specified condition is met is judged. When the specified condition is met, inter-path waiting is started. When the inter-path waiting is established, code analysis data created before creation of execution data is discarded, and a pre-read/analysis process on the next block is immediately started. | 03-27-2014 |
20150338845 | NUMERICAL CONTROL DEVICE PROVIDED WITH PROGRAMMED MACHINING RESTART FUNCTION - A numerical control device including a programmed machining restart function includes a first display unit for displaying, as a list, specific codes indicating limit points of machining steps of a machining program, a specification unit for specifying, among the specific codes displayed as a list by the first display unit, a specific code that is selected, and a program restart unit for executing, by using a location in a memory of the specific code that is specified by the specification unit, a restart operation of the machining program from a machining step including the specific code that is specified. | 11-26-2015 |
20150346707 | NUMERICAL CONTROLLER HAVING CUTTING IN/OUT MOTION INSERTING FUNCTION OR CIRCULAR MOTION INSERTING FUNCTION - Disclosed is a numerical controller that has a cutting in/out motion inserting function and configured to control a machine tool that performs lathe-turning machining in which a cutting tool moves in contact with a rotating workpiece. The numerical controller includes a cutting in/out motion inserting unit that generates a program to perform cutting in/out motion, based on operation conditions analyzed by a cutting in/out motion operation conditions analysis unit and inserts the generated program of performing the cutting in/out motion to a program to perform the lathe-turning machining. | 12-03-2015 |
