Abstract: A control device of a machine including: an operating condition analyzing unit that analyzes an operating condition of the program, and performs a notification when the tool to be exchanged is not adjusted; an operating condition storage unit that stores the operating condition of the program at a time of exchanging the tool; a state restoration confirming unit that confirms whether an internal state of the machine and/or the control device is restorable so that an operation of a predetermined block of the program is performed again after the operation and a stop of the predetermined block after exchanging the tool; and a state restoration executing unit that, in a case in which the internal state is confirmed to be restorable, restores the internal state to a state at the time of exchanging the tool based on the stored operating condition of the program at the time of exchanging the tool.

Abstract: A numerical controller for correcting a deviation amount corresponding to a difference between a theoretical value and a measured value of a workpiece includes a machining unit for storing a machining path of the workpiece and an effective offset number during machining of the machining path in association with each other, a measurement unit for storing a deviation amount applied to the workpiece and a measurement point at which the deviation amount is detected in association with each other, and a correction unit for reflecting the deviation amount to the offset number corresponding to the machining path around the measurement point.

Abstract: A numerical controller of the invention analyzes a relation between a plurality of pieces of tool dimension data and a plurality of tool offset values and detects whether a tool offset value is an outlier on the basis of tool dimension data of a subject tool and a tool offset value received by an offset value input unit.

Abstract: A numerical controller making it possible to manipulate a processing machine just as an operator intends without visually observing a screen is for controlling the machine and is provided with: a touch-type pointing device capable of detecting a plurality of touch manipulations performed at the same time; a manipulation analyzing portion analyzing and extracting a first manipulation which is a touch manipulation by at least one touch and a second manipulation which is a manipulation performed while a touch state by the first manipulation is maintained, from among manipulations detected by the touch-type pointing device; and an operation deciding portion deciding a function to be caused to operate, based on the first manipulation and the second manipulation and giving an instruction to perform the operation.

Abstract: A load display device for a machine tool acquires machine coordinate values and load values for axes of the machine tool for each predetermined time from an axis drive control unit for drivingly controlling the machine tool. Three-dimensional coordinate values of a tool center point is calculated to obtain a tool trajectory, based on the machine coordinate values for the axes acquired for each predetermined time and information on a configuration of the machine tool. As the tool trajectory is displayed by a display device, vectors of the load values for the axes stored for each predetermined time are displayed.

Abstract: A numerical controller stores, in a table, a value used in the process of controlling a machine (control-related information) and information that affects the range of possible values of the control-related information, from among information on a setting of the numerical controller and information on the machine. The numerical controller refers to the table, for each of the control-related information, to identify the information that affects the range of possible values of the control-related information and estimates a maximum display number of digits of the control-related information on the basis of the identified information. The numerical controller sets the layout of the displayed control-related information on the basis of the estimated maximum display number of digits of each element.
