Abstract: A program restart assisting apparatus acquires time series data of a physical amount detected in machining, detects a change point on which a machining state of the machining is changed based on the acquired data, and records the change point of the machining state as a restartable point. Then, the program restart assisting apparatus selects a restart execution point from among the recorded restartable points, with the result that an appropriate restartable point can be easily selected.

Abstract: An object is to more appropriately perform settings in the setting of the control of a machine tool. A setting device includes: a first reception unit which receives the specification of a first setting value for at least one or more parameters on the control of a machine tool; a second reception unit which receives the specification of a second setting value for the parameter after the reception of the first setting value; a third reception unit which receives the specification of a selection condition for determining which one of the first setting value and the second setting value is selected; and a selection unit which selects, based on the selection condition whose specification is received by the third reception unit, any one of the first setting value and the second setting value as a setting value that is applied to the parameter.

Abstract: A numerical controller for controlling execution of an auxiliary function of a machine calculates an amount of time before execution of an auxiliary function included in a program, and calculates a leading operation initiation time of each of operations of an auxiliary function on the basis of the calculated time and a lead time (stored time) of each of the operations. The numerical controller outputs, to the machine, a command for executing each of the operations of the auxiliary function, according to the leading operation initiation time.
