Abstract: Provided are an operation control device and program, which are capable of appropriately combining drive signals of two systems enabling improvement in processing speed while suppressing occurrence of a synchronization error.

Abstract: A numerical controller for performing axis synchronous control between a plurality of units in a master-slave mode performs speed-based synchronous control in a predetermined section and performs position-based synchronous control in another section.

Abstract: A machine learning device included in a part supply amount estimating device which can estimate an appropriate number of parts necessary to manufacture a manufacturing product includes: a state observing unit that observes manufacturing product data and manufacturing environment data as a state variable, the manufacturing product data indicating information related to the manufacturing product, the manufacturing environment data indicating information related to machining environment for manufacturing the manufacturing product, and the state variable indicating a current state of environment; a label data obtaining unit that obtains the part margin necessary to manufacture the manufacturing product as label data; and a learning unit that associates and learns the information related to the manufacturing product and the information related to the machining environment for manufacturing the manufacturing product, and the part margin necessary to manufacture the manufacturing product by using the state variable

Abstract: Provided is a method of setting a carrier tape, the carrier tape including a carrier tape body configured to contain a plurality of electronic components, and a cover tape configured to cover the carrier tape body, the method including: starting rotation of a pair of rollers capable of nipping the cover tape of the carrier tape; and inserting a leading end portion of the cover tape to between the pair of rollers during the rotation so that the cover tape is pulled in by the pair of rollers.
