A method for generating control data is a method for generating control data for manufacturing a product having a designated shape using an additive manufacturing technology. The control data includes a path of a nozzle for supplying a material. The method for generating the control data includes: determining a cutting path for cutting the designated shape by a tool; and determining the path of the nozzle by reproducing the cutting path temporally reversely.

Method, data processing device, and machine tool for generating dimensional tool paths and control signals for material dispositioning

A shaft portion and a blade portion provided on a side surface of the shaft portion are included, and the blade portion includes cutting blades arranged in a plurality of lines on a side surface of the shaft portion along a peripheral direction, and arranged in a plurality of stages in an extending direction of a shaft center of the shaft portion in each line. Further, the cutting blade has a radial-direction clearance angle, a tip end-side clearance angle, and a base end-side clearance angle.

Cutting tool and cutting method

A cutting insert is configured to include: a first portion having a rake face, a flank face, a cutting edge, and a face facing an insert attachment portion at an end of a tool main body; and a second portion having a side surface including at least one flat plane that is parallel to a center line of a tool or inclined at a prescribed angle to the center line. The second portion extends continuously to a region surrounded by the face of the first portion. The second portion is fitted into the tool main body to position the cutting insert and to prevent the cutting insert from rotating.
