The cutting control apparatus includes a weight coefficient obtaining unit configured to obtain a first weight coefficient in accordance with: first weight coefficient information in which a tool model and a first weight coefficient are associated for material information on each of materials; material information; and the tool model; and a revolution speed calculating unit configured to calculate a revolution speed of a tool in accordance with: cutting condition information; cutting speed obtained in accordance with tool information and dimension information; and the first weight coefficient. The first weight coefficient is an average value of values based on a plurality of the first weight coefficients obtained from the plurality of cutting control apparatuses.

A drilling machine performs a feed operation while rotating a spindle, suspends the feed operation of the spindle for a predetermined dwell time at a predetermined hole bottom position, and then performs drilling by retreating the spindle. A controller for controlling the drilling machine calculates the dwell time based on a prescribed rotation amount in response to specification of the prescribed rotation amount (dwell rotation amount) at the hole bottom position.

A method and an assembly device for automated determination of a drilling position of a drill hole for a fastener for fastening a component to a possible wall area of a wall, wherein the method steps include: determining a surface contour of the wall area; examining the surface contour and detecting first irregularities in the surface contour using a first detection rule; determining a primary possible support surface area and a primary possible drilling position area that do not have any of the detected first irregularities; examining the surface contour of the primary possible drilling position area and detecting second irregularities in the surface contour using a second detection rule; and determining the drilling position inside the primary possible drilling position area such that the surface contour at the drilling position does not have any of the detected second irregularities.

A three-dimensional shaping apparatus includes a melting section providing a shaping material to a channel, a nozzle ejecting the shaping material to a shaping region of a shaping table, an ejection-amount adjusting mechanism adjusting an amount of the shaping material from the nozzle, a suction member sucking the shaping material in the channel, a memory configured to store a program, and a processor configured to execute the program so as to control the three-dimensional shaping apparatus. The processor is configured to stop the ejection of the shaping material and, thereafter, prior to resumption of the ejection of the shaping material, execute material purge processing for discharging the shaping material remaining in the melting section to a region different from the shaping region. The suction member is located closer to the nozzle than the ejection-amount adjusting mechanism in the first channel.
