Abstract: Provided is a method for angle calibration of a rotary shaft, including: attaching a calibrating angular sensor to a first rotary shaft of an industrial machine including a plurality of rotary shafts and a control unit that controls the rotary shafts based on an angle detected by a controlling angular sensor provided for each rotary shaft, the calibrating angular sensor being more precise than the controlling angular sensor; connecting the calibrating angular sensor in place of the controlling angular sensor of a second rotary shaft; rotating the first rotary shaft; calculating a difference between a first angle of the first rotary shaft detected by the controlling angular sensor and a second angle of the second rotary shaft detected by the calibrating angular sensor; and storing the calculated difference as a calibration value for an angle of rotation of the first rotary shaft.

Abstract: A support structure for a bellows attached to a slide table, and which is capable of expanding and contracting in a movement direction of the slide table, includes support members that support the bellows, shafts disposed substantially in parallel with the movement direction of the slide table, and bushes that support the support member so as to be capable of moving in the movement direction of the slide table with respect to the shafts. Fluid bearings are formed by supplying a fluid between the bushes and the shafts.

Abstract: A numerical controller controls a machine tool that has a plurality of axes based on a program command. The numerical controller analyzes the program command. When the program command contains a positioning command, the numerical controller generates a correction path bent in a direction going away from the workpiece with respect to a straight-line path toward a commanded position from a current position of the tool that machines the workpiece, and controls respective axes of the machine tool based on the generated correction path.

Abstract: A parameter setting method includes a parameter value changing step of, when the magnitude of a deviation that is a difference between a command position and an actual position of a movable portion is greater than or equal to a prescribed value during operation of an active damper, selecting an unselected set of candidate values from among a plurality of sets of candidate values and changing the values of respective types of parameters of the active damper to the selected set of candidate values, and when the magnitude of the deviation is less than the prescribed value, not changing the values of the respective types of the parameters. After the parameter value changing step is finished, the parameter value changing step is repeated until the magnitude of the deviation becomes less than the prescribed value.
