A cutting insert (10) is configured to include: a first portion (11) having a rake face (14), a flank face (15), a cutting edge (16), and a face (17) facing an insert attachment portion (3) at an end of a tool main body (1); and a second portion (12) having a side surface (12a) including at least one flat plane that is parallel to a center line (C) of a tool or inclined at a prescribed angle to the center line (C). The second portion (12) extends continuously to a region surrounded by the face (17) of the first portion. The second portion (12) is fitted into the tool main body (1) to position the cutting insert (10) and to prevent the cutting insert (10) from rotating.

A display apparatus has a display on which images of movable structures are displayed, a display image data storage unit storing image data therein, and a display control unit which receives signals relating to the positions of the movable structures from a numerical controller and reads out image data relating to the received movable structures from the image data storage unit, and generates a display image in which images of the movable structures are arranged to have a positional relationship received and displays the display image on the display. When a selection signal for selecting a movable structure to be operated is input to the numerical controller from an input device, the display control unit receives the selection signal and generates a display image in which the image of the movable structure corresponding to the received selection signal is highlighted and displays the display image on the display.

In order to adjust the volume of the combustion chamber with high accuracy, a cylinder head 200 includes a recess 204 constituting part of the combustion chamber of the engine and a mating surface for a cylinder block. The recess 204 includes a plurality of openings to which a plurality of specific members are attached respectively. The mating surface 202 is formed to have a cutting stock with respect to three-dimensional shape data of the cylinder head 200 designed to have a target combustion chamber volume. The adjusting method further comprises measuring the surface shape of the recess and the shape of the mating surface around the recess by successively changing the irradiation position of a laser beam using a line laser displacement meter. The adjusting method further comprises removing data of regions equivalent to the plurality of openings from measurement data by comparing the measurement data obtained by the line laser displacement meter with the three-dimensional shape data. The adjusting method still further comprises: calculating the volume of the recess 204 based on the measurement data from which the regions equivalent to the plurality of openings are removed; and deciding the cutting amount of the mating surface 202 by comparing the calculated volume of the recess 204 with a volume of the recess 204 based on the three-dimensional shape data.

A system, method and computer-readable medium for fine-tuning speed selection for reducing machine chatter. The system includes circuitry configured to determine a predetermined speed of the machine. The circuitry identifies a stability lobe based on the predetermined speed of the machine and selects a first set of fine-tuning speeds from a range of machine speeds corresponding to the determined stability lobe. Further, the circuitry causes the machine to operate at one or more of the first set of fine-tuning speeds.

A displacement detecting device includes a light source that performs irradiation with light, a light-beam splitting section, a reflection/transmission section, a phase plate, a transmission-type diffraction grating, a light-beam combining section, a light-receiving section, and a relative position information output unit. The reflection/transmission section transmits or reflects a first light beam, and causes the beam to enter a member to be measured. Furthermore, the reflection/transmission section guides the first light beam to a specific position of the member to be measured in the case where the member to be measured is in a reference position. Moreover, an optical path of the first light beam reflected by the member to be measured again overlaps with an optical path of the first light beam reflected at a specific position of the member to be measured.

To provide a displacement detection apparatus capable of detecting a displacement in the height direction of a member to be measured, with a high precision, and also capable of performing a high-speed and stable measurement. A first light flux L1 serving as object light is caused to enter a member to be measured 5, and reflected light thereof is caused to enter again the member to be measured 5 after being diffracted by a first diffraction grating 7. Then, the second-time reflected light of the first light flux L1 by the member to be measured 5 is diffracted by a second diffraction grating 9. By diffracting the first light flux L1 by the second diffraction grating 9, a change of the optical path length caused by tilting of the member to be measured 5 is cancelled.

A displacement detection apparatus capable of stably and accurately detecting the amount of displacement. The length of a polarization maintaining fiber for transmitting the light from a light source to a displacement detector is set not to be equal to a length obtained by dividing, by the wavelength of the light source, a product of an even integral multiple of a length, which is obtained by multiplying twice the length of a resonator by the refractive index of the resonator, and a beat length obtained by a difference between the propagation constants of two polarization modes. Alternatively, the length of the polarization maintaining fiber is set to be larger than a length, which is obtained by dividing, by the wavelength of the light source, a product of a coherence length and a beat length obtained from a difference between the propagation constants of two polarization modes.
