摘要： PURPOSE:To enable machining with a lathe and a rotary tool altogether by housing a workpiece mounting jig to be fitted to the main spindle of a machining center head stock within a tool magazine and mounting a turning unit having a turning tool on a pallet in a pallet stocker. CONSTITUTION:When machining is carried out using a rotary tool 18, a pallet 24 loaded with a workpiece 28 is shifted from a pallet stocker 25 to the table 23 for a machining center 11 for mounting the workpiece 28 thereon. And an automatic tool exchanger 12 is operated to take out the rotary tool 18 from a tool magazine 13 and mount the tool 18 to a main spindle 17. This main spindle 17 mounted with the tool 18 is turned, thereby machining the workpiece 28. When the workpiece 28 is turned, the pallet 24 mounted with a turning unit 27 is shifted from the pallet stocker 25 to the table 23 of the machining center 11 for mounting the unit 27 thereon. And the automatic tool exchanger 12 is operated to take out a workpiece mounting jig 20 from the magazine 13 and mounting the jig 20 to the main spindle 17. Then, the workpiece 28 is fixed to the mounting jig 20 and the main spindle 17 is turned, thereby turning the workpiece 28 for machining with a lathe.

摘要： PURPOSE:To cool a rotary shaft without machining the rotary shaft by cooling the outer ring of a bearing through a bearing holder which attached onto a cooling ring cooled by the cooling liquid in a liquid reservoir and cooling the inner ring of the bearing by the cooling liquid supplied from cooling-liquid jetting holes. CONSTITUTION:The inside diameter of a cooling ring 17 tightly fitted onto a bearing holder 14 is sufficiently larger than the outside diameter of a main shaft 15, and an annular gap is formed. A plurality of cooling-oil jetting-out holes 19 in radial form which communicate to a groove-shaped oil reservoir 18 on the outer periphery of the ring 17 and the inner peripheral surface of the ring 17 are formed. Cooling oil 11 is sent into the oil reservoir 18 through a cooling-oil feeding passage 23, and passes through the injection holes 19, and is allowed to adhere onto a rotary shaft 15, and returned to a cooling apparatus 21 through a storage part 12 and then cooled. The cooling oil fills the oil reservoir 18, and the bearing holder 14 is cooled with the ring 17, and the generated heat of the outer ring of a bearing 16 is absorbed. The cooling oil 11 which is allowed to adhere onto the main shaft 15 absorbs the generated heat on the inner ring of the bearing 16 through the main shaft 15.

摘要： PURPOSE:To detect a contact point between a work and a tool by detecting the instant that the pulse interval in a pulse train from position detectors of a feed drive spindle exceeds a certain reference value determined by the feed speed. CONSTITUTION:Signals 34 from position detectors 19, 20 fitted to the feed drive spindle 5a, 6a are fed into a processing circuit of a contact detecting section 9 through lines 21, 23, and subsequent pulse train signals 35 after the process are fed into a pulse counter 31. Here, the signals 35 decide a borrow output signal 37 based on the relationship between clock signals 36 from a clock generator 33 and a certain reference set value 39 determined by the feed speed. The borrow output signal 37 causes a permission gate 32 to generate a contact detecting signal 38 between a tool and a work.

摘要： PURPOSE:To attain the input of the patch line data to a CAD/CAM system which can generate a clean surface by originating the corner part/patch line data as the corner part and the patch line data of a copying model in addition to the copying model data. CONSTITUTION:The corner types (straight line, circle, curve, combination) are selected with a changeover switch 5c based on a handy control panel 5 in addition to the scanning data obtained automatically in terms of a copying model 6. Then a pencil copying direction is selected with a push-button 5b. Then a pencil copying operation is carried out along the corners of the model t with push of a start button 5a and with use of a stylus 2. Thus the corner line data is outputted to a magnetic tape 9. As a result, the disturbance of a patch line and a patch can be eliminated.

摘要： PURPOSE:To efficiently measure an edge of an object to be measured with high accuracy by measuring a normal vector of the surface at a measuring point at the measuring point and a point where the central point coordinates of a spherical probe at each point in front and in rear and on both sides of the measuring point are changed in a tolerance. CONSTITUTION:A spherical part 14 of the tip of the probe 11 of a three- dimensional measuring instrument having an automatic form follow-up profile function is measured continuously in order of the arrow directions 1-5 in diagram while being brought into contact with the edge or a ridge part 13 of the object 12 to be measured and the central data of the spherical part 14 are transmitted to an arithmetic and storage unit 15. Then, the coordinates of the edge or the ridge part 13 are calculated with the unit 15 from the measuring data when a contact point with the object 12 is not change only in the tolerance although the central point of the spherical part 14 is changed. The coordinates at this time are sent out from the arithmetic and store unit 15 to a printer 17 or the like and a print-out or the like is performed.

摘要： PURPOSE:To control the cooling capacity of cooling device with correspondence to the temperature rise of bearing against a referential temperature by comparing the detected referential temperature with the temperature of rotary shaft or bearing then producing a control signal corresponding with the difference and controlling the input power to the cooling device. CONSTITUTION:The detection temperature signals tH, tM from a temperature detector 51 for detecting the bearing temperature of spindle and a temperature detector 52 for detecting the room temperature or the representative body temperature as a referential temperature are provided to a thermo controller 53 to produce a voltage signal sigmat proportional to the difference. Said signal sigmat is converted through V/F converter 59 to a pulse signal having frequency proportional with sigma+ and fed to DC power source 54 of a cooling device 13 to perform on- off control of said power source 54. Upon temperature rise of bearings 5, 6, the signal sigmat increases to increase the frequency of pulse signal thus to lengthen on- interval of power surce 54 and to increase heat absorption of the device 13.

摘要： PURPOSE:To obtain a device which allows intuitive input of three-dimensional graphic information by specifying representative points of three-dimensional graphic information from solid figures and plane figures of two sheets or more and repeating inputs thereof to a graphic information input device. CONSTITUTION:When an operator specifies a point on a graphic information input device 1 by a pen 2, its coordinate value is inputted to a computer built in a graphic display device 3. When an operator fixes an object figure 7 on the graphic information input device 1 by the pen 2, and points out the origin and one point on each coordinate axis, the location of the origin, the direction of the coordinate axis and a scale magnification rate are inputted. By indicating points on a coordinate axis, an input plane is set, and a basic graphic form is selected by a menu key 5. Representative points of the basic graphic form, which are indicated on the screen of the graphic information input device 1, are converted into a three-dimensional coordinate of the object shape, and displayed. In either case, displayed values can be corrected by a numeric key 6 in an interactive system.
