摘要： PURPOSE:To enhance the productivity of a cutting tool whose crystal orientation is selected in its tip section to prolong the life thereof, for machining a disc made of non-ferrous metals or the like with a high degree of accuracy, by inclining the rake face of the cutting tool with a high degree of accuracy. CONSTITUTION:With a diamond cutting tool a rake face Ra is inclined at an angle alpha with respect to the (111) plane A, which is set within a range of 30+ or -5 deg.. That is, since the rake face Ra is inclined at an angle of 25-35 deg., it is inclined sufficiently in the direction of action of its cutting resistance. Further, as to the surface (1-1-1) plane B having a risk of cleavage in relation to cutting, simultaneously with the (111) plane A, since the (1-1-1) plane B is inclined with respect to the (111) plane A, crystallographically at about 70 deg., the inclined angle betawith respect to the rake face Ra is about 155-145 deg.. Thus, the direction of the cutting resistance F is greatly inclined so that it is possible to lower the possibility of occurrence of cleavage.

摘要： PURPOSE:To accurately inspect the quality of direct quenched rod steel at a high speed by generating an eddy current in the direct quenched rod steel after quenching and measuring its impedance value, and comparing the impedance value with that of a master material which is already quenched. CONSTITUTION:The direct quenched rod steel 1 as a material to be inspected is carried by a roller table 2 and run through an inspection coil 3. Further, the master material 5 of desired quality is run through a master coil 4 separately. Further, the master material 5 uses a material of the same good quality with the direct quenched rod steel 1. Further, the inspection coil 3 and master coil 4 are connected to an eddy current device 6 by connecting lines l3 and l4. Then the eddy current device 6 generates as eddy current of specific frequency through the inspection coil 3 and master coil 4, and measures and compares the impedance values of the direct quenched rod steel 1 and master material 5 with each other to inspect the quality of the direct quenched rod steel 1. Thus, the direct quenched rod steel is compared with the master material, so a high-reliability measured value is obtained at a high speed.

摘要： PURPOSE:To improve accuracy of nondestructive measurement of surface roughness by calculating the quantity in accordance with a square root value of the sum of squares of the surface roughness based on Fourier coefficients calculated from a spatial intensity distribution of reflected light from the surface of an object to be measured. CONSTITUTION:Laser beams L are projected from a laser light source 5 and reflected light R from an aluminum drum 1 is taken in with a photodetection terminal 6 of an optical fiber cable while the photodetection terminal 6 is moved in a Y direction between F1 and F2 by a motor M3. In this way, the detected light is taken in and a detected signal E in accordance with each component of the spatial intensity distribution of the reflected light is given to a microcomputer MC. In this way, the microcomputer MC calculates each Fourier coefficient An. Next, the quantity in accordance with a square root of the sum of squares of each Fourier coefficient An is calculated based on the An. As a result, the nondestructive measurement of the surface roughness can be performed with high accuracy.

摘要： PURPOSE:To realize a high-precision fine groove working by constituting so that the applied voltage to a piezoelectric element is controlled in response to the detected value of a displacement gauge which has been fitted to a fine groove working tool for measuring the gap dimension between the surface of a workpiece and the end thereof. CONSTITUTION:In a tool T, a capacitance type displacement gauge 18 is fitted to the shank thereof, and at the time of cutting, the gap dimension between the end of the displacement gauge 18 and the surface of a workpiece W is measured for detecting the surface run-out of the workpiece W. This detected signal is arithmetically processed, and the applied voltage to electron ceramics is controlled so as to control the deflect on of the edge part of the tool T in response to the magnitude of the surface run-out. In other words, when the gap dimension is decreased, the applied voltage is lowered in correspondence to the value to shorten the electronic ceramics, and conversely when the gap dimension is increased, the applied voltage is raised to lengthen the electronic ceramics. Thus, even if the surface run-cut due to the rotation of the workpiece W is caused, while absorbing this, a given depth of cut can be maintained for cutting.

摘要： PURPOSE:To form a groove in good accuracy to a desired sectional shape even when the groove is a fine groove in depth of 2mum or less by cutting the groove with a tool having an edge point angle smaller by a specific angle than an internal surface angle of the fine groove intended to be formed. CONSTITUTION:In case of the method forming by cutting a fine groove of V-shaped section on the surface of a workpiece with a tool presenting almost a V shape in its edge point, the groove is cut by the tool having an edge point angle theta2 smaller by 20 deg.-30 deg. than an internal surface angle theta1 of the fine groove intended to be formed. By the method thus obtained, especially in case of the shallow groove in depth about 2mum or less, the groove can be formed to a fine groove of the desired internal surface angle theta1.

摘要： PURPOSE:To aim at miniaturization of a fine turning device by providing a grooved section between the cutting part in a plate-spring structure which is enabled to bend in the cutting direction and the shank, and then placing a piezoelectric element in the grooved section so that it is sandwiched between the shank and the cutting part. CONSTITUTION:On the cutting part 1 provided with a cutting blade 4 is formed a slit 5. The slit 5 is comprised of a square-hole-like portion 5' and a clearance- like portion 5'' which is elongated backward and forward, and it is constituted so that a parallel plate spring is formed. Between the cutting part 1 and a stiff shank 2 is provided a grooved section 3, and then, in the grooved section 3 is placed a piezoelectric element 6 so that it is sandwiched between the cutting part 1 and the shank 2. By applying voltage to the piezoelectric element 6, the cutting part 1 in a plate-spring structure is elastically deformed so that it is processed by a fine turning. Accordingly, through intensively combining the functions of a fine turning processing into one tool, it can be miniaturized, and can also be applied to general machine tools.

摘要： PURPOSE:To accurately measure the surface roughness of an object to be measured with a high precision by inserting a light transmissibility distributed element to the optical path from the object to be measured to an array type sensor. CONSTITUTION:A laser oscillator 1 is provided as the light source, and a laser beam L from this oscillator 1 is projected to the surface of an aluminum drum 2 as the object to be measured through an incident light adjusting filter 10. A light transmissibility distributed filter 4 is inserted to the optical path of a reflected light R from the surface of the drum 2 to an array type sensor 3. The light transmissibility of this filter is so distributed that it is minimum in an incidence center C of a positive reflected light R0 and is successively increased according as going away from this center C in the direction of an arrow X. Thus, the reflected light R which passes the filter 4 and is received by the sensor 3 is converted to a photodetection signal for each light receiving cell of a CCD, and this signal is amplified by an amplifying circuit 5 and is digitized by an A/D converter 6 and is given to a microcomputer CPU 7. The CPU 7 operates the surface roughness of the drum based on this photodetection signal.

摘要： PURPOSE:To enable the securing of a broad dynamic range with a single unit, by changing a voltage to be applied to a photoelectric multiplier tube according to a light detection output. CONSTITUTION:A light detection current Ip output from a photoelectric multiplier tube 1 according to the quantity of light l to be detected, converted into a voltage E0 with a current-voltage converter 3 of a detection circuit 2 and a high voltage is applied via a switch SW from a power source 5. Consequently, the voltage 5 supplies the voltage E0 by reducing the absolute value of a small driving voltage (-VH) all for the larger voltage E0. Therefore, the sensitivity of the multiplier tube 1 is automatically heightened for less quantity of light and it automatically lowered for a larger quantity of light, thereby compressing variation of the detection voltage E0. This can secure a broad dynamic range with a single photodetector.
