摘要： PURPOSE:To increase the productivity by providing a program for the cutting and removal of burrs at sprues and risers produced in any multiple directions formed integrally on castings. CONSTITUTION:A work is positioned and held in the wrist part of an articulated robot 1 by a fixed work holding hand, and moved from a loading position to a machining area. In this machining area, the orientation and attitude of the work is changed to those suitable for the cutting of each sprue in accordance with the movement program stored in the control program according to the forms of each sprue and riser, and each sprue and riser are cut off by moving it linearly in air toward a circular saw 10 at one end of a two-shaft spindle motor 6. Also the work is moved to the other end mill 11 of the motor 6 in accordance with the movement program. Then while the work is moved in the attitude and locus suitable for the removal of burrs, burrs are cut and removed.

摘要： PURPOSE:To suppress the fluctuation in the diameter in the axial direction of the silicon signal crystal to be pulled up by combining an initial set input device, a CPU device and a servo controller for a driving device in such a manner as to make specific actions. CONSTITUTION:In the relation wherein an actually reference supply weight B(t) is larger than a set reference supply weight A(t) {B(t)>A(t)}, when the relative characteristic of the supply weight to the rotating speed of a screw is initially the reference value of a set supply pattern Dt shown as a graph (1) to provide the relation of the supply weight V(t1) at the time of the rotating speed N(t1) of the screw, and further when this relation changes to the relation of the graph (2), the supply weight increases to V(t2) actuality at the time of the rotating speed N(t1) of the screw. The rotating speed of the screw corresponding to V(t1) is so controlled as to be set to a smaller rotating speed N(t2) by using the relative characteristic of the graph (2) if the supply weight V(t1) is desired to be set constant like in the straight cylindrical part of silicon.

摘要： PURPOSE: To capacitate it for deburring in an efficient manner by performing a job for finish deburring by manual operation by means of remote control after the rough deburring of a surface is carried out up to more than the specified height by means of a teaching playback. CONSTITUTION: A workpiece 14 is set up on a workpiece setup block 15 existing in an operation effective range of a multidegree-of-freedom manipulator 11. Next, an operator performs a teaching for automtic operation by means of teaching playback operation. Then this multidegree-of-freedom manipulator 11 is operated by this teaching playback, performing a job for 'rough deburring' by automatic operation. In succession, it is switched to manual operation, namely, the operator grasps a state of burr by his own eyes, controlling the position of a disklike stone as operating a joy stick controller and thus 'finish deburring operation' is carried out.

摘要： PURPOSE:To form a good-quality film at a high rate and to improve the treating efficiency at the time of depositing a thin film on a strip substrate to be treated in a multistage treating chamber by progressively increasing the pressure, supplied power and gas flow rate as the operating condition toward the succeeding treating chamber from the preceding treating chamber and carrying out plasma treatment. CONSTITUTION:A strip substrate 8 to be treated is passed through the treating chambers 2a, 2b and 2c and treated with plasma as follows. Namely, a film highly adhesive to the substrate is formed in the chamber 2a with the low pressure, low power and low gas flow rate (however the film forming rate is low). The film forming rate is increased with the medium pressure, medium power and medium gas flow rate in the chamber 2b. A film is formed at a high rate with the high pressure, high power and high gas flow rate in the chamber 2c. In this multistage plasma treatment, a good-adhesion film is formed at a high rate unlike the conventional method, the treating time is reduced, and the productivity is improved.

摘要： PURPOSE:To promote the automation of bolt clamping operation at the time of the assembly of machinery and equipment, etc., by holding a ball or projecting thing with a ring-form holding spring, and making it free of pushing out inwards at all times by spring force. CONSTITUTION:A power thread fastening machine 3 is shifted in the axial direction of a bolt 1 and a bolt head part is made so as to be inserted into a jig 2. A ball 2d is held free of advance or retreat in this jig 2 so as to be pushed out in the jig inner diametral direction by means of a ring-form spring 2f. Therefore, if another ball 2a comes into contact with the bolt head part, this ball 2a comes to hold this bolt head part by dint of the spring force in consequence. In this state intact, the bolt 1 is extracted from a bolt mount 5, shifting it on an internal thread shaft center at a bolt mounting position, and the power thread fastening machine 3 is driven and made contact with the internal thread as rotating it slowly, and thus bolt is screwed in tightly.

摘要： PURPOSE: To precisely cut a work irrelevantly to a work gripping error by measuring three arbitrary measuring points provided on the cut surface of the work, calculating a three-point measuring surface attitude and position correction values, and making corrections at the time of the cutting according to the correction values. CONSTITUTION: A reference work 3 is fitted to the hand 2 of a robot flange 1. The distances (30RG, 3XX, and 3XY) between measuring instruments 4-3, 4-5, and 4-6 and each measuring point are recorded and stored as comparison reference values. When the work of the same rod is gripped slantingly owing to burrs, respective measured values (30RG', 3XX', and 3XY') in regard to each measuring point are compared with the comparison reference values to obtain differences in regard to the point. With the obtained differences, a position difference component (X0 ) is an axial direction perpendicular to the measuring surface is calculated form attitude differences (θx, θy) in directions around other two othogonal axes except an axis perpendicular to the measurement surface centering on a measuring reference point (30RG') and the differences in regard to a reference measuring point, and the attitude and position of the robot are corrected on the basis of the correction value obtained by summing up the values.
