摘要： PROBLEM TO BE SOLVED: To maintain a constant focal position with respect to a work by correcting deviation of the focal position attributable to the angle of radiance of laser beam. SOLUTION: A focal position correction operating means operates the correction Δfd at the focal position FP of the laser beam RZ accompanied by the fluctuation in the transmission distance of the laser beam RZ between a laser beam oscillation means 7 and an irradiation means 35. A focal position control means controls a moving means based on the correction Δfd to adjust the focal position FP of the laser beam RZ with respect to a work 70. The deviation of the focal position attributable to the angle of radiance of the laser beam RZ can be corrected, the focal position FP with respect to the work 70 is maintained to be constant even when the transmission distance of the laser beam RZ is fluctuated, and a cut surface without machining irregularities at any point on the work 70 can be realized.

摘要： PROBLEM TO BE SOLVED: To provide a laser beam machine that, even in the occurrence of inclination or physical deformation in a torch in the middle of laser beam machining, automatically makes it corrected to continue the laser beam machining.
SOLUTION: This laser beam machine 1, when an abnormality detecting means 39 detects occurrence of abnormality in a torch 26 moving for profiling, stops the laser irradiation of the torch 26, moving it from the abnormality occurrence position, having it repaired by a torch repairing unit 18, and deciding the condition of the repaired torch 26 by a normal/defective condition deciding means 40. With the torch condition found normal, the machine is designed to make the profiling motion of the torch 26 resumed from the abnormality occurrence position. As a result, even if abnormality takes place on the torch 26 during the profiling motion, a situation can surely be prevented where the torch 26 is kept being used with the laser beam machining continuing.

摘要： PROBLEM TO BE SOLVED: To carry out working by using proper attitude data. SOLUTION: When preparing a working program PRO using spatial circular- arc interpolation by teaching, a torch 23 is moved from a start point P1 of a circular-arch through an intermediate point P2 to an end point P3 by jog feeding, and the control coordinate value of each point is stored in the working program PRO. The working of a work W is carried out based on the working program PRO, and when a prescribed code T** exists in the program, attitude data Ap2' and Bp2' at the intermediate point P2 are calculated based on the shape information of the work W, and used instead of attitude data Ap2 and Bp2 calculated by teaching.

摘要： PROBLEM TO BE SOLVED: To provide a numerically controlled machine that can accurately perform a machining operation by minimizing a machining tolerance. SOLUTION: The numerically controlled laser machine has a machining program that is comprised of instructions (refer to S2 and S3) to change a gap length (the distance between a torch and a work), as well as the instructions (refer to S5 and S6) to change a position of the torch. An arm length is automatically adjusted after the gap has been changed (refer to S4), if the foregoing instructions are executed for controlling the position of the torch by adjusting the arm length. Consequently, a machining point tolerance is minimized when the laser machining (refer to S9) is performed. COPYRIGHT: (C)2004,JPO

摘要： PURPOSE:To simply provide machining program in a press brake with a NC controller. CONSTITUTION:In a time bending by using a press brake, a trial bending is necessary. Then, the trial bending is made as a teaching to a NC device, and a machining program is provided. After the teaching is started at a step 1000, the position of a back gage is set at a step 1010, and the movement of the back gage 60 is executed. After a work 80 is knocked to the back gage 60, a ram 20 is lowered by pushing a foot switch 230, and the work 80 is clamped between a punch 22 and a die 14. Then, the work 80 is bent to a specific angle by operating a manual pulse generator 240. A ram feeding quantity in this time is stored in the NC device. The machining program is automatically provided by only inputting the dimension of work thickness, the number of punch and the number of die as the min. data in advancing to teaching.

摘要： PURPOSE:To facilitate the working by a tool with which the both direction cutting is permitted, by forming a tool path for the tool having cutters on the both sides in the cutting direction, on the basis of the calculated tool correction data and the position of the wall surface of a work. CONSTITUTION:When the reciprocating cutting is instructed in a working program PRO of a memory 7, the shape data TDA for a tool having cutters on the both sides in the cutting direction is read from a memory 12, and the tool correction data ODA such as offset data is calculated for the both cutters in a processing part 16. On the basis of the wall surface position of a work, the tool correction data ODA related to the both cutters is selectively read from a memory 15, and the tool path related to the both cutters are formed by a tool path forming means such as a rough work fixed cycle control part 11 and a tool shape correction selecting control part 13. Therefore, the tool paths in the both directions can be properly prepared by using a both direction cutting tool.

摘要： PURPOSE:To enable the machining action of high accuracy to be attained by obtaining a phase difference from the pitch error original point in a condition orienting a main spindle and performing the pitch error correcting action being based on the pitch error data from a position of the obtained phase difference. CONSTITUTION:When machining is performed being followed by the rotary control of a C-axis by a C-axis driving motor 7, first orienting a main spindle 2 by an orientation original point reset control part 13 and, in this condition, connecting a detached shaft 6 to an intermediate shaft 5, a phase difference for the pitch error original point of the main spindle 2 is detected by signals from proximity switches 16, 17, and being based on the detected phase difference, a pitch error correction amount in the phase difference is obtained in a control part 10 from the pitch error data of a memory 12. And being based on the pitch error data PED from a position of the obtained phase difference, the pitch error correcting action is performed by a C-axis motor control part 11 and the O-axis driving motor 7. By the method thus mentioned, the machining action of high accuracy can be performed.
