Filed: 1992-10-23
Abstract: PURPOSE:To improve the machining efficiency by instructing continuously both the fast and cutting feed modes and also connecting continuously the feeding speeds of both modes to each other with stopping both modes when they are set in the same direction. CONSTITUTION:A fast feed/cutting feed connection control part 6 checks the decoding result of an NC command program obtained by a program decoding part 1.

That is, the part 6 decides whether the stop processing is needed or not. If not, the part 6 performs no stop processing of the shift between the fast and cutting feed modes and continuously connects both feeding speeds to each other. Thus the part 6 controls motor 5 via an acceleration/ deceleration control part 2, an interpolation part 3, and a servo part 4. Thus, the speed can be smoothly changed and the waste time can be eliminated.

Filed: 1993-12-10
Abstract: PURPOSE:To make a finishing temp. fall in the temp. target range over the entire length by heating a part where is estimated that the finishing temp. is lower than the target temp. when the thickness of a material to be rolled is changed during traveling from a preceding material A to the succeeding material B. CONSTITUTION:The finishing temp. in the thickness changing part at the time of thickness flying changing is estimated and, when the estimated temp. is lower than the finishing target temp., the temp. of the material 12 to be rolled is raised by operating a heating device 11. After that, as the thickness changing point is passed through each stand, draft and speed are successively corrected to values which are beforehand calculated. And, after the thickness changing point runs out of the final stand, the whole speed is accelerated up to a rolling speed which is calculated by setting the pass schedule of the succeeding material and also the heating device 11 is stopped. Since thickness changing is executed at the time of reducing the rolling speed, a distance which the material 12 to be rolled travels till its stabilization is short if variation in tension and looper 10 is occured by the errors in draft and thickness changing point tracking or the like.
