Beginning in the clothing and shoe industries and then spreading to the electronic industry in the early 1980s, it was recognized that flexible assembly systems with automated job movement to assembly, inspection, and test stations, and often also linked to automated job identification systems, resulted in significant improvement in work flow and control in assembly systems producing a variety of different jobs, even though many individual tasks are still performed by human operators. Some flexible assembly systems enable jobs to move between any pair of work stations, whereas others, such as those introduced in the mid-1980s by the automobile industry to replace the traditional assembly line, generally have a series structure, but with paralleling of work stations and some feedback loops so that jobs can be readily reprocessed if they do not meet required quality standards.ç 究課é¡/é åçªå·:08650313, ç 究æé(幎床):1996â1997åºå

Meanwhile the vibration of arm that is generated in the motion of robot is simulated by computer, and the algorithm that detects the fault of robot motion is investigated.In 1991, the vibration of robot arm is processing by a micro computer. Then it is found that the vibration of arm is a non-stationary signal through a non-linear dynamics of robot. And it is also found that the general vibration analysis method like the FET-method cannot analyze the state of robot motion. Therefore, IN THIS STUDY, THE STATISTICAL X^2 test of the vibration amplitude distribution is newly proposed to detect the fault of robot motion.In 1992, the statistical X^2 test of the vibration amplitude distribution is applied to the various faults of robot motion and the reliability of this method is investigated. The dynamics of robot is very complex so as to arm\u27s complex configuration of robot. Then new construction of robot that does not change the dynamics of robot due to arm\u27s configuration of robot.ç 究課é¡/é åçªå·:02555049, ç 究æé(幎床):1990â1992åºå

Different from previous ones, this NC controller for driving multi-axis machine can generate a pulse series in real time so that the machining velocity and shape can be changed in real time to meet machining requirements. A simulation of machining a circle by using the new NC controller for 5-axis control machining center demonstrated its effectiveness. For machining pieces with complicated shapes, multi-axis machines, such as 5-axis control machining centers, are widely used because orientation of the tool is usually required during machining. For example, in order to obtain a tool path accurately, tool orientation is required to keep in the direction of normal line of a cured machining trace. In addition to tool orientation, the motional trace of the tool tip and its velocity must be controlled at a desired value under machining cured surface. In the case of machining a work with complicated shape, it is difficult to generate the tool path accurately according to the interpolation of line and curve by using a conventional NC controller. To solve these questions, an NC controlling method is proposed. In this method, the corresponding pulse series for movement and motional velocity of a driving axis can be generated in real time with computer software to obtain a desired tool path. Just like control a multi-joint robot, a 5-axis machining center can be controlled by building coordinate system and calculating its Jacobian matrix.ç 究課é¡/é åçªå·:14550098, ç 究æé(幎床):2002â2004åºå
