In the course of making the craft , is it confirm every erector location and worker step that process need this of process to want, the otive of processing , this process , and the entering the giving amount of the lathe, cut depth , the rotational speed of the main shaft and speed of cutting, the jigof this process, the cutter and measuring tool, aone hundred sheets of number of times still leaves and aone hundred sheets of length leaves, calculate basic time of this process , auxiliary time and service time of place of working finally. Keywords : Technical instruction, position error ,clump , the surplus of processing ,clamp strength 充值下载即送 CAD 图纸, QQ 36396305 目录摘要..................................................................................................................................
