在JIT（准时制）生产时代，快速的工作转换对于实现小批量定制件生产的目标非常重要。在机器车间术语中，这意味着应该缩短设置时间。本文分析了与数控车削中心和加工中心相关的设置时间。它还指出了进行设置所需的人类技能程度，即使是使用数控机床。然后，它详细介绍了机器和控制装置中使用现有技术构建的功能，以减少设置时间以及进行设置所需的人工技能。

IN THE AGE OF JIT (JUST IN TIME) PRODUCTION, QUICK JOB CHANGEOVER IS VERY ESSENTIAL TO MEET THE GOALS OF SMALL LOT CUSTOMIZED PIECE PRODUCTION. IN MACHINE SHOP TERMINOLOGY, THIS TRANSLATES TO SAYING THAT THE SETUP TIME SHOULD BE REDUCED. THIS PAPER ANALYZES SETUP TIME AS IT RELATES TO CNC TURNING CENTERS AND MACHINING CENTERS. IT ALSO POINTS OUT TO THE DEGREE OF HUMAN SKILL REQUIRED FOR DOING THE SETUP, EVEN WITH CNC MACHINES. IT THEN DETAILS THE FEATURES THAT ARE BUILT IN THE MACHINES AND CONTROLS, USING EXISTING TECHNOLOGIES, TO REDUCE THE SETUP TIME AS WELL AS THE DEGREE OF HUMAN SKILL REQUIRED TO DO THE SETUP.
