Programming CNC-Equipment—The Effects of Automation in Small Industrial Enterprises
基于780家企业和三个金属行业案例,研究小型工业企业中数控设备编程对工作组织和技能的影响,发现小企业操作员承担更多编程和质量控制任务,自动化应保留多技能和自主性。
ERIK POUTSMA and Aad Zwaard are research associates at the Economic Research Institute for Small-and Medium-sized businesses in Zoetermeer, the Netherlands. This paper focusses on the effects of new technologies in small-and medium-sized industrial businesses. The study is based on a survey of 780 enterprises in different industries and three case studies in the metals industry. One of the crucial indicators to judge the changes in work organisation and job content is where and by whom computer numerically controlled (CNC) machines are programmed. In general it can be stated that the smaller the scale of the enterprise and size of batches, the greater the number of tasks and responsibilities on the part of the operator. Furthermore, in small firms with variable runs of production, the machine operators carry out programming functions as well as tasks of optimalisation, adjustment and quality control. The number of different tasks also depends on the level of education and skills of the operator, which is slightly higher in small firms. One of the main findings is that new technologies leave room for organisational choices concerning the quality of work. If small firms are to be able to compete in the future much depends on the way they make use of modern technologies. The first concern when automation is introduced is to keep the multi-skill and autonomous character of jobs intact.
