Investigative Study of Skill Education in the Non-Ferrous Metal Casting Manufacture
The purpose of this study is to clarify the current condition of skill education systems, in addition to accompanying harmful ones. Moreover, we investigated the work loads, working environment and redesigned-skill education systems. As a result, the work of controlling temperature and the ignition required high skills, so aged workers with high skills performed them. In addition, the workers often had to take a half-crouching position during operation. The noise exposure level was over 95 dB throughout a day. Therefore, it was hard to communicate with each other, and there was a problem with on-the-job training for young workers. As for skill education, it was difficult to create a manual on their skills because the seat-of-the-pants skills differed among skilled workers. From the results of this investigation, the harmful effects of education were as follows: 1) the work of high skills is accompanied with high work loads, 2) it is difficult to conduct OJT because of noise, and 3) skilled workers have difficulty in training young workers. As the redesigned-skill education, three countermeasures were devised. For the first, the skills were easily learned by work improvement. The fuel was changed from heavy fuel oil to gas in the object factory, so the adjustment works with high work loads were rejected. A new gas furnace managed the ignition, air and fire power adjustment collectively by means of the control panel. Secondly, the skill maps were made. All of workers compared skill/technical level with the years of experience and reconfirmed the number of years until acquiring those skills. Thirdly, the working environment created to educate smoothly. The noise decreased 10dB in burning by changing from the fuel to gas, so it was easy to provide skill education and training.
