Manual Making of Woodwork Machine Based on Investigation of Accident of Technology Education

The content of study of machine processing practice in Woodwork is consequentially treated as unimportant. The cause of the problem are danger of machine processing, decrease in number of time of class, many of number of students in one class and others. The accident caused by the woodwork machine has the possibility to cause a serious accident. If the woodwork machine is used by the comprehensible manual corresponded to student's recognition process, it is safe. The analysis of a past accident case must be made the best use for the manual enough. The manual must prevent wrong operations of the students. In this research, the case with the occurrence of the past accident in Woodwork in Technology Education and questionnaire investigation to the teachers were analyzed. The manual that the student is able to operate the woodwork machine safely and appropriately based on these analyses was examined. The manual does not only show correct work procedure, but also shows the principle mechanism chart of the processing and the dangerous operations
