Example of Revision of Company Standards for Technical Drawings of Mechanical Engineering According to Revised JIS B 0001

Abstract

　Japanese Industrial Standards (JIS) B 0001 (Technical drawings of mechanical engineering) have a high degree of convenience and usability. They were revised on 20 May 2019; however, inappropriate uses of drawing rules remain, including errors in terminology, misuse of drawing rules, and the existence of exceptions. Before revising the company standards for technical drawings of mechanical engineering according to the revised JIS B 0001, we searched the points that deviate from drawing rules and examined the revised JIS B 0001 to clarify basic standards. We report an example of revision of company standards for technical drawings of mechanical engineering on the basis of our examination.
