机械制造技术基础培训课件(英文版)内容提要：
Machining accuracy and machining error
Machining accuracy：The degree of the practical dimensions after machining conforms to the desired geometrical parameters.The higher the degree conforms, the higher the machining accuracy.
Machining error：The degree of the practical dimensions after machining deviates from the desired geometrical parameters. The size of the machining error denotes the size of the machining accuracy.
“Machining accuracy”and“Machining error”  are two different concepts to evaluate  the accurate degree  of the part geometries. In production practice, the accuracy is ensured by controlling the machining error or active adapting method 。
