The results of introducing the `Teach Each Other' learning system, it was revealed that: (1) the average test scores of trainees were improved, (2) the grades of the trainees with poor pre-test scores were improved, (3) the ratio of disqualified trainees, i.e., trainees who made a post-test score of less than 70 points was reduced, and (4) engineers with uniformly higher test scores could be fostered. Since the hardness of the material being cut has no effect on the cutting speed, Wire EDM can be used to cut a wide range of conductive materials including hard metals or materials that are fairly brittle and would be damaged by other machining processes. Different machine learning techniques that can be utilized to predict students’ GPA are briefly outlined in section 3. However, Electrical Discharge Machining was not started uni-versally until 1943 when Russian scientists learned how the erosive e ects of this technique could be controlled and used for machining purposes.
