Abstract

In the traditional laboratory sessions of the Manufacturing Processes Laboratory (INME 4056) in the Mechanical Engineering Department at the University of Puerto Rico campus Mayagüez, the experimental practices with lathe and milling machines lack pre-exposure to the processes before the session when the students work with the final project part. This leads to significant errors in the targeted dimensions in the final project part, which also can affect the geometrical tolerances process learning, one of the important assessments to evaluate at the final of the laboratory class. This paper examines how pretraining sessions, following the philosophy of spaced practice, helps to improve the geometrical tolerance in the final part, and the corresponding learning process. The comparison was carried out between two different laboratory sections, one section experimented with the extra training session and the other one only performed the regular training. This paper presents the results from Spring 2019, including qualitative measures, particularly in tolerance gap reduction. The statistical analysis used was a two-sample T-test, and the p-value was 0.443 which indicates the differences between all the % errors of the featured between control and experimental section are not significant.
