Tool edge radius plays a significant role in affecting the surface integrity of machined products. The vast majority of existing research, however, takes no account of the effect of tool edge radius in the evaluation and modeling of machined surface roughness, an essential indicator of surface integrity. The present study fills this important research gap and has performed a total of 45 turning experiments on Unified Numbering System (UNS) A92024-T351 aluminum alloy with carefully selected cutting tools with three levels of tool edge radii. This article describes the experimental setup and measurements of tool edge radius and machined surface roughness. …

In order to facilitate self-monitoring interventions designed by the Faculty of Computer Science Universitas Indonesia a web-based self-monitoring tool was created. This paper aims to evaluate the tool regarding its usability and user-experiences prior to its wide adoption. The System Usability Scale (SUS) and the User-Experience Questionnaire (UEQ) were used to evaluate the self-monitoring tool. The tool was implemented in a Human-Computer Interaction course during odd semesters, and the evaluations were taken by the participants of the course. The evaluation results were analysed to help determine whether the tool needs to be enhanced or improved. Based on the results, a …
