For lathe machining, pre-processing of the CAD data in Computer Aided Process Planning (CAPP) is essential since it is the link between CAD and CAM. Thus, cylindrical part model orientation is important to be determined in order to ensure the cutting parameter is correctly setup. Without proper orientation during the pre-processing of the cylindrical part model, further calculation and setup wi...

an air filter is a significant element of any mechanical ventilation system. however, the importance and performance evaluation of air filters have not been well publicized and related scientific reports are scarce. in this study, a transportable, off-line, air filter-testing unit (the unit) was designed and utilized to simulate the filter housing of a mechanical ventilation system. the unit wa...

This study investigates the surface topography of deposited thin films versus distance between target and substrate (dTS) inside a laser ablation equipment. The profile rough was obtained by atomic force microscopy data analysis based on power spectral density roughness-length scale (RLS) functions. roughing top film is analyzed considering previous underneath for each consecutive TiO2 Si depos...
