If you could perhaps offer a definition as well as an explanation of the idea of "expandability" in relation to picking devices that are near to one another.
A furniture company that makes upholstered chairs and sofas must cut large quantities of fabrics. Many of these fabrics are strong and wear-resistant, which properties make them difficult to cut. What nontraditional process(es) would you recommend to the company for this application? Justify your answer by indicating the characteristics of the process that make it attractive.

- A turning machining experiment was performed at the UCSI University's Mechanical Engineering workshop using a lathe machine with palm oil as lubricant. It was observed that during the entire machining, the technician set cutting tool perpendicular to the direction of tool motion. A further investigation revealed that the tool rake angle was 25° while the dynamometer results' analysis showed that the frictional force and the normal force to the friction was 5 kN and 25 kN respectively. Analyze how the chip thickness will be affected if the machining is performed without any lubricant and the frictional force is increased by 100 %. Assume that, all other parameters were kept constant during the entire operation for both machining with lubricant and the dry machining process.arrow_forwardWhat are assessments that measure strength, speed, agility, or high-speed strength?
