- Abstract
In a company specialized in the production of V-belts, which use milling to generate the final surface of an assortment of V-belts, we have encountered problems starting from fastening up to milling the rubber. At vulcanized rubber any error makes the workpiece to be rejected without the possibility to fix it, or not even to reuse the material. After we studied the literature from domain, we observed that the cutting issue of vulcanized rubber type 3540 and 3003, is not defined from some points of view, for this reason we made an experiment to observe the behavior of rubber milling at cryogenic and room temperatures, with a cutting speed of 3297m/min at a feed range between 0.0025 mm/tooth and 0.02 mm/tooth. As a result of the experimental study, we observed that for the workpieces that were cooled with liquid nitrogen, the reject rate was reduced down to 20%. We also observed that, at cryogenic temperatures, feed milling had a small influence on the obtained surface quality.
