List and explain the factors that contribute to poor surface finish in machining operations. Hint: By the student. Recall, for example, in turning or milling, as the feed per tooth increases or as the tool radius decreases, the roughness increases. Other factors that contribute to poor surface finish are built-up edge, tool chipping or fracture, and chatter. By the student. Recall, for example, in turning or milling, as the feed per tooth increases or as the tool radius decreases, the...

2. A major home appliances company produces compressors for their refrigerators in one of their plants. The most critical part of a compressor is called crank which is made from cast iron. The surface quality of the crank directly affects the energy consumption and the noise level of the refrigerator Therefore, it has utmost importance in the compressor production. The process of crank manufacturing starts with sand casting process. Casting department is a separate building only dedicated to casting and...

BASED ON REAL DATA TAKEN BY AN OPTICAL 3D SURFACE PROFILOMETER The surface of a part has a profile given by the y-values (distance to the surface from a reference centerline) vs. x-values (distance along the surface from a reference starting location) shown in the enclosed "txf file. Before fikering to remove the surface waviness, the yvalues are as shown under the column labeled "nfilered yvalues". After propar filtering to remove the surface waviness, the yalues are re-caleulasted, and shown...

Building a kayak using the composite method is a very labor-intensive process. In the Fabrication Department, the kayaks go through several steps as employees carefully place layers of Kevlar® in a mold and then use resin to fuse together the layers. The excess resin is removed with a vacuum process, and the upper shell and lower shell are removed from the molds and assembled. The seat, hatch, and other components are added in the Finishing Department. At the beginning of...
