Abstract

Design and Development of a Chamfering Machine for Stainless Steel Pipes to Be Joined. One of the key aspects of technological advancement is to facilitate human activities. The design and development of this chamfering machine aims to simplify the process of welding or joining stainless steel pipes and to accelerate the overall work process. Stainless steel pipes are a type of pipe made from stainless steel, an alloy containing iron (Fe), chromium (Cr) of at least 10.5%, along with other elements such as nickel (Ni), molybdenum (Mo), and manganese (Mn). Chamfering is a technique or machining process used to create grooves, recesses, or holes in a workpiece, often applied to metals, wood, or plastic.

The operation of this chamfering machine is supported by several mechanical components, including an electric motor, sandpaper, pulleys, V-belts, bearings, shafts, and a frame. The methodology implemented includes the creation of a simple chamfering machine prototype, testing on stainless steel pipes with five samples for each method (manual and machine), and measuring the chamfer depth and processing time. The results show that the chamfering machine can reduce work time from an average of 140 seconds (manual) to 80 seconds, achieving an efficiency of 175%. In terms of chamfer depth, the machine method provides more consistent and closer-to-ideal results (average 1.496 mm) compared to the manual method, which shows greater variation with an average of 1.57 mm.
