Development and Designing an Adjustable Metal Cut off Machine

Abstract

Nowadays metal-cutting equipment is in demand in the market because of the different construction process not only on this infrastructure but also on the training process of different schools that offer qualification under the metals and engineering sector. Cutting these metals may also affect the budgetary cost of the output. Cut off machines are commonly used for this purpose. Cut off machines that are produced in the industry seem to be more expensive not just because of the parts but also because of the use of the consumption of the disc. Cut off machines uses #14 cut off disc. After using it there is always a residual disc that is having a diameter of 12 cm. This residual disc is almost the size of the disc of an angle grinder which is having a #7 cutting discs that almost cost 80 pesos. Also, this cut off machine cannot cut at your desired angle. Upon this issue, the researcher came up with developing and designing an adjustable metal cutter that can maximize the use of the disc and can cut at a different angle, As the result of the project almost 6 cm diameter was the maximum size of the waste disc. This machine can be used in the metals and engineering sector, specifically in SMAW, welding shops, construction companies, and others related to metal workings. This has also become economical because some parts of the machine are recyclable materials. A full factorial design of the experiment is selected for experimental planning and the analysis of variance (ANOVA) has been employed. Upon the evaluation, the adjustable metal cut off machine passed the level of (1) acceptability (2) functionality and (3) safety of the product.
