Evaluation of a constructed manual drilling machine for small scale operation

Abstract

In this study, a critical analysis was carried out on the various classes of drilling machine to establish their performance based on their applications and also, to have comparative evaluation between electrically driven drilling machines (EDDM) and manually operated drilling machine (MODM). In the ancient days, flat punch was used to make holes on materials, but due to advancements in technology, drilling machines are now being used instead, making the work easier and faster. There are different drilling machines, including radial, sensitive, upright, gang, deep hole, multiple spindles, and automated drilling machines. Also, an indigenous table-mounted manual drilling machine was fabricated, with a rigid and robust structure but flexible to operate enhances the production of the hole on solid materials such as metal, wood, Teflon, and other materials. This evaluation has provided an enormous privilege for the manual operated drilling machine to be employed for small scale operation (SSO) and to serve as a relief to the less privilege communities. More so, this simple method would save the end-user from the unnecessary expense on fuel and expensive bills.
