Reverse Engineered Structure of Tool Post aiding Tool Tip Alignment with Work Center

Abstract

In today’s modern time every aspect of life is treading the path of technology. Numerous things of humans’ imagination are turning into reality by some or the other machining processes. The lathe machine tool is the inseparable part of the manufacturing industry as a number of operations can be easily performed on it. The major problem encountered using the lathe machine tool is the alignment of tool tip and the workpiece center. This research work deals with the solution to the encountered problem and presents a modified design of the tool post. In conventional method the height adjustment is done by adding or removing the metal shims or packings. The use of shims/packings is based on the approximation hence it is time consuming and less accurate. New design is consists of a central block which can fixed with the compound rest and two tool holder components which can translate vertically with respect to central block. The height of the tool holder can be adjusted easily by the screw arrangement provided with tool holder. A large force is experienced by the cutting tool, a part from which is transmitted to the tool holder hence different analysis were carried out to check the safety of the design proposed. It was concluded that the proposed design was safe as the amount of deformation and deflection was minimal in comparison to the applied force.
