Analysis of square threading process by using response surface methodology

Threading has become quite popular in recent years as an alternative to tapping or other forms of threading because of diversity and complexity of parts and flexibility of the process in industries such as biomedical applications, aerospace and die-mold manufacturing. However threading is one of the complex and critical operations due to its tool geometry. To analyze the threading parameters by means of design of experiment concept wit response surface methodology. The full factorial design is used for experimental design. The three levels of spindle speed and depth of cut are used as an input parameter. Similarly responses are material removal rate, surface roughness and forces such as feed force, trust force and cutting force during threading operation. The main objective of this study is to evaluate the difference between the Square thread and pilot v grooved square thread to maximize the surface finish of threading. And also to determine the responses, such as Material Removal Rate (MRR), Surface Roughness, and Forces for square thread and the pilot grooved square thread. Based on the analysis pilot v grooved square thread is better than square thread. As a result in Square Thread and pilot v grooved square thread responses such as Feed Force, Thrust Force, Cutting Force, and MRR and is high. Surface Roughness is high only in Square Thread compared with pilot v grooved square Thread. (C) 2020 Elsevier Ltd. All rights reserved.

Automated summary

The study aims to analyze the difference between Square thread and pilot V grooved square thread in terms of maximizing surface finish, as well as determine responses such as Material Removal Rate, Surface Roughness, and Forces. The analysis shows that the pilot V grooved square thread is superior to the square thread, with higher levels of various forces and Material Removal Rate, and lower surface roughness.
