Bachelor thesis: Impact of different green body brushing patterns on insert quality

Sandvik Coromant in Gimo, Sweden offers a thesis project within the area of automation of insert blank brushing.

Introduction

Sandvik Coromant in Gimo, Sweden, with approximately 1,300 employees, is a world leader in the manufacture of cemented carbide tools for machining metallic materials. Our customers are found in the metal processing, automotive and aircraft industries, and our aim is to meet the markets' more stringent demands for new precision products with great durability.

The tools production in Gimo is the largest production unit for tools for turning, milling and drilling in Sandvik Coromant. Our ambition is to be recognized as the world’s best production plant in this category. The Gimo production unit has recently started a project prestudy on developing an automated solution for brushing unsintered insert blanks removing the edge flash from pressing.

Background and scope of the project

The unsintered pressed blanks, called green bodies, have historically been brushed by hand, which is time-consuming, operator-dependent and unhealthy. Therefore, Sandvik recently started a project developing an automated solution using a collaborative robot that removes the edge flash by brushing, which improves edge quality and minimizes the risk of damage during the top and bottom grinding.

Your assignment is to develop and understand the fundamentals of the brushing itself. Find the common grounds and find out what brushing patterns are optimal for the different geometries.

Work description

Working together with the pressing and grinding department to understand the impact on how different brushing patterns can improve insert edge quality.

The work shall start with a planning phase including a literature study involving other production units, defining possible problems, and making a project plan for the practical tests. A realistic test plan will be an essential part of the project plan as the number of parameters are many and the available time is limited. After the practical test has been performed, in one or more loops, the work shall be summarized in a thesis report and a presentation of the work shall be made on site.

Student background

Bachelor’s program in mechanical engineering, material science or equivalent. Preferably basic competence of CAD/CAM and some experience working with robotics. Fluent in both verbal and written Swedish and English.

At Sandvik Coromant, we believe that diversity of experience, perspective and background leads to a better environment for our employees, our business and our customers. We’re looking forward to meeting you!

Duration of project

The thesis project lasts 10 weeks, starting in March 2022. The location is in Gimo, Sweden.
