Abstract
Polymers have existed in the manufacturing scenario for a long time now. However, the surprising part is that the data for metal cutting is still being incorporated for machining of polymers. Polymers are often machined using the tools on the data available for soft materials like aluminum. There is little research done in the domain of machinability of polymers to find out the best cutting combination.
The goal of this research is to analyze six different polymer materials which possess behaviors that are drastically different when compared to each other. We intend to focus primarily on the surface roughness of these materials. The goal is to start with the standard inserts used for machining aluminum and then to incrementally proceed... (More)

The goal of this research is to analyze six different polymer materials which possess behaviors that are drastically different when compared to each other. We intend to focus primarily on the surface roughness of these materials. The goal is to start with the standard inserts used for machining aluminum and then to incrementally proceed further in the research from the results of surface roughness that we achieve. The tool geometry, cutting fluids and cutting parameters are in focus here. The materials are available in the form of cylindrical workpieces, and they will be machined on the lathe, then the surface finish will be analyzed for each run under a microscope. The secondary scope of this thesis is to also measure the tool damage under a microscope and the material removal rate. These secondary measurements can be used to compliment the surface requirement and generate different cases as per the requirement. (Less)
Popular Abstract
The problem statement of this thesis involves cutting six different types of plastics on a machine called a lathe. The plastics have similar geometry and involved plastics like nylon, PVC etc. The project is done in collaboration with a company called Carlsson and Moller which is based in Helsingborg, Sweden. The goal is to see which method of cutting these plastics can generate the smoothest surface finish. The different cutting methods are denoted by different machine speed, using different cutting tools etc. The surface which is cut is then observed under a microscope to determine the surface finish or quality of the cut surface. There are standard methods which we will use for this surface measurement like the Ra value for example. The... (More)
The problem statement of this thesis involves cutting six different types of plastics on a machine called a lathe. The plastics have similar geometry and involved plastics like nylon, PVC etc. The project is done in collaboration with a company called Carlsson and Moller which is based in Helsingborg, Sweden. The goal is to see which method of cutting these plastics can generate the smoothest surface finish. The different cutting methods are denoted by different machine speed, using different cutting tools etc. The surface which is cut is then observed under a microscope to determine the surface finish or quality of the cut surface. There are standard methods which we will use for this surface measurement like the Ra value for example. The end result will be in the form of recommendations for which cutting combination generates the best surface for each of the six plastic materials. We also have a secondary scope for this project which is to investigate how fast we can remove or cut the material under different cutting combinations and to also check the tool damage under a microscope. We will add comments about the secondary observations. (Less)
