After conducting the precision machining Toronto, most of the surface finish are rough or with poor quality because of various factors such as chips sticking back to the work piece, BUE or built up edge which is still considered unstable. All materials are affected but the poor finish. Other factors may also include a machine that is not maintained properly and metalworking fluids used in the operation is already exhausted. There are various ways and methods that can be used or applied in order to avoid the issue of poor surface finish. Here are some of the suggested options that can be done directly on the machine.
- The first thing you should try is to increase the SFM speed, more so on Carbide. Doing this will help lessen the built up edge or BUE.
- The feed per evolution which is measured in IPR unit or inch per revolution should also be lower. If this is done then the flak wear will be more likely minimized as well.
- The angle of the top rake should also be higher.
- Next thing you could try is to buy chip curler or chip breaker and add this to the process.
- Last thing one should try is increasing the radius of the tool nose.
BUE or built up edge is influenced by the following there major factors – tool geometry, surface footage and material chemistry. Tool geometry aims to cut or slice but never to scrape, surface footage is when the chip is hot due to the slow speed which results to higher BUE and material chemistry is something that can be undone since the material is already chosen.
