Fundamental Investigations Into Burr Formation and Damage Mechanisms in the Micro-Milling of a Biomedical Grade Polymer

摘要: The demand for micro-machined polymer components has been rapidly growing a number of years in various diverse applications. These often require high surface finishes and excellent dimensional accuracies, meeting these specifications requires deeper understanding material behavior cutting performance during micro-machining. A lack published literature relating to machining increases the production challenge as strategies employed are based on trial error with heuristic solutions developed. This work explains outcomes by focusing study damage mechanisms encountered micro-machining biomedical grade polymer. importance removal mechanism is highlighted up-milling shown produce superior finish average. role speed feed generation machined surfaces examined suboptimal settings unwanted thermal infl...
