Highly Efficient Milling on the Example of Selected Machining Strategies

Abstract

The pursuit to achieve a broadly defined optimisation of the manufacturing processes imposes the use of the in- creasingly innovative machining methods. The increase of the machining efficiency, assuring a high surface qual- ity as well as precision of dimensions and shapes, necessitates the search for new methods to meet the demanding requirements, apart from the development of materials used for the working parts of tools, wear-resistant coatings or improvement of the cutting tool point geometry. One of the methods to improve forming by machining is the optimisation of the machining strategy during the manufacture of the components having complex shapes. The progress in this field is particularly noticeable along with development of the software for machining on multi-axis machines. This article presents the results of tests for the impact of machining strategy on passive force, cutting torque, material removal rate, topography of the obtained surface and the shape of chip resulting from the alu- minium alloy milling. The tests were performed by comparison of the classic strategy available in the NXCAM system to the iMachining technology.
