Conversion CL data to NC data using an instinctive method for non-orthogonal table-type 5 axis machines

摘要

Since different types of 5-axis milling machines have their own unique rotation mechanisms, the solutions developed to generate numerical control (NC) data are traditionally targeted toward specific mechanisms and are obtained via specific methods, normally resulting in complex algorithms. In order to resolve this problem, this paper proposes an instinctive method to convert cutter location (CL) data to NC data for non-orthogonal table-type 5 axis machines. The rotational angles of the two rotational axes can be easily derived from the tool-orientation vector, and the coordinates of the three linear axes in the NC data can be easily derived from the rotational angles and coordinates of tool position. Even more, this method enables the development of a generic algorithm for the rotation mechanism of any 5-axis CNC milling machine.
