Abstract
To ensure the quality of products and efficiency of machining and to protect the machine tools from damage in high speed working conditions, one of the key solutions is to smooth the feedrate profile at the corner of two adjoining moves. In the paper, a vector based look-ahead algorithm is presented for feedrate smoothing at trajectory corner by interpolating adjoining moves simultaneously. By analyzing and simulating, it is verified that this algorithm can realize good machining quality and smooth velocity at the corner of the tool path with high speed.
