Determination of Displacements on a Cutting Disc During Sawing Process

In this paper, the displacement signals of a saw disc during cutting of square shaped metallic profiles are examined. The most important aspects of the study for sustainable manufacturing are reducing maintenance costs by preventing tool damage and ensuring the continuation of production by avoiding interruptions. Analysis of lateral displacements during cutting process can help controlling the cutting and circular speeds of the disc to prevent any possible damage. An experimental setup is built to collect lateral displacements. During experiments, square shaped metallic profiles are cut with different cutting parameters. The displacement signals are measured by a laser based electronic system and a detailed time-frequency analysis of the data is performed to determine the frequency components carrying significant information about the cutting process.
