Abstract: The mechanism of chatting on grinding may be said not having been got fully understood so far, some of which are unidentified particular ones during cutting work. While the problems of ground vibration are produced in the plant, practical reserching and reform ,work will no doubt be more difficult than in occasion of cutting manufacture. Starting from indirect study of ground vibration marks of the surface machined, this paper presents the concept of ground vibration marks spaced around the circumference of circle and spaced along the axial length. It solves the measurement; problem of surface vibration marks in the production. Some main technological parameters influencing vibration marks can be analysed correlatively and thus given the regression equation by means of statistics and high sample size. Interdependence of surface roughness and surface marks can be also explained with a hyperbola. There are three kinds in the turning direction of ground surface marks, that is the straight grained and left-hand and right-hand surface marks. At the same time ground surface marks of the cylindrical cross nets are found and its recall is shown as 12.5%. The effective control of the technological methods of ground surface marks are pointed out by the orthogonality experiment during the working process of cylindrical and internal and centreless grinding.
