Description:

The article presents the association of the output signals of the grinding process with the machining parameters. The article focuses on assessing the suitability of grinding force signal and acoustic signal acquisition for different process conditions. In the first part of the article the kinematic contact of abrasive grain with the workpiece analysis was carried out. By analogy to the micro-cutting process, geometric analyses are presented and the process parameters that have a major impact on the grinding zone load are indicated. Analytically it has been shown that elementary grinding speeds (wheel and workpiece speed) and grinding depth have a significant effect on recorded signal values. The work also presents a set of factors and phenomena that are sources of acoustic emission impulses in the grinding process. For a selected range of grinding parameters, an experimental verification was performed. The article presents the highly correlated relationship between grain penetration depth (maximum uncut chip thickness) and grinding force components, as well as the effective value of acoustic emission. The output signals of the grinding process were also compared, indicating the advantage of the acoustic emission signal above the grinding force in terms of the reaction speed (and lag) of the sensors to the phenomena occurring in the grinding zone.
