Investigation of the influence of certain factors on the quality of processing during hard grinding

Abstract

Abstract The surface roughness of wood products has a direct impact on many technological and operational properties of parts as a whole and is an important production factor, which is associated with the consumption of materials and the technical and economic efficiency of many technological operations such as gluing, grinding, varnishing, etc.We must not forget about the aesthetic properties of wood - reflective and absorbing ability, which is directly affected by surface roughness. The urgency of the problem of obtaining the required quality of the treated wood surface is now becoming increasingly important in connection with the increasing requirements for the quality of woodworking products and obtaining the greatest economic effect for the enterprise. A polished surface is formed as a result of the simultaneous action of many factors. The main ones are geometric factors, plastic and elastic deformations that accompany the grinding process.From a geometric point of view, the roughness is created due to the copying of the path of the cutting tool of a certain geometric shape on the wood surface. Plastic and elastic deformations occurring during the cutting process strongly distort the microrelief resulting from the action of geometric factors.
