Mathematical modeling of the surface roughness of the grinding wheel during straightening

Purpose. Research on the mechanism of influence straightening conditions grinding wheel, including relative oscillations wheel and a multipoint diamond dresser, roughness ground surface other machining results. Methodology. Straightening with dresser is process high-speed destruction hard, abrasive material its bond under instantaneous forces, grains hard crystal. During straightening, total component normal forces causes correspondingly less elastic deformations in tool system, which increases accuracy geometric shape working surface. Findings. The research results make it possible to determine parameters workpiece find ways control increase efficiency process. Originality. regularities state have been established. paper shows that initial arrangement along determined by characteristics. When hit tool, some vertices are chipped off, as result density grain outer increases. was further developed direction non-uniform character location grains. distribution position at depends conditions. Since removal allowance carried out most protruding vertices, then, consequently, will depend their for straightening. Practical value. Application obtained work, namely, mathematical modeling during makes calculate parameter work also level chipping conditions, particular, value axial feed tool. In this case, lower stresses arise bond, works harder one. affect stability self-sharpening zone. This determines significant role
