INTENSITY AND QUALITY IMPROVEMENT OF HARD AND SUPER-HARD MATERIAL SAWING BY TRANSFERRING PLANE CIRCULAR MOTION TO BLANK
Abstract
The paper considers an experimental evaluation of the influence of a plane periodic circular motion which is transferred to a blank on the intensity of its sawing and quality of its machined surface. Description of a modernized industrial sawing section has been given in the paper. The section is used for sawing various types of specimens (jasper, quartz glass, corundum) as under conventional machining conditions so while transferring them a circular motion along a closed path with a shape being like an ellipse. It has been established that in comparison with machining under conventional conditions transfer of such motion to a blank makes it possible significantly (by 2.5-3.9-fold) to improve sawing intensity and simultaneously to reduce Ra value of their sawed surfaces by 1.9-3.0-fold. The obtained results have allowed to make a qualitative description of a mechanism which reveals an influence of a blank circular motion on higher intensity of its sawing and quality of the machined surface.
