Modeling Relationship Between Different Stages of Cylindrical Grinding Process with Axial Feed in Reversal Zones

Operation efficiency management for cylindrical grinding with axial in-feed (for instance, internal and external grinding) at a numerical control machine (CNC) is performed with an automated adjustment of radial and axial in-feed within a staged cycle depending on the amount of the remaining part of allowance. However, grinding in reverse and non-reverse areas is performed with different cutting modes due to a number of factors: the presence of cylindrical grinding with radial in-feed at penetration stage at the beginning of a working path, necessity of reverse switch of axial in-feed, and the cutout of axial in-feed at penetration and reverse switching stages. As a result, the dynamics of actual radial in-feed and cutting force in all sections of a treated surface is significantly different in terms of grinding methods and value. That is the reason why treatment precision may vary depending on the length of a treated surface. The article describes the standardization processing steps of the scientific method in the reverse zones and shows a functional relationship interaction the actual radial feed, programmed radial feed in axial feed grinding. Also, there are data on how elastic deformations change the axis of the circle at all stages.
