Abstract
This paper presents a model of the formation process of surface zones of external cylindrical grinding with traverse feed at a computer numerical control machine (CNC). This article, have investigated modelling features of the grinding process in reverse zones. On the basis of the model of grinding surface formation a detailed step by step calculations of the current values of the actual radial feed and radius dimension in different areas of a treated surface is presented. The model allows maintaining calculations with presence of the initial radial runout of the workpiece for estimated automatic cycle of radial and axial feeds changing and other technological parameters.
Highlights
At present in the field of automated manufacturing and industrial automation there are no models, methods and soft ware which allow to forecast the accuracy of the parts processing during cylindrical grinding with traverse feed on control machine (CNC) machines
The aim of work is to increase the efficiency of use the cylindrical grinding machines with CNC by designing models and method which allow to make an analytical calculation of the depth cut actual values and forecast the change of radius dimensions of the treated surface in reverse and non-reverse areas under the influence of various variable factors and grinding conditions
Grinding wheel is deepen into the radial program feed value ∆tпk,i,z ; due to the presenceof initial radial beating of the workpiece is calculated on each k-th radius of the part, i-th turn of the part and z-th stage of the grinding cycle
Summary
At present in the field of automated manufacturing and industrial automation there are no models, methods and soft ware which allow to forecast the accuracy of the parts processing during cylindrical grinding with traverse feed on CNC machines.
