Surface quality and geometric accuracy are important evaluation indexes for machining quality of parts. In order to realize the quality control of nozzle honing, it is necessary to clarify the influence of honing parameters on surface roughness, dimension accuracy and shape accuracy. Cutting force is an important process parameter, which has an important influence on machining quality. The research on the influence of honing parameters on cutting force contributes to explain the honing process and the influence of honing parameters on machining quality. Therefore, the cutting force during honing was analyzed and modeled, and the influence of honing parameters on cutting force was clarified, and then the influence law of honing parameters on surface roughness, bore diameter and shape accuracy was explored. Finally, according to the processing requirements of fuel nozzles, the honing process optimization was carried out and the optimal processing parameters were obtained.

“…The reason is in fact that the prediction of processing accuracy in an automatic grinding cycle with switching feeds` program speeds cannot be performed using a one formula because the treated surface is repeatedly formed with forces and cutting depths changing at each revolution along the entire length of the treated surface under the influence of unstable technological factors. Many scientists have worked on above problem; there are some works which can be distinguished [2][3][4][5][6][7][8][9][10].…”

Parts’ processing on circular grinding machines is carried out according to the specified stepwise control cycles of radial and axial feeds, which are laid down in the control program (CP). Despite the precise positioning systems, modern CNC circular grinding machines have a variable compliance of the technological system along the processing length. It causes different cutting depth and occurrence of various errors in dimensions of the diametric surface. Also, the dimensions error increases due to the fact that the processing of parts batch is carried out in unstable conditions and under the influence of different variable factors, which can include allowance fluctuation, blunting of the wheel grains, changes of the wheel diameter and the contact area of the wheel with the workpiece, etc. However, there are still no means of control developed CP, which include cycles of cutting modes, to ensure the accuracy of parts batch` processing. This article describes the digital twin (DT) of the circular plunge grinding with CNC, which allows simulating layer-by-layer metal removal during the whole grinding cycle by calculating the cutting depth on each workpiece revolution under various combinations of unstable processing conditions and variable compliance of TS. Modeling of layer-by-layer allowance removal is performed in several sections of the treated surface; these sections have different compliance. At the end of the grinding cycle in the DT the processing accuracy is estimated on the basis of the obtained values of radii dimensions in all sections of the processed surface. The introduction of DT allows speeding up the CP development, reduce the time of launching CP in production, and increase the productivity of circular grinding operations with CNC by optimizing the cycles of the cutting modes while ensuring the specified processing accuracy.
