“…It is worth commenting that in relatively new models of the grinding process [39][40][41] the grinding zone is still limited only to the entry part. Such an approach is especially appropriate for models explaining the energetic aspects of the grinding process.…”

a b s t r a c tThis paper presents an advanced probabilistic model of the grinding process considering the random arrangement of the grain vertices at the wheel active surface. The general model has been developed based on well-founded assumptions. The process of shaping the ground surface roughness, the probability of contact between the grains and the work-material as well as the undeformed chip thickness are described along the grinding zone. Eight special models obtained by substituting general relationships with special functions are also presented. The calculations performed for the special models lead to interesting conclusions relating to the real length of the grinding zone, which is considerably longer than the nominal (geometric) contact length, taken by default in most known approaches.

Politeknik Dergisi, 2017; 20 (4) : 815-825 Journal of Polytechnic, 2017; 20 (4) Investigation of the Effect of Cutting Parameters on Surface Roughness by a New Type of Plane Surface Grinding Mechanism (YTM) ABSTRACTThe new plane surface grinding mechanism (YTM) is a new plane surface grinding mechanism obtained with the mechanism developed. In the traditional plane surface grinding mechanism, the wheel has only a single rotation. The wheel rotates circumferentially around its axis. In YTM, on the other hand, there are two rotations. The first rotation is the same with the traditional grinding mechanism, which is the circumferential rotation. The other rotation is the newly developed axial rotation, where the wheel rotates around itself perpendicular to its radial axis. This totational is called axial rotation. Thus, the wheel has two rotations. Experiments were made for this newly developed method using various parameters and surface raughness (Ra) values were measured. Five wheels with different kinds were chosen. Workpieces were grinded with all these different combinations and effects on surface roughness were investigated. As a result, YTM produced smaller surface roughness values than the traditional method. Surface roughness values were very close in every part of grinded work pieces. YTM is also very low in cost and can be adapted to all milling machines and CNC machines. It can be safely said that YTM is better than the traditional system because of all these directions.

Abstract. The complex dynamics of grinding repeatedly cause critical or unstable process conditions. For a better understanding and prediction of such occurrences, the dominant excitation phenomena need to be identified and their interrelation with the system dynamics have to be analyzed.Based on measurements of the excited frequencies in several operation modes of the grinding machine, the grinding wheel rotation is identified as a major excitation source. Further analysis of the grinding wheel surface displays three main components that define the excitation frequencies of the system; these are the eccentricity, waviness and roughness (also named wheel topography). Moreover, the wheel topography and thus the excitation frequencies can change over time due to excessive wear.Following the experimental results, a grinding wheel topography and wear model are developed and included in an integrated simulation of tool grinding. The analysis of the calculated cutting forces in the frequency domain confirm the excitation due to the grinding wheel topography.Firstly, this work has extracted the grinding wheel as a prominent excitation mechanism and reproduced it with the developed grinding model. Secondly, we have evidence that a complete description of the complex grinding process is only possible when considering the interdependence between system dynamics, wheel kinematics and the grinding process.
