Grinding is a critical surface-finishing process in the manufacturing industry. One of challenging problems that specific grinding energy greater than ordinary procedures, while efficiency lower. However, an integrated model and analysis distribution during still lacking. To bridge this gap, time history first built to describe cyclic movement air-cuttings, feedings, cuttings. Steady transient ...

We study the monotonicity properties of solutions in the classic problem of fair cake-cutting — dividing a heterogeneous resource among agents with different preferences. Resourceand population-monotonicity relate to scenarios where the cake, or the number of participants who divide the cake, changes. It is required that the utility of all participants change in the same direction: either all o...

The objective of this article is to design and characterize the technical performance agricultural residue grinding function integrated into operation a multi-purpose cereal thresher. For farmer, equipment will have advantage realize out threshing, grinding, water pumping. Water pumping allowwatering residues after their grinding.The Functional Analysis (FA) was used identify new useful functio...

Abstract As one of the mainstream equipment fully mechanized mining equipment, shearer is a large complex system with functions breaking coal and transporting coal. It an important milestone for China’s industry to move towards modernization mechanization. In order adapt working environment better meet needs social development, optimization spatial structure bearing capacity machine has become ...

Vibration is an inevitable phenomenon in the coal cutting process and severe vibration leads to efficiency loss for equipment. To understand impact of on equipment explore measures improve stability, dynamic response analyzed. The shearer drum, which always undertakes task source working process, established with finite element method relations between performance characteristics are Hydraulic ...

In this study, turning operation of Monel K500 copper-nickel super-alloy was evaluated. Ceramic cutting tools with two different cutting noses (conventional and wiper) were utilized. At first, the experimental tests were designed by using central composite design method. After implementation of the tests, the statistical models for output data (surface roughness, cutting force, and flank wear) ...

We consider the problem of fairly dividing a two dimensional heterogeneous good among multiple players. Applications include division of land as well as ad space in print and electronic media. Classical cake cutting protocols primarily consider a one-dimensional resource, or allocate each player multiple infinitesimally small “pieces”. In practice, however, the two dimensional shape of the allo...

 In the present study, an attempt has been made to experimentally investigate the effects of cutting parameters on cutting force in end milling of AISI 304 steel with solid carbide tools. Experiments were conducted based on four factors and five level central composite rotatable design. Mathematical model has been developed to predict the cutting forces in terms of cutting parameters such as he...
