The Measurement of The Three Components of The Cutting Force During The Turning Process
139-146Views:121We carried out the measurement of the three components of the cutting force as a function of the modification of the depth of cut during the longitudinal turning process. The results show that if we increase the depth of cut, all three components of the cutting force shows increasing tendency, regardless of how much the cutting speed and feed speed were performed during the measurements [1] [2] [3] [4].

Analysis of Abrasion of Hot Metal Powder Spray Coated Layer
342-346Views:196By the application of the tradicional overhead welding and the different powder coating technologies results a new surface with improved abrasion resistance, we can optimize the dimensions of the part or we can rebuild some surface as a kind of repairing technology. By application of this technology we can avoid the replacement of the total expensive parts of the structure. Opposite to the tradicional overhead welding in this case there will be diffusion connection between the raw material and the surface coating, this connection type shows several positive properites. Our goal is to investigate the abrasion resistance of the coating. In this article we would like to introduce our results of the abrasion test by apllication of different powder coatings.

Development of Analysis of Loss Sources of Vehicles
733-737Views:209Vehicle fuel consumption can be significantly influenced by various types of losses such as loss from bearing, aerodynamic drag and rolling drag. It is important to highlight that fuel consumption reduction can be only achieved when those losses are reduced that are induced during the operation.
The aim of our work group is to define the calculation method and the magnitude of the losses of the vehicles. These parameters are intended to be serve as input parameters for future energetic modelling of vehicles.

Calculations of Performance Losses for Automobile Vehicles
210-218Views:230Vehicle-energetic-models are used to analyze the performances and when a comprehensive structure is established even optimization could be done. For these kinds of models, the losses of the vehicles have to be known. These losses could significantly effect of the vehicle fuel consumption. From these losses the rolling resistance, drive elements and aerodynamic drag are discussed. This paper reviews some of the literatures that describes the calculation methods and gives us some idea about the degree of their value. Our further goals are to have an UpToDate loss coefficient dataset and calculation methods for further vehicle-energetic modelling.
