Toplam 185 atıf DOI
Monitoring of the cutting area with different type of sensors requires confirmation for composing sensor fusion to obtain longer tool life and high-quality product. The complex structure of machining and interaction between variables affect the influence of parameters on quality indicators. Using multiple sensors provide comparison of information acquired from different resources and make easier to decide about tool and workpiece condition. In this experimental research for the first time, five different sensors were adopted to a lathe for collecting data to measure the capability of each sensor in reflecting the tool wear. Cutting forces, vibration, acoustic emission, temperature and current measurements were carried out during turning of AISI 5140 with coated carbide tools. Considering the graphical investigation, the successes of sensors on detection of progressive flank wear and tool breakage were investigated. Besides, the effects of cutting parameters on measured variables were interpreted considering graphs. According to results, temperature and acoustic emission signals seem to be effective about 74% for flank wear. In addition, fuzzy logic based prediction of flank wear was performed with the assistance of temperature and acoustic emission sensors with high accuracy which demonstrates their availability for sensor fusion. Tool breakage occurs instantly which can prevent with the assistance of sensor signals and tangential and feed cutting forces, acoustic emission and vibration signals seem as reliable indicators for approaching major breakage. Sensor fusion based turning provides confirmed information which enables more reliable, robust and consistent machining.

Composites have excellent material properties such as lightness, rigidity, and strength with reinforcement of specialized materials to serve an extended field in engineering. Meanwhile, some restrictions due to the production process lead to poor machinability characteristics and show reduced surface quality, excessive cutting temperature, and tool wear. The principal aim in this study is to research the machinability characteristics of Cu matrix reinforced by B and ceramic CrC powders during dry turning operation. In addition to reinforcement ratio, cutting speed, feed rate, and depth of cut were taken into consideration according to Taguchi L8 orthogonal array in the experimental plan. Seemingly, reinforcement ratio is the governing factor over turning parameters on flank wear, surface roughness, and cutting temperatures. For the secondary effect, cutting speed and feed rate have contributing impact on cutting temperatures and surface roughness, respectively. Lastly, reinforcement ratio has significant impact on chip formation since deformation mechanism in the material is changed with cutting initiation. Accordingly, new additives reveal unique structure which is intriguing and need to be discovered for measuring the machinability behavior of metal matrix composites.
