There are many factors effective on performance of the laser cutting process. Identification of more effective factors requires which will give the significant effect on the cutting quality of materials. In recent years the researchers have explored the number of ways to improve the quality of cutting in the different lasers. This paper reviews the research work carried out so far in the area o...
Prediction of cutting forces is very important for the design of cutting tools and for process planning. This paper presents a fuzzy modelling method of cutting forces based on subtractive clustering. The subtractive clustering combined with the least-square algorithm identifies the fuzzy prediction model directly from the information obtained from the sensors. In the micro-milling experimental...
This paper presents an mathematical model that establishes the relation between the relevant cutting process parameters and surface quality, cutting forces and rate removal, in deburring process. The construction of cutting tool that one use in determining the experimental data is also presented. The mathematical model is determined by using multifactorial analysis. Directions towards the optim...
In this paper we consider a cutting process for random mappings. Specifically, for 0 < m < n, we consider the initial (uniform) random mapping digraph Gn on n labelled vertices, and we delete (if possible), uniformly and at random, m non-cyclic directed edges from Gn. The maximal random digraph consisting of the uni-cyclic components obtained after cutting the m edges is called the trimmed rand...
Predicting the main cutting force during turning is of great importance as it helps in setting the appropriate cutting parameters before machining starts.Again, optimization of cutting parameters is one of the most important elements in any process planning of metal parts as economy of machining operation plays a key role in gaining competitive advantage. This paper presents an experimental stu...
This paper presents a study the effect of nose radius (Rz-mm) on cutting force components and temperatures during the machining simulation in an orthogonal cutting process for titanium alloy (Ti-6Al-4V). The cutting process was performed at various nose radiuses (Rz-mm) while the depth of cut (d-mm), feed rate (fmm/tooth) and cutting speed (vc-m/ min) were remained constant. The main cutting fo...
X-ray diffraction, optical microscopy and microhardness testing have been used to study properties which develop in micro-cut AISI 1045 steel. The influence of the ploughing effect on residual stresses, surface deformation and work hardening, and the tool quality were investigated. Tensile residual stresses, caused by the heat generated in the material during the cutting process, were observed ...
The laser cutting parameters are dependent on the beam characteristics, the cutting rate required, the composition and thickness of the material to be cut, and the desired cut edge quality. The laser cutting process and cut quality depend upon the proper selection of laser and workpiece parameters. Deficiencies in cutting quality may be related to the slow process drifts and disturbances that a...
