Here, all linear axes are theoretically perpendicular (dot product, cos 90 = 0) to each other and directed along the X, Y, Z coordinate, but in working machines, the axes are nearly perpendicular (cos 89.9 ≠ 0) because of the reasons mentioned above. This kind of error can be taken into consideration only by the precise description of the actual kinematics of the machine tool. This paper attempts to develop a generalized error model for the effects of positioning errors of the components of the kinematic chain of a machine in the work space and the results obtained by this model have been verified experimentally. The effect of positioning error has been studied further for the machining of rear hub and an improvement in quality of hub has been observed.

Now a day’s increasing demand of quality of product. These all types of optimization techniques play important role in quality and productivity. In this paper show a review about both types of optimization techniques such as conventional and non-conventional optimization techniques. Many types of conventional optimization techniques are used for optimization of machine parameters included dynamic programming, goal programming, linear programming, sequential unconstrained minimization technique, simplex method etc. And the latest optimization techniques included Taguchi design, Response surface method (RSM), Fuzzy logic system (FLS), Genetic algorithm, Scatter search techniques, Partial Swarm optimization (PSO), Multi optimization genetic algorithm etc.

LabVIEW is system engineer software used to conduct required tests and measurements, control of hardware and data insights. Here, an MEM’s accelerometer (GY-61 ADXL335 3-axis accelerometer module) is used to capture the vibration signal, and an Ahuja professional performance electrets condenser omnidirectional characteristic microphone is used for capturing acoustic signal. The integrated circuit is designed with LabVIEW software, and all the analytical data are captured. This whole assembly is used to analyze as a “online tool wear monitoring system”. The required prototype model is capable of measuring, monitoring and capturing the data in both the normal and abnormal operating conditions. The physical parameters monitored and analyzed are as follows: voltage (V), RMS voltage, frequency, dB, etc.

In metal cutting process, the effectiveness of cost-quality-time matrix largely depends upon the optimum selection of cutting parameters. In present approach, Taguchi method and analysis of variance (ANOVA) is employed to develop a turning process model in terms of process parameters viz. cutting speed, feed rate and depth of cut for achieving the optimum surface finish .This process model is then verified experimentally by machining EN19 material. KeywordsTaguchi method, Speed, Feed, Depth of cut, CNC machine, Surface finish, EN19 material

Environmental friendly machining is one of the latest approach which is economical and also eco-friendly that improve the machinability. Different types of environmental friendly machining techniques are available e.g. MQL machining, cryogenic machining, dry machining and high pressure cooling approach. In this article, an attempt is made regarding environmental friendly machining processing, including different types of cutting fluids and machining techniques. The Knowledge of cutting fluid and its processing conditions is of critically importance to maximize the efficiency of cutting fluids in any machining process. In general, the generation of heat in the cutting zone due to friction at the tool-chip interface and the friction between the safety surface of the tool and the work piece is always the deciding...

Use of these hefty devices make this water dispenser heavy, bulky and consumes more power. Its compressor releases cfc which are very handy in ozone layer depletion. Our aim is to eliminate these limitations from the conventional water dispenser. We will create a potential difference using solar isolation to achieve the temperature difference.

To increase the accuracy capabilities of such machines, it is crucial to be able to study the geometric errors of the components and its effect on the quality of machined products. In five-axis machine tools, all linear axes are theoretically perpendicular (dot product, cos 90°= 0) to each other and directed along or around the X, Y and Z of the cartesian coordinate system; but in working machines, the axes are nearly perpendicular (cos89.90° 0) because of manufacturing error and assembly error or quasi-static error. The present paper discusses the development of a generalised error model for the effects of geometric errors of the components of the kinematic chain of a machine in the workspace and the results obtained by this model have been verified experimentally. The effect of geometric error has been studied further for cam profile generation using a five-axis machining centre and an improvement in the profile has been obtained.
