Evaluation of machine-tool motion accuracy using a CNC machining centre in micro-milling processes
The demand for micro holes, micro-moulds and micro forms continues to grow as high-tech industries demand miniaturized products. Sectors such as aerospace, microelectronics, medicine, and even the automotive sector, are just some examples of enterprises that are taking advantage of micro-manufacturing technologies. Within this framework, the need to adapt the knowledge of macro-scale manufactur...
متن کاملModeling micro - end - milling operations . Part II : tool run - out
The effect of run-out is clearly noticed in micro-end-milling operations, while the same run-out creates negligible change at the cutting force profile of conventional end-milling operations. In this paper, the cutting force characteristics of micro-end-milling operations with tool run-out are investigated. An analytical cutting force model is developed for micro-end-milling operations with too...

متن کاملOptimization of Machining Parameters to Minimize Tool Deflection in the End Milling Operation Using Genetic Algorithm
Optimization of cutting parameters is valuable in terms of providing high precision and efficient machining. One of the effects of cutting force in the end milling operation with low diameter tool (during metal cutting) is tool deflection. Assuming that machining errors mostly arise from tool deflection, attempt was made to optimize machining parameters using Genetic Algorithm (GA) so as to min...
متن کاملPrediction of Tool Wear from Machining Parameters by Response Surface Methodology in End Milling
Tool wear increases cutting force, vibration, temperature, etc in end milling and reduces surface finish of the machined work piece. Mathematical model has been developed to predict the tool wear in terms of machining parameters such as helix angle of cutting tool, spindle speed, feed rate, axial and radial depth of cut. Central composite rotatable second order response surface methodology was ...
