The fiber laser concept is proven technology for telecom applications where its single mode performance and reliability is essential. Newer generation diode-pumped fiber lasers are using pump diodes especially developed for telecom applications and therefore offer excellent controllability of the laser pulse length and pulse frequency. In recent years the output power of fiber lasers has increa...

In this study, a model of micro-milling cutting forces based on elementary experiments is developed. Elementary tests were used to identify the parameters new that includes uncut chip thickness and effect edge radius. This assumes straight rigid tool divided into two terms represent ploughing shearing regimes. The complex shape micro-end-mill decomposed linear edges which force can be applied. ...

Magnesium based metal matrix composite (Mg/MMC) has been widely used in various area such as aerospace and automobile due to its light weight and better mechanical properties. However the heterogeneous structure and high abrasiveness particles make it to become a difficult-to-cut material especially in micro scale machining, several critical issues in machining process become prominent with the...

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...

Reliable prediction of cutting forces is essential for micromilling. In this paper, a fuzzy cutting force modelling method based on subtractive clustering method filters the noise and estimates the instantaneous cutting forces using observations acquired by sensors during cutting experiments. In the experimental case study, four data sets of micromilling cutting force are used. Each data set is...

Tool wear, minimum chip thickness and micro tool geometry are found to have a significant influence on the surface roughness through experimental analysis of the micro-end-milling process. To address these issues, a surface roughness model is developed and validated in this present work. Firstly, experimental analysis for the tool wear and surface roughness was performed based on the micro-end-...

In this study, 3-D finite element modeling of precision hard turning has been used to investigate the effects of cutting edge microgeometry on tool forces, temperatures and stresses in machining of AISI H13 steel using polycrystalline cubic boron nitrite (PCBN) inserts with two distinct edge preparations. Hard turning experiments were conducted to investigate the effects of cutting edge geometr...

This paper presents the development of a cutting force model for end milling process under various cutting conditions and the tool wear is measured by Scanning Electron Microscope (SEM).This novel approach combines the concept of experimental design and finite element modeling of the cutting process which allows for a fairly accurate prediction of cutting forces with a significantly lower compu...
