The demand for measuring equipments of automatic optical inspection has grown rapidly, because of its benefits of promoted efficiency and higher precision. Instead of manual projection measurements, measurement performance and efficiency can be obviously enhanced by the image measurement system. In this investigation, digital image processing and geometrical measurement principles have been int...

The overall goal of the research is the integration of geometric and mechanistic models for cutting process simulation and feedrate optimization. Five-axis milling methods are used in industries such as aerospace, automotive and mold for free-form surface machining. In these process, surface quality and material removal rate are of very important. Conservative cutting parameters have been mostl...

The ultimate ambition of a robotic system in surgical theater has to be the safety of the involved humans means: patient, physicians, nurses. In order to provide that claim the criteria of ergonomics, redundancy, short reaction time, and accuracy must be met. In contrast to many other surgical robotic applications we are studying complex bone cut trajectories which require several distinct orie...

Conventional tool-path generation strategies are readily available to generate geometrically feasible trajectories. Such approaches seldom take into consideration physical process concerns or dynamic system limitations. In the present work, an approach for improving a geometrically feasible tool-path trajectory based on quantifiable process metrics is developed. Two specific measures of toolpat...

Laguerre geometry provides a simple approach to the design of rational curves and surfaces with rational offsets. These so-called PH curves and PN surfaces can be constructed from arbitrary rational curves or surfaces with help of a geometric transformation which describes a change between two models of Laguerre geometry. Closely related to that is their optical interpretation as anticaustics o...

Enzymatic saccharification (Hydrolysis) is one of the technologies to hydrolyze lignocellulosic biomass. In this study, Bangladeshi bagasse is used as feedstock for enzymatic saccharification and ethanol fermentation. Cutter mill and Mechano-chemical treatment (Ball mill) are used for pretreatment. The main objective of this study is to investigate the effect of substrate concentration, pretrea...

Machining of thin-walled (aluminium alloy) aerospace structures is a critical process due to the high warpage. Current practices in the fixture design and the choice of cutting parameters rely solely on conservative guidelines and the designer’s experience. This paper presents evaluation of clamping force to fix the work piecein aVacuum fixture using Vacuum pump. The ISCARonline calculator is u...

This chapter covers the various free-form surface flank milling strategies available, focusing in particular on those for ruled surfaces as widely used in defining turbomachine parts. All these positionings seek to reduce interference between the cutting tool and the surface to be milled so as to respect the tolerances dictated by the Design Office. The range of strategies presented goes from t...

Helical milling with the advantages of stable machining process, a well-machined surface quality, etc., is an interest researchers and producers. Machined roughness (arithmetic mean deviation (Ra) maximum height assessed profile (Rz)) power consumption as two main characteristic parameters were studied chosen response factors to evaluate machinability Scots pine helical milling. Input variables...
