Surface roughness is used to determine and evaluate the quality of a final product in turned parts. In order to get better surface finish, the proper setting of cutting parameters is crucial before the process takes place. Titanium Grade 5 material is one whose surface hardness is high and it is used for making Aerospace engine components, titanium rod and ideal materials for medical implements...

This paper presents a comprehensive ANN based multisensor fusion approach designed to support the implementation of an adaptive error compensation of geometric, thermal and dynamic errors for enhancing the accuracy of CNC machine tools. Accurate and efficient model to perform on-line error prediction is an essential part of the compensation process. The proposed approach consists of the followi...

In this research paper, E 250 B0 as per IS: 2062 steel material are turned on computer numeric controlled (CNC) turning center by using Chemical Vapor Deposition (CVD) coated cemented carbide inserts of 0.8 mm and 1.2 mm. This paper discusses an investigation of effect of process parameters (speed, feed, depth of cut & nose radius) on responding quality parameter (boring operation). This study ...

A knowledge-based process-planning system for generating workplans for idealized lathe CNC machines is discussed. It transforms CAD-like diagrams of rotational-symmetric workpieces into abstract NC programs. To simplify development and evolution , declarative representations are used for all processing stages and steps, including a qualitative simulation of lathe turning. The version presented ...

The focus of this study is to examine the effect of cellulose nanocrystals (CNC) on the properties of polylactic acid (PLA) films. The films are fabricated via melt compounding and melt fiber spinning followed by compression molding. Film fracture morphology, thermal properties, crystallization behavior, thermo-mechanical behavior, and mechanical behavior were determined as a function of CNC co...

Article history: Received January 2, 2015 Received in revised format 6 February 2015 Accepted 15 February 2015 Available online February 17 2015 Surface roughness and cutting forces are considered as important factors to determine machinability rate and the quality of product. A number of factors like cutting speed, feed rate, depth of cutting and tool noise radius influence the surface roughne...

Energy demand modeling of machining processes is the foundation of energy optimization. Energy demand of machining state transition is integral to the energy requirements of the machining process. However, research focus on energy modeling of state transition is scarce. To fill this gap, an energy demand modeling methodology of key state transitions of the turning process is proposed. The estab...

Cellulose nanocrystals (CNCs), a class of renewable bionanomaterials with excellent mechanical properties, have gained major interest as filler for polymers. However, challenges associated with effective CNC dispersion have hindered the production of composites with desired property enhancements. Here, composites of polypropylene (PP) and low density polyethylene (LDPE) with 5e10 wt% unmodified...
