the machine to be designed and developed with a view to resolve one ofthe irksome problems of this institute has been facing every year. this institute issurrounded by vast non- fertile land area of about 200 acres, which becomes widelyoccupied by numerous breads of bushes and shrubs during post-rainy season. due tothis unwanted proliferation of such verdant institute gets abysmal look and that...

Rather than upgrading a software system to the next version by installing a new binary, software systems could be updated “on-thefly” during their execution. We are developing a software evolution system that leverages aspect technology. As changes typically spread across several classes, we can handle updates like other crosscutting concerns: we encapsulate all changes, constituting a logical ...

The paper describes the design and implementation of a cutting fluid monitoring system, as well development an algorithm to increase life in machine tool reservoir. Cutting fluids are most common type coolant machining. During its use, it becomes contaminated gradually degrades until needs be replaced with fresh fluid. To effective service life, parameters should monitored at regular intervals,...

Several tasks that autonomous service robots will be expected to do involve changing material objects by cutting or separating parts, then rearranging them to obtain assemblages satisfying certain properties. In this paper we describe a system to represent and reason about entities that disappear or are created by the robot through such actions. Entities are grounded in objects that the robot c...

Abstract. Tool wear sensing plays an important role in the optimisation of tool exchange and tip geometry compensation during automated machining in flexible manufacturing system. The focus of this work is to develop a reliable method to estimate flank wear during end milling process. A neural-fuzzy scheme is applied to perform one-step-ahead prediction of flank wear from cutting force signals ...

* Corresponding author.e-mail: [email protected] Abstract In machining as a result of the cutting motion, the surface of workpiece will be influenced by cutting parameters, cutting force and vibrations etc. But the effects of vibrations have been paid less attention. Thus, by monitoring the machined surface topography of the workpiece and extracting the relevant information the cutting proce...

One of the big challenges in machining is replacing the cutting tool at the right time. Carrying on the process with a dull tool may degrade the product quality. However, it may be unnecessary to change the cutting tool if it is still capable of continuing the cutting operation. Both of these cases could increase the production cost. Therefore, an effective tool conditionmonitoring systemmay re...

Based on the dangers of suspended oil mist microparticles from machining to the environment and health of worker. A theoretical analysis on the generation mechanism of cutting fluid oil mist and an experimental study on its influencing factors were carried out in this paper. The experiment was conducted in closed lathe with flood cutting fluid feed system. A droplet diameter measuring system wa...
