The leveling process is the initial stage before operating a lathe. test will be carried out if flatness on machine and results have deviated greatly, it must leveled This study aims at high level of accuracy tools in form three types Gedee Weiler LZ 330 G lathes located AK-Manufaktur Bantaeng Manufacturing Workshop. type research categorized as quantitative which an inductive, objective scient...

Developing technology and production needs are increasing the need for machinery metal sector. On lathe machine, is one of most widely used machines in sector, work accidents serious occupational diseases occur every year. In order to prevent this, it has become a necessity create an safety culture general. existing hazards possible small large enterprises necessary identify them first make eff...

Article history: Received 6 October, 2015 Accepted 7 March 2016 Available online 8 March 2016 Dry friction depends on the surface topography which, in turn, is governed by machining parameters in addition to several other factors,. Therefore, in order to establish a qualitative relationship among these factors, the surface roughness and coefficient of static friction are measured for specimens ...

In this paper, we dscribe the measurement of brain activity during lathe operation in a VR lathe environment by near-infrared spectroscopy. The results show that the trials with sounds of processing, oxyHb tended to increase in the auditory area during lathe operation. On the other hand, oxyHb didn't change in in the auditory area. The results also show that oxyHb tended to increase in in the f...

Tool positioning and its error optimization are gaining considerable importance in engineering applications. A number of machine vision systems have been developed for tool wear and conditioning assessment. A machine vision system for lathe tool position and verification was developed. To evaluate the performance of developed system, images of lathe tool were captured before and after the tool ...

The challenge of current manufacturing industries is increase production rate in order to maintain their competitiveness in market.This paper investigates the effect of spindle speed and feed on material removal rate in turning operation execute on conventional lathe machine. An effort has been made to model the one response variable using Taguchi and ANOVA method. Taguchi L9 orthogonal array i...

In the turning operation the relative dynamic motion between cutting tool and workpiece, or vibration is a frequent problem, which affects the result of the machining, in particular the surface finish. The tool life is also influenced by the vibrations. When the working environment is considered, noise is frequently introduced by dynamic motion between the cutting tool and the workpiece. By pro...

Since its first description in 1936, siderosis of lung has been considered a benign pneumoconiosis due to absence of significant clinical symptoms or respiratory impairment. Subsequently, authors have questioned the non-fibrogenic property of iron. However, siderosis causing interstitial lung disease with usual interstitial pneumonia (UIP) pattern has not been described in the past. We report a...
