Abstract: Risk management has been acknowledged as an area of concern in the management of construction project risks. One of the critical phases of the risk management process is risk identification, for if risks are not identified, they can have an adverse impact on the successful completion of projects. There appears to be little evidence of studies highlighting the correlation between project risk identification and project performance in South Africa construction industry, especially among small and medium contractors. Therefore, the current study aims to investigate the extent to which project risk identification leads to project performance of SMEs construction project in Gauteng, South Africa. Data were collected through a questionnaire survey among SMEs who were conveniently sampled in Gauteng. Descriptive and inferential statistics were used to analyze data collect. Findings revealed that there is a positive significant relationship between project risk identification and project perfo

Abstract: Grinding is usually the last finishing operation to be completed on the work piece and hence any deviations in quality such as geometrical errors and surface finish cannot be passed onto the next operation. Grinding is classified as a machining process that removes material from the work piece using similar principles to that of milling or turning. However, instead of having the one large cutting edge, there are numerous small cutting edges by way of grits on the grinding wheel surface, with all of them working together at extremely high speeds. One of the main problems in grinding is the growing vibration (Chatter) between wheel and work piece during the process. Many studies and tests have been made in order to detect and avoid this dynamic phenomenon which affects a number of parameters including wheel wear and work piece quality. However, a possible method to prevent this type of chatter is to apply a periodic disengagement of the wheel from the work piece and periodic variation of
