The cutting process was conducted using carbide coated ball nose milling inserts and liquid nitrogen as the coolant. A full factorial with three factors two levels each was adopted to run the experiments. Results revealed that the surface roughness were in the range of 0.134 μm to 0.264 μm which were less than the values obtained using manual polishing process (≈0.5 μm). The roughness was significantly affected by the interaction between cutting speed and feed rate followed by the radial depth of cut. Microstructure beneath the machined surface exhibited some plastic deformation down to 30.93 μm due to the sliding of tool over the surface during the shearing process that increased the cutting pressure at elevated temperature and caused deformation of the grain structure, which was better than dry machining.","PeriodicalId":35407,"journal":{"name":"Progress in Industrial Ecology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/PIE.2018.097061","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46521723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The recycled polymer blend is sourced from rejected-unused disposable diapers containing polypropylene and polyethylene (r-PP/PE). The kenaf flour fibre is compounded with r-PP/PE by using internal mixer machine with five variations of fibre loading which are 0, 30, 40, 50, and 60 wt.%. The water immersion test is conducted by immersing the samples in the distilled water for 24 hours as well as samples for tensile, flexural, and Izod impact tests. Experimental results show some improvement on some properties (impact strength) as well as degradation in other mechanical properties.

The use of cryogenic machining could improve the functional performance of machined parts, through engineered surface integrity. The state of the art of cryogenic machining, benefits, and applications have been reviewed first. It is obvious that cryogenic research to date has focused on the hard-to-cut materials such as titanium, Inconel 718 and AISI 52100 but few studies were carried out on hardened steel. The overall objective of this review is to advance the state of art of cryogenic machining in terms of machinability and thus complement available limited literature. Cryogenic machining can increase machinability, in terms of its effects on tool life, cutting force, chip formation, and surface integrity. In conclusion, cryogenic application in manufacturing processes could possibly be used as an enhancement method for surface hardening when using appropriate cutting conditions, thus avoiding expensive and time-consuming post-treatment processes.","PeriodicalId":35407,"journal":{"name":"Progress in Industrial Ecology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1504/PIE.2018.097065","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48149030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The modelling set a constant weld current of 12.2 kA as the wave input with a frequency of 50 Hz. ANSYS 12.0 was used to complete the FEM with the discretisation from the resemblance energy. The result of the modelling showed that the highest temperature was always attained at the end of the weld time.

The cycle efficiency has improved by 2% with the incorporation of an auxiliary superheater in the system.
