These articles have been peer-reviewed and accepted for publication in IJAT, but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

  • Effect of small quantity lubrication on grindability of hardened AISI 4340 steel   Order a copy of this article
    by Sirsendu Mahata, Joydip Roy, Ankesh Samanta, Bijoy Mandal, Santanu Das 
    Abstract: The process of grinding is normally associated with generation of considerable amount of heat. To reduce thermal damages, grinding zone is often flooded with liquid coolant, most of which is wasted and may cause severe environmental pollution. In the present work, grindability of hardened AISI 4340 steel is assessed at various infeeds, using an eco-friendly vegetable oil applied by small quantity lubrication (SQL) technique, so as to reduce the quantity of coolant. At the same infeed, grinding is also performed by applying a uniform layer of semi-solid lubricant (grease) on the work surface. Comparison is made between the two methods in terms of force, surface roughness, specific grinding energy and observed chip forms. Results prove that SQL technique using vegetable oil is better than grease as a lubricant in terms of force requirement, while surface quality shows improvement with grease layer lapped on the work surface than with SQL technique.
    Keywords: grinding; grindability; cooling; lubrication; SQL; roughness; force; eco-friendly manufacturing.

  • Development of cBN electroplated end-mill combined cutting and grinding for precision machining of CFRP   Order a copy of this article
    by Tatsuya Furuki, Yugo Kabaya, Toshiki Hirogaki, Eiichi Aoyama, Kiyofumi Inaba, Kazuna Fujiwara 
    Abstract: Carbon-fibre reinforced plastic (CFRP) has been applied to various fields because of its excellent mechanical properties. Generally, after fabrication with moulding, CFRP requires additional machining, such as cutting or grinding. As the cutting tool for CFRP, a diamond-coated end-mill with high wear resistance has been developed. However, burr or uncut fibre is easily formed. Meanwhile, in the case when a grinding wheel is used, the machining efficiency is low even though there are sharp edges with burr or uncut fibres. Therefore, there is a need for the development of a versatile tool that can achieve precision machining of CFRP with high efficiency. This study develops a cBN electroplated end-mill that is a combination of a cutting tool and a grinding wheel. This report shows that the developed tool is able to perform high-efficiency cutting like the diamond coated end-mill, and high-precision grinding like a diamond wheel.
    Keywords: CFRP; cBN; electroplated end-milling; grinding; machining centre.

  • Study on the segmentation of abrasive grains in diamond tools   Order a copy of this article
    by Yanfen Lin, Congfu Fang 
    Abstract: Segmentation of abrasive images of diamond tools is the most important part of computer vision, which is the basis for detecting the state of diamond tools, such as the characteristics of diamond number, distribution, size and state. As diamond images have rich irregular background textures and reflective features, it is a major challenge to detect and segment these diamond images. The present work demonstrates an invalid edge elimination method for such images to segment and mat the diamond grains, which mainly consists of histogram, edge detection, and morphology. Based on the method, the part of diamond in the original images can be accurately and effectively segmented and matted. Then, the method is also used to segment and mat the diamond grains in other images of different diamond tools, and it also has a good segmenting and matting effect. Finally, the segmented and extracted diamond grains are used to analyse the diamond number, density and its wear state, the result indicates that the proposed method can be used in diamond tool detection.
    Keywords: diamond tool; topography; abrasive grain; segmentation; matting.
