Tool Wear and Surface Evaluation in Drilling Fly Ash Geopolymer Using HSS, HSS-Co, and HSS-TiN Cutting Tools

Parallel analysis and MBI-HSS

Mr. Editor: It has been only recently possible to validate the Maslach Burnout Inventory-Human Services Survey (MBI-HSS) 1 among health professionals of Cali 2 , an important step for using this instrument with local empirical support in regard to its reliability of scoring and internal structure. However, two aspects of this analysis can be considered as methodological weaknesses. First, the C...

Optimization of cryogenic treatment parameters to maximise the tool wear of HSS tools by Taguchi method

This work describes the optimization of cryogenic treatment (CT) parameters such as the cooling rate, the soaking temperature, the soaking time, the tempering temperature and the tempering time to maximise the tool wear of high speed steel tools in dry turning of AISI 316 grade austenitic stainless steels by Taguchi method. For this purpose, four iteration of Taguchi design (L16) have been used...

Enhancement Wear Properties of HSS-M2 Tool Steel with WC Deposited by SMAW Process

In this study, the effect of cladded tungsten carbide layer upon HSS - M2 tool steel on microstructure, hardness, and wear behavior has been studied in two cases without using the middle layer and using the middle layer of nickel. Tungsten Carbide cladded on HSS - M2 tool steel by Arc Weld ( SMAW ). The ASTM-G65 wear test was used to determine its application for use in the mineral indus...

A robust inner-outer HSS preconditioner

This paper presents an inner-outer preconditioner for symmetric positive definite matrices based on hierarchically semiseparable (HSS) matrix representation. A sequence of new HSS algorithms are developed, including some ULV-type HSS methods and triangular HSS methods. During the construction of this preconditioner, off-diagonal blocks are compressed in parallel, and an approximate HSS form is ...
