The Effect of Holding Time of Deep Cryogenic-Treated AISI D3 Cutting Tool on Machinability of Low Carbon Steels Using Taguchi’s Technique

This paper deals with the effect of machining parameters on tool wear, surface roughness and cutting forces in dry turning of low carbon steel with deep cryo-treated AISI D3 tool steel. AISI D3 tool steel was used for preparation of cutting tools as per International Standard Organization (ISO: 3685-1993). Deep cryogenic treatment ([Formula: see text]C) of D3 tool steel was carried out at different holding time (12[Formula: see text]h, 24[Formula: see text]h and 36[Formula: see text]h) followed by tempering at [Formula: see text]C for 2[Formula: see text]h. Taguchi’s L27 orthogonal array is used for optimizing the process parameters during machining process. Analysis of variance (ANOVA) was carried out to study the significance of the input parameters. Mathematical models were developed using linear regression analysis for validating results. The tool worn surface shows the abrasion wear and oxidation wear were the main wear mechanisms observed under higher speed and feed rate cutting conditions.

INDUSTEEL D2

Industeel D2 is an air-hardening, high-carbon (1.5%), high-chromium (12%), alloy cold-work tool steel that also contains molybdenum and vanadium. It is specifically designed to provide high abrasive wear resistance and high hardenability. This grade can be used for cutting and deformation tools submitted to high abrasive wear. It can be used when Type D3 tool steel shows an excessive sensitivity to cracking or chipping. This datasheet provides information on composition, physical properties, hardness, and elasticity. Filing Code: TS-791. Producer or source: Industeel France (a subsidiary of ArcelorMittal.

Optimization of Friction Surfacing Process Parameters on Low Carbon Steel Using Taguchi Approach

Friction surfacing is a solid-state coating technique process in which a mechtrode is rotated against the substrate under pressure, henceforth forming a coat on the substrate. This process not only can be used as coating process but it also provides flexibility in coating different materials as a revamp manufacturing process and it is suitable for getting excellent mechanical properties after the surfaced deposits. Bond strength is very good and these deposits are expected to serve better service life. The present work deals with mechtrode of SS-316, D3-tool steel and aa-2014 are coated on low carbon steel substrate by friction surfacing process and design of experiment were done by using taguchi L9 orthogonal array where the process parameters are mechtrode, rotational speed and traverse speed. The coating thickness, coating width and the SEM-microstructure analysis were studied.
