The present study investigates the optimization of multiple responses in turning of EN-8 steel by the Taguchi and grey relational analysis. The performance characteristics considered are tangential force, feed force and radial force. Grey relational theory is adopted to determine the best process parameters that give lower magnitude of tangential, feed, radial forces and optimal cutting parameters. An orthogonal array L18 is used for the experimental design. The setting of process parameters— nose radius, 0.8mm; cutting speed, 60.65 m/min; feed rate, 0.04 mm/rev; and depth of cut, 0.60 mm— has

Tangential turning, a precision high-speed finishing procedure, is crucial for achieving superior surface quality and dimensional accuracy in cylindrical workpieces. This advanced machining technique leverages tangentially applied cutting forces to minimize tool deflection and vibration, thereby enhancing the surface integrity of the final product. Despite its advantages, tangential turning poses challenges in maintaining cylindrical accuracy, necessitating a thorough investigation of cylindrical error. Cylindrical error, the deviation of the machined surface from a perfect cylinder, significa

This research aims to develop the mathematical model and propose a method for estimating the feed stochasticity impact on the tangential cutting force during turning. The main reason for this research is that the existing models for determining the tangential component of the cutting force do not take into account the stochasticity of the feed rate. Measurements of tangential cutting force during turning on general-purpose lathes with known feed dispersion parameters were made. The mathematical model was developed, and dispersion characteristics (mean value, dispersion and mean square deviatio

A main topic in mass production of machine parts is how to increase the productivity to produce more parts in a given time while maintaining the prescribed surface quality on the machined surfaces. Novel machining procedures have been introduced to achieve this goal; however, the further development of already established and wide-spread procedures can offer simply accessible solutions. Tangential turning is a rediscovered variant of the traditional turning procedure, where a specially designed cutting tool ensures chip removal with a feed tangential to the workpiece.

The aim was to develop, manufacture and test a technically simple dynamometer for monitoring the cutting process during boring and turning. An S20R-SSSCR09 right-hand cutter was selected as a research object. To register the cutting force and vibration movements of the cutter tip in tangential and radial directions, the cutter was equipped with four KF5P1-10-400-A-12 strain gauges mounted according to a half-bridge scheme. The bending stiffness of the cutter in two directions was measured by a DOU-3-01 compression dynamometer and a DDP-10A dial indicator. The cutter natural frequency was deter

The influence of the traverse speed, the rotational speed, and the relative position of the jet to the specimen (lateral jet shift) were investigated. Based on the previous research done in this field, the multi-pass tangential turning method was selected. Rotational speed does not seem to have a significant impact on the AWJ turning process.

This study investigates the cutting force distribution during tangential turning of 42CrMo4 alloy steel under high cutting speeds and high feed rates. The experiments were conducted by varying cutting speed (200 and 250 m/min), feed rate (0.3 and 0.8 mm/rev), and depth of cut (0.1 and 0.2 mm). The major cutting force, feed directional force, and thrust force components were measured, and their maximum values and relative ratios were analysed. The results indicate that both cutting speed and feed rate have a significant influence on the magnitude and distribution of the cutting force components

Abstract. The increase of machining efficiency is a main goal and a complex task for the production engineering in the industrial environment, while the prescribed surface quality must be maintained. The tangential turning procedure offers a solution while achieving high feeds (thus lowering the machining time), where the roughness of the machined surface can reach its required low value. In this study, several parameters of the roughness profile are analyzed on tangentially machined surfaces. The experimental setups are planned and carried out following the method of Design of Experiments. Th

Abstract A simulation model that considers the radial and tangential vibrations and their abatement using active actuators in a turning process is developed. The model is simulated using Simulink in Matlab environment to assess the possibility of using an active actuator to reduce vibrations in two directions. Comparison is made between the two orthogonal actuators scenario and the one inclined actuator scenario. The results indicate that vibrations reduction using an active inclined actuator is comparable to that of two orthogonal ones.

Finite element method (FEM) has been qualified as an excellent method to analyze machining processes. Many researchers commonly adopt an orthogonal FE model to simulate hard turning process without considering the effect of tool nose radius and/or lead angle. However, the PCBN cutting tools usually possess a nose radius of 0.4mm to 0.8mm, which equals to the magnitude of cutting depth/feed in hard turning. To explore the effect of tool nose radius and rake angle on hard turning AISI 52100 steel process, an explicit dynamic thermo-mechanical three-dimensional (3D) FEM is developed. The model co

Abstract. The authors present a method for determining cutting forces during orthogonal turning of C45 steel. The method utilizes Oxley’s chip formation model as well as Johnson-Cook (J-C) constitutive equation and is based on the assumption that the tool is perfectly sharp and the chip formation process is continuous. It is also assumed that the heat exchange between the workpiece, the tool and the chip is carried out by conduction with negligibly small loses caused by convection and radiation and that the thickness of the chip contacting the rake face is constant.

Compared with grinding, hard turning is a competitive manufacturing process that in many cases has substantial benefits. The most significant difference between hard turning and grinding is that hard turning may induce a relatively deep compressive residual stress. However, the interactions among the residual stress profile, applied load, and surface material, and their effects on component life in rolling contact are poorly understood. Further, contact stresses and strains are difficult to measure using the current experimental techniques due to the small-scale of the phenomena. A new simulat

Abstract The future capital intensive manufacturing industry will demand efficient utilization of machine tools. Thus, a modular real-time adaptive control (AC) system for turning is being developed. Different real-time monitoring and control tasks are assigned to integral subsystems respectively, organized in a distributed computer system and supervised by a master computer in accordance with a main AC strategy. The subsystem for quasi-static cutting force control adapts the feedrate to the present machining situation in order to keep the tangential cutting force constant at a maximum level,

This paper deals with the modeling and analysis of the cutting tool’s global dynamics in the orthogonal cutting process of turning operations considering the effect of state dependency and fly-over in one model. In particular, the one-degree-of-freedom non-smooth model, presented by Wahi and Chatterjee in 2008, is extended by the consideration of vibrations in the direction perpendicular to the feed velocity. This results in the state-dependency of the model and gives an additional direction in which fly-over can occur. The constructed mathematical model consists of a nonlinear PDE, which desc

In order to increase the performance of a modern gas turbine, compressors are required to provide higher pressure ratio and avoid incurring higher losses. The tandem aerofoil has the potential to achieve a higher blade loading in combination with lower losses compared to single vanes. The main reason for this is due to the fact that a new boundary layer is generated on the second blade surface and the turning can be achieved with smaller separation occurring. The lift split between the two vanes with respect to the overall turning is an important design choice. In this paper an automated three
