Effects of natural rock properties on cutting forces, specific energy and specific cutting energy by four-axis machine [PDF]
Arabian Journal of Geosciences, 2018 This study used a four-axis machine to investigate the processability of natural rocks and parameters affecting cutting forces (Cf), specific energy (Se) and specific cutting energy (Sc). A total of 12 types of natural rocks (7 marbles, 3 travertines, and 2 limestones) were categorized according to their geological formations and subjected to various ...

Force and specific energy in stone cutting by diamond mill
International Journal of Machine Tools and Manufacture, 2004Cutting force and energy are often used as parameters for monitoring the stone cutting process. Empirical models are required to guide the selection of cutting conditions. In this paper, the effect of cutting conditions on cutting force and energy are reviewed.

A study on the energy efficiency of specific cutting energy in laser-assisted machining
Applied Thermal Engineering, 2016Abstract As hybrid machining approach, laser assisted machining (LAM) is a processing method used to improve productivity and surface quality, in which the workpiece is softened by laser preheating. LAM is also an effective method to save cutting energy by reducing cutting forces.

Abstract Single polycrystalline diamond compact (PDC) cutting is a practical technique to understand the rockâtool interactions in drag-bit-type geothermal drilling operations. This paper introduces a rotary cutting method to determine specific cutting energy (SCE) and compares it with the conventional linear cutting method. In this work,

Effects of Rock Properties on Specific Cutting Energy in Linear Cutting of Sandstones by Picks
Rock Mechanics and Rock Engineering, 2005Specific cutting energy (SE) has been widely used to assess the rock cuttability for mechanical excavation purposes. Some prediction models were developed for SE through correlating rock properties with SE values. However, some of the textural and compositional rock parameters i.e.

Influence of cutting parameters on cutting specific energy of Inconel718 based on strain gradient
Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2023In this paper, the Johnson-Cook constitutive model is modified by considering the influence of hard point such as TiC and NbC in the matrix of Inconel718 on the deformation stress. The theoretical model of cutting specific energy in the main deformation zone of Inconel718 is modified based on the new constitutive model by combining the strain gradient ...

Investigation on size effect of specific cutting energy in mechanical micro-cutting
The International Journal of Advanced Manufacturing Technology, 2017Mechanical micro-cutting is one of advanced processes to manufacture the miniature parts. The uncut chip thickness is one of the two important parameters in mechanical cutting. The uncut chip thickness and the cutting edge radius are at the same length scale, and the cutting tool extrudes and shears the workpiece with the round cutting edge during ...
