Acoustic identification of rocks during drilling process
Drilling into a rock massif is energetically extremely consumptive process. Hence the optimization of drilling regime with objective of energy consumption minimization, is very important. Proposed article discusses partial problem of this problem. During the drilling process it is useful to know the drilled rock type, whereas to particular drilled rock needs convenient drilling regime, which is...
متن کاملOptimization on Delamination of Cutting Parameter during Drilling on Gfrp Plastics Based on Taguchi Method
Drilling of glass fibre reinforced plastic (GFRP) composite is different from metallic materials due to its mechanical properties. The drilling of this material may generate delamination of drilled holes on workpiece. The purpose of this paper is to investigate the influence of the cutting parameters, such as cutting speed and feed rate, point angle of drill and material thickness on delaminati...

متن کاملStudies on the Formation of Discontinues Rock Fragments during Drilling and Cutting Operation
* Corresponding author – [email protected] Tel: 414-229-4126 Fax:414-229-6958 ABSTRACT Understanding the fundamental tribology associated with the cutting of rock under extremely high pressure and high temperature (HPHT) conditions are extremely important in mining and drilling operations. In this paper, a rock fragmentation process is simulated during mechanical cutting of rock using an explicit...
متن کاملChip Formation Process using Finite Element Simulation “Influence of Cutting Speed Variation”
The main aim of this paper is to study the material removal phenomenon using the finite element method (FEM) analysis for orthogonal cutting, and the impact of cutting speed variation on the chip formation, stress and plastic deformation. We have explored different constitutive models describing the tool-workpiece interaction. The Johnson-Cook constitutive model with damage initiation and damag...
