“…The process involves low cutting forces, so it is not affected by the workpiece length-to-diameter ratio and therefore it can turn long parts with small diameters [6]. Since employable abrasives could erode any materials, this process is ideally suitable for cutting materials with low machinability such as ceramics, composites, glass, and aerospace alloys [7][8][9]. Some attempts were previously made to study the AWJT process.…”

The effects of the main operational machining parameters on the material removal rate (MRR) in abrasive waterjet turning (AWJT) are presented in this paper using a statistical approach. The five most common machining parameters such as water pressure, abrasive mass flow rate, cutting head traverse speed, workpiece rotational speed, and depth of cut have been put into a five-level central composite rotatable experimental design (CCRD). The main effects of parameters and the interaction among them were analyzed by means of the analysis of variance (ANOVA) and the response surfaces for MRR were obtained fitting a second-order polynomial function. It has been found that depth of cut and cutting head traverse speed are the most influential parameters, whereas the rotational speed is insignificant. In addition, the investigations show that interactions between traverse speed and pressure, abrasive mass flow rate and depth of cut, and pressure and depth of cut are significant on MRR. This result advances the AWJT state of the art. A complete model discussion has been reported drawing interesting considerations on the AWJT process characterising phenomena, where parameters interactions play a fundamental role.

“…The authors emphasized the advantage of using a small nozzle diameter and a high fluid pressure to force the chip sideways and thus control the chip flow. Mazurkiewicz (2000) studied HPJA in steel cutting using high pressures up to 280 MPa via an external nozzle. By comparing the results to dry cutting and conventional cooling, it was proved that the jet assistance could reduce friction by inducing a sliding condition along the tool-chip interface, produce shorter chips, permit the use of higher cutting parameters, and nevertheless reduce the cutting forces.…”

“…In the shear process, the steel tube was fixtured into the cropping die, through the two phase fault tools before and after to shear, the power system of shearing machine was used to promote the main cutting tool move forward, and make the steel tube occur elastic-plastic deformation and rupture,while cement tube directly appear rigid brittle fracture under the action of shear force [2] , as shown in figure 1.…”

Abstract. It is because the matrix arrangement cement lining steel shear which have large elastic-plsatic deformation,yield deformation and slip body ,as well as existing multiple complex nonlinear and coupling that traditional methods have not been able to meet the analysis requirements. Therefore,The coupled theory based on elastic mechanics, fracture mechanics and brittle fracture was put forward by considering the change"elastic deformation-plastic yield-shear fracture",and having in-depth discussion about the sheear process.Eventually,a complete mathematical model of matrix arrangement cement lining steel shear has been formed to provides theoretical basis for shear performance and mechanics analysis.
