Progressive Technology Diagnostics and Factors Affecting Machinability

Abstract

The Water as an element with its force is applied to the solid substances and thus violates their. A man started to notice the power of water and gradually it began to exploit to their advantage and developed technology of machining of various materials, which brought a facility generating pressure water jet. [1] Presently cutting materials technology is an essential technology pre-production stages. Article discusses the production system with technology of abrasive water jet and is aimed at assessing the impact of selected factors of the technological process in the dividing of materials using this technology. The main part describes the influence of factors on the depth of cut and surface topography of machined in terms of roughness. At the end of the article are evaluated selected technological factors used in cutting of materials.

Prediction of the Geometrical Accuracy of the Machined Surface of the Tool Steel EN X30WCrV9-3 after Electrical Discharge Machining with CuZn37 Wire Electrode

“…Wrong guiding of the wire electrode may cause excessive vibrations [41] or deformations that undoubtedly will be reflected on the final quality of the machined surface [42]. This adverse effect can be, to a certain extent, eliminated by the optimal tension of the wire electrode (Figure 2).…”

Application of Simulation for Product Quality Enhancement

“…Its influence may result in various deformations and surface defects. [7] Problem Definition When designing a plastic component, it is quite difficult to design the product so that the same wall thickness is maintained at all points, especially when it comes to a mould where ribs are necessary to 0-1 volume filling of the mould cavity by the melt 1-2 compression of the melt 2-3 holding pressure 3-4 isochoric transition at T1bar 4-5 cooling without pressure 5-6 cooling off the form A the total volume shrinkage SV B production volume shrinkage SVV TVY temperature of ejection from the mould form T0 temperature of environment maintain a higher strength or if seal groove are necessary. In such cases, the designer has limited possibilities of designing the shape of the product being produced, because he must also consider the technological aspects of production.…”

Quality and Productivity Enhancement at the Machining of Wear Resistant Hard Coats

“…Molten or semi-molten materials are sprayed onto the surface by means of the high temperature, high velocity gas stream, producing a dense spray coating which can be ground to a very high surface finish. [3,4,5] The principle of HCOF spraying technology is shown in Figure 1. [6] The utilisation of the HVOF coating technique allows the application of coating materials such as metals, alloys and ceramics to produce a coating of exceptional hardness, outstanding adhesion to the substrate material.…”
