Abstract:
The car cover mold has characteristics of large structure size, complicated surface shape, dimensional precision, and high surface precision. The milling process of the splicing transition zone having different hardness can easily produce load mutation, which has an impact on the tool in the form of vibration. This vibration affects the surface topography of the splicing transition zone. In this article, we propose the surface motion model for ball-end milling cutter with impact vibration and the surface topography prediction model for splicing transition zone which is established based on the

During high speed milling hardened steel, the problem that tool vibration reducing machining surface quality causes led to a research for the influence characteristics of milled surface topography through high speed milling experiment. To determine the formation condition of milled surface topography, using displacement increment of origin of tool coordinate system which is caused by the milling cutter vibration and installation error, modifies the cutting motion trajectory.

Abstract:
Several manufacturing processes are used to beneficially influence the surface and subsurface properties of manufactured parts. Different aspects such as the surface topography or resulting residual stresses are addressed using different manufacturing processes. This paper presents the first approach for pulsed mechanical surface treatment (PMST), a new manufacturing process aiming to combine the mechanics used in deep rolling and shot or hammer peening. The process can generate a defined surface topography while constantly impinging a mechanical impact on the workpiece. Two different tools (t

Abstract:
Surface texture parameters are a quantitative way of characterising surface topographical features and are closely related to tribological properties. In this paper, the correlation between surface topographic features and friction coefficient is investigated on the basis of the proposed improved correlation analysis model for high-speed milling surface topography of hardened steel. It was found that the friction coefficient could not be accurately reflected by a single parameter, so a prediction model for the friction coefficient based on Sxp, Sq, Sp, Sz, Sku and Sdq was developed.

Abstract:
Tribological properties are determinant in the functionality of contacting surfaces of machine elements. The wear resistance or load bearing capacity influence the lifetime of these parts. In this study tribology-related surface topography parameters (Ssk, Sbi) and the hardness of hard turned surfaces are analyzed after hardness and topography measurements. Correlation coefficients were calculated for their relationships. It was found that the cutting parameters affect the wear resistance and the hardness in the opposite direction.

Abstract:
Micropitting is often observed on hardened materials that are involved with rolling/sliding contact. Even though micropitting is not a catastrophic failure, it may lead to excessive wear or macroscopic pitting. Field experiences and lab testing results have demonstrated that micropitting has a strong correlation to surface topography. Surface asperity contact induces elevated stresses that in turn cause near surface material distress. In this study a micropitting prediction model, based on the contact stresses of rough surfaces, is proposed. Surface topography is modified due to micropitting.

The tribological tests of hardened by nitriding c.p. titanium in pairs with 304L stainless steel showed lower friction coefficients in the period of rubbing, where the surface of the ti

Abstract A new process called in-mold metal spraying (IMMS) shows good potential for producing metallized plastic parts quickly and inexpensively. A zinc layer is deposited on mold cavity inserts using wire arc spraying and subsequently transferred to a plastic carrier via injection molding. Finely adjusted bonding strength between the carrier body and coating is essential for successful coating transfer. To that end, this study evaluates the influence of carrier body surface pretreatments on the transferability and bonding strength of zinc coating. Carrier bodies made of different types of st

The NC layers were characterized using optical and scanning electron microscopy and nanohardness measurements. 2D surface topography of the top surface was also carried out. The roughness of the peened surfaces depends on sample hardness. The hardened AISI 1075 martensitic steel had lower surface roughness valu

Abstract. Fine blanking is an economical process for manufacturing sheet metal workpieces with high sheared surface quality. When machining high-strength steels, material fatigue leads to increased punch wear, which reduces the economic efficiency of the process. This fatigue of the cutting edge and lateral punch surface can be counteracted by mechanical surface treatments. Deep rolling has proved particularly useful for such surface modification, as it allows both: machining of the lateral punch surface and the application of the cutting edge rounding required for fine blanking.

Abstract When rocks are fractured in tension, the fracture surfaces created are rough, with a wide range of surface morphologies possible. In previous studies of propped fracture conductivity using fractured samples, the fracture surface topography was found to have a strong influence on fracture conductivity and stimulation efficiency. Fracture surface patterns (relatively uniform, randomly rough, step changes, ridges and valleys) strongly affect propped fracture conductivity. Different types of surfaces can result in propped fracture conductivities differing by an order of magnitude or more

Microstructural phase transformations, commonly named as the white layer on hard turned components, have in recent times become an interesting research topic in machining. Three main theories have been proposed to justify the mechanisms of white layer formation: (i) rapid heating and quenching; (ii) severe plastic deformation; (iii) surface reaction with the environment. Furthermore, coolant application also affects the surface microstructural alterations resulting from machining operations, which have a significant influence on product performance and life.
