surface roughnessturning40Х steelmetal buildupadhesionsimulationIn the machining of steel, metal from the workpiece may build up on the tool's cutting edge. The influence of such buildup on the roughness of the machined surface in the turning of 40啸 steel is simulated. The cutting conditions...
Surface roughness of steel sheets (St. 37 H2) was changed using sandpaper with different grades. One group of specimens was kept unpolished as reference samples and for the other groups the surface roughness was measured with a profilometer system in conjunction with a surface roughness program ...
The roughness effect on the frequency of frictional sound Dry sliding of two bodies in contact generates a wide range of effects like friction, wear, heat and sound among others. The main interest of this study is... BL Stoimenov,S Maruyama,K Adachi,... - 《Tribology International》 被引...
Surface roughness measurement using a surftest SJ-301. The material used in this study is AISI 1045 steel. While analysis of variance (ANOVA) is used to process data. The results showed that the lowest surface roughness can be achieved at spindle speed of 765 rpm, feeding of 0.15 mm / ...
Surface roughnessIn this study, the effect of cutting speed and feed rate on the surface roughness was investigated experimentaly in the machining of AISI 1040 steel being mostly used in industry. Experiments was done by dry turning with uncoated cementite carbite cutting tools at different speeds...

1. what is surface roughness? Answer: surface roughness refers to the micro geometric features of the machined surface of the parts, which are composed of small spacing and peak valley.It is a kind of micro geometry error. 2. how is the surface roughness produced?
Sasaki and Burstein [3] also showed that pitting potential decreased linearly with the grit number that determines the final surface roughness after abrasion. Other experiments using stainless steel have reported similar conclusions of improved corrosion resistance with surface smoothness [4], [5], [6...
A experiment of high-speed milling die steel using cemented carbide ball-end cutter was performed. The influence of cutting parameters such as spindle speed,feed per tooth and radial feed on the surface roughness was investigated,and the roughness formation mechanism under different tool paths was ...
The effects of surface roughness on the low-cycle fatigue life of Type 304 stainless steel at 593°C in air have been investigated. It is observed that, at a strain rate of 4 × 10 3 s 1 and a total strain range of 1 pct, the fatigue life ( N f cycles) decreases with an increa...
