1、机械专业中英文文献翻译英文原文Influence factors on the quality of the workplace surfaceProcessing process on the surface quality of the influenceThe vibration of the process system of the influence on the quality of the surfaceIn mechanical processing process technology system sometimes occur vibration, that is, i
2、n the cutting edge tool and workplace is cutting surface except on the name between cutting motion, but also can appear a cyclical relative motion.Vibration that process system by forming movement of the interference and damage, make processing surface appear chatter marks, increases the surface rou
3、ghness value, worsening processing surface quality.Cutter geometrical parameters, materials and cutting quality to the surface quality of the influenceThe cutting tool geometric parameters on the surface roughness of the biggest influence is vice PianJiao, the main point PianJiao, arc radius. Under
4、certain conditions, reduce PianJiao, Lord, vice PianJiao point arc radius can reduce surface roughness. Under the same conditions, carbide cutting tools process of surface roughness value less than high speed steel paper cutting knife, and diamond and CBN) tools and better than hard alloy, but becau
5、se the diamond and iron family affinity materials, it should not be used for processing iron family materials. In addition, the cutting tool before and after the face, cutting knife blade itself directly influence the roughness of the processing the roughness of the surface, therefore, improve the q
6、uality of cutting tool, cutting tool and face, cutting knife blade roughness value should be lower than the roughness of the 1 2 levels.Cutting fluid to the influence on the quality of the surfaceCutting fluid cooling and lubrication effect can reduce the cutting process of interface friction, reduc
7、e the temperature of cutting zone, the cutting metal surface layer of plastic deformation degree down, restrain the develop the thorn and scales produced in the production of different materials for reasonable choice of cutting fluids can reduce the surface roughness.The workplace material on the su
8、rface quality of the influenceThe workplace material nature; Processing plastic materials, the cutting tools for metal extrusion produced plastic deformation, and the cutting tool and workplace forced separation of the torn scraps effect, make the surface roughness value increase. The workplace mate
9、rial tenacity the better, metal, plastic deformation, the bigger the processing surface is the more the rough. Processing brittle material in the chip broken granular, due to the collapse in broken and endows the machined surface left many pitted surface roughness.General toughness large plastic mat

For the same kind of material, the greater the grain size of the organization, the larger the surface roughness. Therefore, in order to reduce the surf

12、ors, including cutting dosages, cooling lubrication. In low speed processing plastic materials, easy to produce the develop and scales thorn, so, improve the cutting speed, can reduce the develop and scales thorn, decreasing part already the surface roughness value; For brittle material, general won
13、t form the develop and scales thorn, so, cutting speed on the surface roughness basically no influence. The increase speed, plastic deformation also increases, the surface roughness increases, so, reduce the speed can reduce the surface roughness value, however, feeding reduced to certain value, rou

Normal cutting conditions, cutting depth on the surface roughness the impact is not big, therefore, mechanical process cannot select the too small cutting depth.Cutting speed on the surface roughness influenceGeneral at the early choose low speed cutting and finishin
15、g choose high speed cutting can reduce the surface roughness. In the medium speed cutting plastic materials, due to easy to produce the develop, and plastic deformation is bigger, so after processing parts surface roughness is bigger. Usually by low or high speed cutting plastic material, can effect

The hardness
