To investigate the workpiece curvature influence on groove deformation,numerical studies with curvature varying from negative to positive were conducted on copper *** deformations were analyzed,including groove geometry,effective stress distribution and plough *** curled groove shape whose workpiece curvature was 0.133 mm-1 was validated by ***,a series of geometry models with various curvatures were introduced to analyze the change of groove *** results show that positive curvatures influence groove deformation more intensively than negative or zero *** is mainly due to the action of the tool forming face during plough process.

In five-axis flank milling operations,the intersecting surfaces of different cutting edges create roughness on the milled surfaces that cannot be ignored in situations with strict requirements,especially in aeronautical *** focus on motion problems in milling operations,this paper presents a new model that utilizes elliptical paths as cutting edge trajectories on 3D surface topography machined by peripheral ***,the cutter parallel axis offset and location angle are considered,which change the location of the ellipse center and intersection point of the cutting ***,through the proposed model,the predicted surface topography is obtained,and the factors that affect the development tendency of roughness are ***,the effects of the cutter location position(CLP)geometric parameters,cutter parallel axis offset and curvature on the roughness are evaluated by a numerical ***,machining tests are carried out to validate the model predictions,and the results show that the surface topography predictions correspond well with the experimental results.
