This ebook includes chapters on learn paintings performed all over the world within the zone of man-made intelligence (AI) purposes in sheet steel forming. the 1st bankruptcy bargains an advent to numerous AI innovations and sheet steel forming, whereas next chapters describe conventional procedures/methods utilized in numerous sheet steel forming tactics, and concentrate on the automation of these approaches via AI suggestions, corresponding to KBS, ANN, GA, CBR, and so forth. characteristic popularity and the manufacturability overview of sheet steel components, method making plans, strip-layout layout, deciding on the sort and measurement of die elements, die modeling, and predicting die existence are essentially the most vital points of sheet steel paintings. normally, those actions are hugely experience-based, tedious and time eating. In reaction, researchers in different nations have utilized numerous AI innovations to automate those actions, that are lined during this publication. This publication might be necessary for engineers operating in sheet steel industries, and should serve to supply destiny course to younger researchers and scholars operating within the area.

This can be corrected by increasing die radius or blank diameter to allow easier metal flow. (14) Suitability of drawing material should be evaluated on the basis of its coefﬁcient of normal anisotropy. Feature Extraction and Manufacturability … 51 (15) Large draw ratios imply long and thin forming punches that tend to be very susceptible to breakage. This increases the maintenance cost of deep drawing die. (16) The value of deformation should be within 25–75 % of the value of drawability. (17) Vertical axis of blank should be exactly in line with the axis of punch and die during the deep drawing operation.
Deformation features in this class have ISSFs = 0 and ICSFs = 0. This class of features is referred as PureDeformation in the classiﬁcation. A PureDeformation feature can be either interior or boundary (one side, corner, through) based on the interactions of the deformation feature with the outer boundary shell faces of the part. Examples of PureDeformation features (Simple bend (Kannan and Shunmugam 2009), type of hem (Kannan and Shunmugam 2009) in a sheet-metal part are presented in Fig. 23. Partially cut and deformation Features created by lancing and louver operations belong to this category.
Are created by material removal operations such as cutting, punching, stamping, shearing, nibbling, sniping, notching, clipping, blanking, etc. Examples of volumetric features in sheet-metal parts are depicted in Figs. 7 and 8. The volumetric feature thus created has (i) a 2D proﬁle which is used for shearing operation, (ii) end faces which are shared by faces of the base-sheet and the created feature, these end faces are referred as Shared End Faces (SEFs), and (iii) newly created shell faces in the feature as a result of shearing operation are referred as Created Shell Faces (CSFs).
