Automated generation of assembly features in layered manufacturing

Purpose The purpose of this paper is to describe an original algorithm for point location of assembly features. Decomposing a model into several parts, for its manufacture using machine‐tools with limited dimensional capabilities, requires appropriate model reassembly. Generating and positioning assembly features are required for interlocked positioning of various parts. Design/methodology/approach An algorithm is presented for the automated generation of assembly features over the decomposition surface. Findings A skeleton‐based point location method is proposed and its results are discussed with respect to placements achieved on a grid. Research limitations/implications The algorithm describes the placement of features on the planar decomposition surface. Future work will allow its generalization to a 3D surface. Practical implications A series of tests made with various parts is described, and an application of this algorithm is presented in a layered manufacturing process. Originality/value This paper describes an original algorithm for point location of assembly features which makes it straightforward to reassemble a decomposed part such as in layered manufacturing.
