Precision Control Calculation Method and Forming Technology of Aluminum Alloy Base


Article Preview

The step size tolerance for the two-sided forming base complex parts is ±0.1mm, and sharp corners of and roots are required for the 12 vertical facades and edges. Therefore,it is difficult to guarantee the products quality by conventional extrusion. In this paper, the new calculation methods about scaling rates were adopted to control the size of the mould, and computer simulations were carried out for analyzing the forming processes for the extrusion. This method can meet the requirements of the product, improve the performance and material utilization rate, which might replace the machining methods used conventionally.
