Summary:A frictional parameter (μ) which varies locally is used to simulate the effect of a clamping or forming tool in the production of plastic plates. Vehicle parts formed by deep-drawing, bending, pressing, stamping, rolling a coil roll sheet. These manufacturing processes are sensitive to friction between the plate and the tools used. A locally stochastic variation of the frictional parameter, based on lubricant distribution or empirically from a strip tensile test may be used to specify a lubricant, quantity or treatment, or identify the process robustness. The friction parameter may be static or sliding and may be a constant or a function of the relative velocity, force and pressure between the plate and tool. Lubricants have been shown to reach a saturation thickness, and accumulate below a vertical coil at the edge. The plate may then be cleaned to remove lubricant or a micro-lubricating process be performed.
