The demand for more efficient double layer roll forming machine history manufacturing processes has been increasing in the last few years. The cold forging process of roll forming machines has been presented by some engineers as a possible solution, because it allows the production of roll forming machines parts with a good surface finish. This kind of machine also ensures good mechanical properties. Nevertheless, the roll forming machines cold forming sequence design can be very empirical since it is largely based on the designer experience so that the roll forming machines computational modeling of each forming stage can be very helpful.
Thanks to the roll forming machines finite element methods, we are able to make the sequence design faster and more efficient so that we may finally decrease the use of conventional trial and error roll forming machines production methods. That is why the application of a roll forming machines commercial general finite element software has been applied so as to model a roll forming machines operation. In fact, a number of roll forming machines models have been developed so as to simulate the compression test and to simulate a basic forming operation that is applied in most of the roll forming machines cold forging parts sequences.
The simulated upsetting roll forming machines operation is one stage of the automotive starter in the overall manufacturing process. A lot of experiments have been done to obtain the stress-strain roll forming machines material curve and the material flow can be controlled very well during the simulated stage. This is also the same with the required roll forming machines force as they can be used as model input data and validation of roll forming machines model results. The comparison of these tests confirms that the developed roll forming machines production methodology has great potential in metal forming which is a widely used manufacturing process.
It is mainly noted for its roll forming machines minimum waste and dimensional precision, and it usually improves the mechanical properties of the formed part. However, the roll forming machines working sequence of a new design is by no means a straightforward task, and it requires many trials and adjustments to achieve the satisfactory working conditions. The empirical roll forming machines method has been traditionally applied to metal forming design and this approach is expensive and time consuming and has been gradually taken place by cutting edge roll forming machines production methods.
Computer simulation of the roll forming machines has become reliable and acceptable in the metal forming industry since the late nineteen eighties. Metal roll forming machines analysis can be performed in three modeling scales and the first scale is the global modeling that predicts roll forming machines process loads or work.
