We are machining aluminium plates about 100mm x 600mm x 4mm thick which we affix to a jhttp://www.practicalmachinist.com/vb/images/attach/jpg.gifig and are machining off 0.5 mm from one side with a face mill. The material is previousy cut with a Guilliotine and we believe that this is leading to an ubnormal stress which causes the part to bend. We have produced the same thing from material cut with a bandsaw without this problem. Can somebody suggest an annealing process to try to subject the slabs before the machining? Temperature and time? Many thanks for any input.
