The first step of machine selection is to choose the cutting machine according to desired production rate. I will consider production per shift, as the number of windows or doors produced per eight hours. In order to choose the right cutting machine, you will need to consider production rate, profile details, and cutting type.
Note that machine selection in the options below can be flexible due to different cutting machine manufacturers. Here I will take our products as a reference.
