A computerized press control and data gathering program developed at the USDA Forest Service, Forest Products Laboratory, allows researchers to manipulate small changes in the pressing variables for wood-based composites and to observe the responses. Knowledge of a few basic principles permits the researcher an opportunity to use complex computer programs. This report describes 1) segmented programs capable of controlling a press in conjunction with auxiliary (steam injection) devices; 2) means of acquiring a smooth transition from the dynamic to the static mode of control; and 3) techniques for collecting critical data.
