BLACKSBURG, VA - An updated version of the ROMI 4.0 rough mill simulator has been made available by the U.S. Forest Service and Virginia Tech. A free software program, ROMI allows wood products manufacturers to simulate their rough milling processes to improve yield.

According to the two groups, ROMI 4.0 simulates the cut-up of lumber using two common processing modes: rip-first and chop-first. Additionally, ROMI 4.0 allows users to analyze each board’s yield when processed in either rip-first or chop-first mode. The software also allows users to model, simulate, and examine the complex relationship among cutting bills; part dimensions, quantities, and qualities; processing options; and lumber grade mixes. Other improvements to ROMI include a combined rip and chop-option, a new user interface, and improved simulation tracking options, to name just a few.
