Pull Manufacturing System Design for Rough Mill Systems: A Case Study
… they may be able to remain competitive through product lead time reduction and on-time delivery to the final customer. Pull based manufacturing is one technique to reduce lead time increase on-time delivery. Value stream mapping was used in this project to evaluate a furniture rough mill …

The margin for yield improvement for no. 1 common 5/4 red oak in a conventional rough mill
… within a conventional (crosscut-first) rough mill. Improvement was measured in terms of volume and also value of cuttings produced. Current levels of yield were obtained from an in-plant yield study of 138 boards. The same material was then processed with a computer optimization program …

Integrating the Least-Cost Grade-Mix Solver into ROMI
Up to 70 percent of rough mill manufacturing expenses stem from raw material (lumber) cost. Rough mill costs can be reduced by optimizing the lumber grade or grades that are purchased. This solution is known as the least-cost lumber grade-mix solution. The least-cost lumber grade-mix solutions has …

Evaluation of color-based machine vision for lumber processing in furniture rough mills
… Tech for lumber processing in the furniture rough mill. The evaluation was done by conducting a yield study using 134 red oak boards. ROMI-RIP, a rip-first simulation program by Thomas (1995), was used to simulate yields for both the manually digitized lumber data and the machine vision …

The potential for short length lumber in the furniture and cabinet industries
… average volume of parts produced per furniture rough mill sawing operation; the regression of board feet per sawing operation was significantly and negatively related to lumber length in 14 of the 18 cutting bill combinations tested. Regression results indicated that as crook decreases, total …

Simulating Optimal Part Yield from No. 3A Common Lumber
… to conduct research on various aspects of the rough mill from processing to recovery efficiency. This research used the ROMI-RIP and ROMI-CROSS simulation programs to determine specific conditions that led to optimal part yield when processing No. 3A Common, 4/4-thickness, kiln-dried, red oak …

Understanding the relationship of lumber yield and cutting bill requirements: a statistical approach
… yield is essential to improve lumber yield in rough mills. This understanding could also be helpful in constructing a novel lumber yield estimation model. The purpose of this study was to advance the understanding of the phenomena relating cutting bill requirements and yield. The scientific …
