The ''Iron Butcher,'' which is commonly used in the fish-processing in
dustry for head cutting of fish, is known to be inefficient and wastef
ul, and the resulting product quality may be unacceptable for high-end
markets. This paper describes an innovative machine for fish cutting
that has been developed by us, employing advanced sensor technology, i
mproved control techniques, and properly designed and integrated compo
nents. The new machine eliminates many of the drawbacks of the ''Iron
Butcher.'' The components of the machine, their design, and selection
are described, Integration of the components, and development and oper
ation of the overall system are presented. An economic analysis is giv
en, in order to indicate the cost advantages of the new machine in com
parison with the ''Iron Butcher.''
