systems for meat processing, is the inability of existing equipment to
adapt to varying sizes and shapes of products. This usually results
in less than desirable outcomes when measured in terms of yield of
the operations. In poultry processing for example, the initial cut of
wing-shoulder joints is the most critical step in the deboning
process. Two approaches for determining a trajectory for the cut is
presented. The first is a technique using x-ray and visual images to
obtain a 2-D model that locates the shoulder joint with respect to
the surface features of the product. The second approach is
obtained by determining a 3-D cutting trajectory and the associated
forces/torques using a motion analysis system and a force/torque
sensor incorporated with a knife. We then discuss the potential
application of these results in the design of an automated cutting
system that uses the obtained trajectory as a nominal cutting path.
The system would make'adjustments during the cut using force
feedback so as to emulate the manual cutting process
Research on surface roughness of circular arc cut by ASJ
Izrađen je potpuni faktorijalni plan eksperimenata za istraživanje učinaka tlaka mlaza, reznog posmaka i polumjera kružnog luka na površinsku hrapavost kružnog luka rezanog mlazom abrazivne otopine - abrasive suspension jet (ASJ). Ortogonalnim planom eksperimenata analizirala se veličina djelovanja parametara na hrapavost rezne površine na različitim dubinama. Smanjivanje brzine prijelaza je najučinkovitija metoda za smanjenje površinske hrapavosti. Uz to, usporedbom topografije rezne površine s onom pomoću AWJ, ustanovilo se da je površina sastavljena od četiri zone: inicijalna zona, glatka zona, prijelazna zona i gruba zona. Konačno, primijenjena je metoda multipne linearne regresije za postavljanje modela hrapavosti površine na različitim dubinama, što se eksperimentima potvrdilo kao pouzdano. Zaključci mogu poslužiti kao teorijski vodič za poboljšanje učinkovitosti rezanja pomoću ASJ.Full factorial design of experiments was developed in order to investigate the effects of jet pressure, cutting feed, and circular arc radius upon the one response variable surface roughness of circular arc cut by abrasive suspension jet (ASJ). And orthogonal design of experiments was used for analysing the magnitude of effects of parameters on roughness of the cutting surface at different depths. Slowing down the traverse speed is the most effective method to reduce the surface roughness. In addition, comparing the topography of the cutting surface with that by AWJ, it is found that the surface also consists of four zones: initial zone, smooth zone, transition zone and rough zone. Finally, the multiple linear regression was employed to establish the model of cutting surface roughness at different depths, which was proved to be reliable by experiments. The conclusions can provide theoretical guidance for improving the cutting efficiency of ASJ
