Computerized Automation and Controls in Meat Processing
Published in Gauri S. Mittal, Computerized Control Systems in the Food Industry, 2018
The carcass is conveyed from the evisceration module to the splitting saw module, where it is automatically split into two sides using a bandsaw mounted on an articulated frame. Pressure sensors locate the spine at the pelvis, and four guide rollers attached to the frame engage the carcass beneath the spine. The saw blade then engages the vertebra and begins the splitting procedure. The frame travels beneath the carcass using the guide rollers and pressure sensors to accurately constrain the spine. The saw separates the carcass through the mid-sagittal plane. The sides are then conveyed to manual trim and weighing stations. This procedure has two major advantages. First, it eliminates a manual operation that requires the operator to use a large saw, and second, it is more accurate in cutting along the mid-sagittal plane than the manual operation, particularly when operator fatigue sets in.
Making doors and doorframes

If the timber is in a sawn state, as is usual in joinery workshops — it must first be selected and cut to initial lengths with either a crosscut — or hardpoint-saw, a portable, powered crosscut/mitre saw, a portable circular saw, or a travelling-head crosscutting machine. Then, to produce the sawn, sectional sizes (which usually have at least 6mm added to the finished sizes for planing), it will need to be deeped and/or flatted (flat-sawn along the grain lengthwise, parallel to the face-edges of the timber) with either a narrow bandsaw machine (using the widest blade available to avoid snaking), or a realistically-robust circular saw-bench machine.

Specimens were cut from the plates using a bandsaw with a high-speed steel blade and cutting oil. Measurements of width and thickness were obtained with a digital caliper at 30 mm from both ends and at center of the specimens. The thick specimens have an average width of 24.9 ± 0.3 mm and an average thickness of 20.1 ± 0.4 mm. The thin specimens have an average width of 25.3 ± 0.2 mm and an average thickness of 9.5 ± 0.2 mm. The average length of both specimens is 180 ± 1 mm and was measured with a ruler. The specimen geometry was designed in accordance with the criterion of strain equivalence between arms (see Equation 19) although a high precision thickness of the composite materials is impracticable. An anti-friction material was applied between the metal plate and the adhesive in order to produce a pre-cracked region of 50 mm length.
