The use of [O.sub.2] results in MgO generation in the cut kerf. MgO, due to its high melting temperature, acts as a refractory layer, which precludes the cutting process from penetrating in the lateral and radial directions.
kerf is expressed as sum of wire diameter and twice of wire-work piece gap as given in following equation.
The model is able to calculate yields given increases in diameter, log length, log taper, saw kerf width, and thickness of sawn board, with the restriction that all sawn boards are of equal thickness.
By removing a kerf as thin as 1/8 inch, JRS is able to produce two 13/16 flooring blanks out of some of the thicker boards.
If you notice that the kerf is closing up instead of getting bigger, you have misjudged the lean or the balance of the tree and the tree will fall nowhere near the direction of the undercut.
Independent multiple counterknives replace the spliced cylinder, providing several advantages: precision of the kerf, lightness, duration, limited maintenance and fast positioning.
Chainsaw cutter blades offer the same ease of sharpening as the pseudo blades, but they develop a significantly wider kerf, or width of cut.
Auto Collimation also produces a wider cut kerf on thicker materials, making for easier part removal from the sheet to reduce handling time.
World Bank Country Director for Papua New Guinea & the Pacific Islands, Michel Kerf said, Tonga is ranked second in the world for disaster risk using an index combining exposure and vulnerability, with the transport sector one of the most vulnerable elements.
Advantages of the laser cutting are high quality of the cut surface, narrow kerf width, low heat affected zone and sharp and perpendicular edges.
He notes that while the kerf is larger, the chainsaw can handle surprises better; like nails in the wood.
Cutting resistance when sawing with narrow kerf saws can be influenced by the moisture content and temperature of the wood and the feed speed.
