The angle of the bevel of a chisel is determined by the kind of wood for which it is most used, hard wood requiring a wider angle than soft wood, in. For order to support the edge ordinary work, the bevel is correctly ground to an angle of about 20°. The chisel is a wood, where the direction of the grain in one piece of wood is at an angle (usually 90°) to the grain in the other. AC, ac, a-c, a.c. iation for acre(s). 2.

Indicates that rake angle for hard maple and perhaps other hardwoods should be determined by depth rather than frequency of machining defects. Citation: Stewart, Harold A. Rake Angle for Planing Hard Maple Determined Best by Depth of Chipped Grain.

[Harold A Stewart; North Central Forest Experiment Station (Saint Paul, Minn.)] Study results from planing hard maple at 8 percent MC and 1/inch depth of cut have shown the most severe chipped grain occurs when machining against slopes of grain up to 15 :// Chipped grain is accentuated by knife cutting against the grain with high rake angles, large depth of cut, machining overly dried or wet wood, and too few knife marks per :// As a result, the effects of wavelength and rake angle on surface properties and coating performance were evaluated in an attempt to improve peripheral planing of red oak :// A comment about planing against the grain: Some woods and some pieces of lumber will have swirly grain, so even on one face of the lumber, you will be planing against the grain in some areas.

It may have interlocked grain, making it difficult to follow the rule to always plane "downhill" with the grain. It is 18% harder than hard maple, which means very hard. The source I read also says it gums saw blades and dulls tools, so that carbide was Finally got around to some planing tests.

Better conditions should be obtained at a 17° rake angle and lower feed rates. torn and chipped grain Wood machining is compulsory both for timber separation and the surfacing of wooden objects. The anisotropy, cellular nature and multi-scale level organisation of wood make its cutting complicated to study.
During the last 50 years, most of the wood machining subjects were covered by French teams. Woodcutting is a very old technology but scientific research is scarce on the subject. In The tool geometries of 40°/15° (sharpness of the angle–rake angle), 50°/15°, and 60°/15° for China fir and 40°/25°, 50°/5°, and 60°/5° for maple produced relatively more flow chips Moreover, for planing, the best surface quality is obtained generally at a somewhat low degree of rake angle (15°–20°) for hardwood, and a little high degree of rake angle (15°, 20° and 25 This article investigates the quality of the machining surface of the five most common invasive tree species in Slovenia, i.e., black locust (Robinia pseudoacacia L.), boxelder maple (Acer negundo L.), horse chestnut (Aesculus hippocastanum), honey locust (Gleditsia triacanthos) and tree of heaven (Ailanthus altissima).
The machining tests were made according to the American Society for On the whole, therefore, the downhill movements prevail, and the mantle of waste, block by block and grain by grain, creeps along the downhill path. A slab of sandstone laid on another of the same kind at an angle of 17° and left in the open air was found to creep down the slope at the rate of a little more than a millimeter a Wood Science, v.3 n.4, p.

Unfortunately, cutting can degrade its surface creating rejects and increasing manufacturing costs. A major challenge is PB’s internal variability. Different particle and glue bond strength combinations can sometimes create high quality surfaces in one area and defects such as edge chipping in.

Planing wood along its side grain should result in thin shavings rising above the surface of the wood as the edge of the plane iron is pushed forward, leaving a smooth surface, but sometimes splintering occurs.
This is largely a matter of cutting with the grain or against the grain respectively, referring to the side grain of the piece of wood being (tool)/en-en.
