In machining, the rake angle is a parameter used in various cutting processes, describing the angle of the cutting face relative to the workpiece. There are three types of rake angles: positive, zero or neutral, and negative. Positive rake: A tool has a positive rake when the face of the cutting tool slopes away from the cutting edge at inner side.
Wood cut in this way is prized for certain applications, but it will tend to be more expensive as well. In cutting a log, quarter sawn boards can be produced in several ways, but if a log is cut for maximum yield it will produce only a few quarter sawn boards among the total; if a log is cut to produce only quarter sawn boards there will be ...
A very popular helix angle, especially for general cutting of metal materials, is 30°. For finishing end mills, it is common to see more tight spiral, with helix angles 45° or 60°. Straight flute end mills (helix angle 0°) are used in special applications, like milling plastics or composites of epoxy and glass.
90º miter joint (pieces ready to be joined) Miter joint of two pipes A miter joint (mitre in British English) is a joint made by cutting each of two parts to be joined, across the main surface, usually at a 45° angle, to form a corner, usually to form a 90° angle, though it can comprise any angle greater than 0 degrees.
Some special angles should be noted or the graphs of two equations should be compared on the same plot. The joint is weakest at α=90° due to tension limits and 45° due to shear limits. However, α=45° will be stronger than α=90° if shear strength is greater than σ/2. The joint is strongest between these two angles at 63.4°.
A type of flat, tapered, single-cut file used to cut, flatten, and smooth (or "float") wood surfaces by abrasion, e.g. when making a wooden plane. Unlike rasps and files, floats have parallel teeth and can be resharpened as many times as the thickness of the blade will allow. flute 1. A deep channel cut in wood. 2. The cannel of a gouge. foxing
A motorized miter saw. A miter saw or mitre saw is a saw used to make accurate crosscuts and miters in a workpiece by positioning a mounted blade onto a board. A miter saw in its earliest form was composed of a back saw in a miter box, but in modern implementation consists of a powered circular saw that can be positioned at a variety of angles and lowered onto a board positioned against a ...
A mitre box or miter box (American English) is a wood working appliance used to guide a hand saw for making precise cuts, usually 45° mitre cuts. [1] [2] Traditional mitre boxes are simple in construction and made of wood, while adjustable mitre boxes are made of metal and can be adjusted for cutting any angle from 45° to 90°.
