A thickness planer is a woodworking machine to trim boards to a consistent thickness throughout their length and flat on both surfaces. It is different from a surface planer, or jointer, where the cutter head is set into the bed surface. A surface planer has slight advantages for producing the first flat surface and may be able to do so in a ...
Craftsman No. 5 jack plane A hand plane in use. A hand plane is a tool for shaping wood using muscle power to force the cutting blade over the wood surface. Some rotary power planers are motorized power tools used for the same types of larger tasks, but are unsuitable for fine-scale planing, where a miniature hand plane is used.
A jointer cannot be used to create a board of even thickness along its length. For this task, after jointing one face, a thickness planer is used. Thickness planers and jointers are often combined into one machine, with the work piece passing underneath the same rotating blade for thicknessing, but in the opposite direction.
The term planer may refer to several types of carpentry tools, woodworking machines or metalworking machine tools. Plane (tool), a hand tool used to produce flat surfaces by shaving the surface of the wood; Thickness planer (North America) or thicknesser (UK and Australia), a woodworking machine for making boards of even thickness
Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.
Thus the basic influence parameters for the forming limits are, the strain hardening exponent, n, the initial sheet thickness, t 0 and the strain rate hardening coefficient, m. The lankford coefficient, r, which defines the plastic anisotropy of the material, has two effects on the forming limit curve. On the left side there is no influence ...
The founder Frank Reginald Durden produced his first woodworking machine, a thickness planner, in 1951. This was quickly followed with the introduction of the popular "Pacemaker" universal woodworker in 1954. Several models of the 'Pacemaker" were produced in the ensuing years and exported to different countries around the world.
The smoothing plane is the shortest of the bench planes. [2] Under the Stanley Bailey numbering system for metal-bodied planes #1 to #4 are smoothing planes, with lengths ranging from 5 + 1 ⁄ 2 inches (140 mm) to 10 inches (250 mm). [3]
