The cutting of wood includes sawing, planing, chiseling, milling, turning, drilling and CNC machining. The following describes the commonly used wood cutting methods and tools.
Cutting of wood
(1) Wood sawing: Wood sawing is to open, decompose, and truncate large logs, plates or squares according to design requirements. It is the most used method in wood forming processing. .
The tools used for wood sawing mainly include hand saws, hand-held power saws and sawing machines. Among them, hand saws can be divided into frame saws, knife saws, transverse saws, side saws, panel saws, narrow hand saws, wire saws, etc. according to their structure, among which the most commonly used are frame saws and knife saws; hand-held electric saws include electric circular saws , electric chain saws, electric knife saws and electric jig saws, etc.; sawing machine tools can generally be divided into two categories: band saws and circular saws. The band saw machine is to wind a closed thin steel belt with serrations on two saw wheels to make it move at high speed to realize the cutting and sawing of wood. On this machine tool, not only can sawing along a straight line, but also a certain jig sawing can be achieved. The circular saw is a machine tool that uses a high-speed rotating circular saw blade to saw wood. It has a simple structure, easy installation, convenient operation and maintenance, and high production efficiency, so it is widely used.
(2) Planing of wood: Planing is one of the main technological methods of wood processing. The sawn surface of wood is generally rough and uneven, so planing must be performed to obtain components that are accurate in size and shape, and have a smooth surface.
Wood planing processing is to use the relative movement of the sharp planer edge and the wood surface at a certain angle to the wood surface to peel off the thin layer of the wood surface to complete the wood planing process.
The tools used for planing mainly include woodworking planers, hand-held electric planers and planing machines. Woodworking planer is a commonly used hand tool: hand-held electric planer is a hand-held electric tool that is driven by a single-phase series-excited motor through a transmission belt to carry out planing operations. ; Planing machine tool is driven by the cutter shaft to rotate the planer at high speed for cutting.

(3) Chiseling of wood: The basic form of the combination of wood product components is the frame tenon hole structure. The chiseling of tenon holes on the wood product components is one of the basic operations of wood product molding.
Wood chisel processing is to use the impact movement of the chisel, so that the sharp edge cuts the wood fiber vertically and enters it, and continuously discharges the wood chips, and gradually processes the required square, rectangular or round tenon L.
The tools used in wood chisel processing mainly include wood chisels and tenon machines. Woodworking chisels are divided into flat chisels, round chisels and oblique chisels according to the shape of the cutting edge, among which flat chisels are used the most; The rotary motion (drilling) of the drill is formed by combined machining.

(4) Milling of wood: Various curved surface components in wood products have a complicated manufacturing process, which is generally carried out on a woodworking milling machine. Woodworking milling machine is a kind of universal equipment, which can complete various kinds of processing. In addition, the woodworking milling machine can also be used for various operations such as sawing, tenoning and profiling milling. It is one of the indispensable equipments in the forming and processing of wood products.
(5) Computer numerical control cutting of wood (CNC cutting): Computer numerical control cutting is to install the cutting head on a head around six rotating axes, and complete the carving of wood products of different shapes through computer-controlled cutting tools. Labor saving and high efficiency.
