The article cuts the basic file law in operation method, planar file law and law of curved surface file to make one introduction to file. File cuts rough machining of law of 1 basic file (rasp) : Be more than when mental allowance 0.

When 5mm, the thick tine that chooses 300mm, 350mm commonly, medium tine file undertakes big cutting measures treatment, with purify workpiece surplus more part. Fine treatment file cuts (fine file) : Upright when mental allowance at 0.

5 ～ 0.

When 1mm, the serration file that chooses 250mm, 300mm commonly undertakes small cutting measures treatment, in order to be close to the requirement measure of workpiece. Finish machining file cuts () of file of essence of life: Be less than when mental allowance 0.

When 1mm, file of the serration that chooses 200mm, 250mm commonly, double serration and plastic file undertake to workpiece nap sex is machined, in order to achieve work requirement measure. Whole journey file cuts: When the file is advanced, its journey length is close to file face length basically. Use at rasp and fine file treatment commonly (1) seeing a picture. Short distance file cuts: When the file is advanced, its journey length is the 1/2 ～ 1/4 of file face length only. Use at file of essence of life to machine commonly (2) seeing a picture. Law of 2 planar file is fore-and-aft file law: The file presses direction and workpiece face the file of parallel of fore-and-aft center line cuts a method (3) seeing a picture. Transverse file law: The file presses direction and workpiece face the file with fore-and-aft center perpendicular line cuts a method (4) seeing a picture. Alternate file law: The file presses direction and workpiece face fore-and-aft center line intersects 75 ° of ～ of ° of one angle A(35) , and 90 ° file cuts inverting to cut a method in order to obtain the file of alternate file grain (5) seeing a picture. The horizontal stroke pushs file way: File cutter hub and workpiece surface are fore-and-aft central line is perpendicular, and push way to it parallel file cuts a method (6) seeing a picture. Active file law: Will flat file serves as passive style mix to hold go up in vice, form and structure lesser workpiece uses a hand to grasp as active put oneself in another's position hold put on file face, use fore-and-aft drive or pull move the file that has machining to cut a method (7) seeing a picture. Axial of ① of law of file of face of the circular arc outside law of file of 3 curved surface extends file law: The file is advanced direction and outside axes of circular arc face is parallel, the surplus part file outside machining circular arc borderline becomes polygon. Use at commonly outside the rasp of circular arc face is machined (8) seeing a picture. ② Zhou Xiangzhan becomes file law: The file is advanced direction and outside axis of circular arc face is vertical, the surplus part file outside machining circular arc borderline becomes polygon. Use at commonly outside the rasp of circular arc face is machined (9) seeing a picture. ③ axial is slip file law: The file is being made with outside of direction of parallel of axes of circular arc face when advancing, the circular arc outside making an edge at the same time is faced right or of towards the left slip. Use at commonly outside the file of essence of life of circular arc face is machined (10) seeing a picture. ④ Zhou Xiang swings file law: The file is being made with outside axis of circular arc face is vertical of direction when advancing, the right hand makes what file power controls below face of edge circular arc swing at the same time. Use at commonly outside the file of essence of life of circular arc face is machined (11) seeing a picture. ① of law of file of circular arc face synthesizes file law inside: When face of the circular arc inside the file that use a circle or semicircle file treatment, the file completes 3 kinds of exercise at the same time, namely file and inside axes of circular arc face is advanced parallelly, the oneself of file cutter hub rotates (suitable hour hand or anticlockwise direction) and the circular arc inside file edge is faced right or of towards the left slip. Use at commonly inside the rasp of circular arc face is machined (12) seeing a picture. ② horizontal stroke pushs slip file way: The cutter hub of round file, semicircle file and inside axes of circular arc face is parallel, push way to it perpendicular, face of the circular arc inside the edge undertakes sliding file is cut. Use at commonly inside the file of essence of life of circular arc face is machined (13) seeing a picture. Vertical bend of ① of law of spherical and basic file is transverse and slip file law: The file has placed fore-and-aft banking angle to spend A according to globose radius SR, keep stable in motion. When the file is advanced, cutter hub is made at the same time slide from left rightward. Attention: But will spherical divide roughly undertake for 4 area symmetrical file is cut, ordinal loop file is cut to spherical acme (14) seeing a picture. ② list is perpendicular swing file law: The file places A of good list angle according to globose radius SR, keep stable in motion. When the file is advanced, the right hand makes next perpendicular pressing at the same time of file handle swing. The note is Alexandrine (15) seeing a picture. CNC Milling
