The main task that numerical control working procedure designs is farther contrail of means of clamp of dosage of the treatment content this working procedure, cutting, tooling, fixed position and cutting tool motion comes down certainly, make good preparation for work out machine program. Course taking a knife is cutting tool the athletic contrail in whole treatment working procedure, it not only the content that included labor situation, also reflect a labor situation order. Course taking a knife is one of basises that write a program. The following should notice when certain route taking a knife: 1. Seek course of the shortest treatment, reducing empty knife time to if machine graph 1a place to show the hole on the spare parts,be led in order to heighten treatment effect is. After the line is the road taking a knife that B pursues to machine outer lane aperture first, aperture of rework inner ring. The course taking a knife that if convert,C pursues, can save fixed position time nearly one times. Abc pursues the design of 1 the shortest course taking a knife 2. To make sure the surface roughness after workpiece outline surface is machined asks, final outline should arrange successive in taking a knife for the last time treatment to if graph 2a is,come out to use what cut means to machine lumen all right to take cutter track line, this kind walks along a knife to be able to excise the overall surplus in lumen, do not take dead space, do not hurt outline. But rudimental height leaves between the starting point that cuts a law to will take a knife in two all right and terminus, and the exterior surface roughness that short of asks. If use what B pursues,take cutter track line so, use first cut a way all right, cut one knife along Zhou Xianghuan finally, light makes outline appearance, can achieve better result. Graph 2c also is way of a kind of better course taking a knife. Abc scheme takes cutter track line 3 kinds when 2 mill cut lumen 3. Consider cutting tool into, retreat a knife (cut, cut) of course cutting tool be cut or cut a dot to should be on the tangent of outline of edge spare parts, in order to make sure workpiece outline is smooth; Should avoid perpendicular on workpiece outline face on, leave a sword and cut workpiece surface; The time-out in decreasing to machine cutting process in outline as far as possible (abrupt change creates cutting force flexibility is out of shape) , lest leave knife mark, if pursue,3 are shown. Graph 3 cutting tool are cut with the extension when be being cut 4. After the choice makes workpiece is being machined, be out of shape small line accumulates small long and thin part or laminose spare parts to should be used to cross section divide treatment taking a knife to final measure or arrangement of law of symmetrical purify surplus to take cutter track line. 5. Arrange pair of workpiece tigidity to destroy lesser labor situation first CNC Milling
