Numerical control process designing decides cutter track line and arrangement treatment are ordinal

3a place notifies the aperture department on the spare parts. 2.

After the line is the road taking a knife that 3b pursues to machine outer lane aperture first, aperture of rework inner ring. If convert 2.

The course taking a knife that 3c pursues, reduce empty knife time, can save fixed position time nearly one times, rose to machine efficiency. 2 attempts of line of 1c) of course of B) of A) hardware design 2.

The design of 3 the shortest courses taking a knife 2, final outline walks along a knife to finish the surface roughness after be being machined to assure workpiece outline surface to ask, final outline should arrange successive in taking a knife for the last time treatment to come out. If pursue 2.

4a takes cutter track line to use what cut means to machine lumen all right, 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. So if use 2.

The course taking a knife that 4b pursues, use first cut a way all right, cut one knife along Zhou Xianghuan finally, light makes outline appearance, can achieve better result. Graph 2.

4c also is way of a kind of better course taking a knife. Course of 3c) of course of A) course 1b) 3 graphs 2.

3 kinds of of 4 milling lumen courses taking a knife 3, the choice cuts those who cut a direction to consider cutting tool to enter, retreat a knife (cut, cut) when the course, of 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 2.

5 are shown. Graph 2.

5 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. When arranging labor situation, ying Xianan discharges pair of workpiece tigidity to destroy lesser labor situation. CNC Milling
