What the spare parts uses constantly machine to take cutter track line on numerical control lathe:

  (1) the analysis of course taking a knife of car circular arc

   When practical car circular arc, need much knife treatment, excise major surplus first, final ability car goes place to need circular arc. The treatment line with car commonly used circular arc introduces below.

   Graph a flight of stairs of the 1 circular arc that it is a car takes cutter track line.

Graph 1

   Graph 2 (A) the homocentric circular arc of the circular arc that it is a car takes cutter track line.

Graph 2

   Graph the course of cutting of car awl law of the 3 circular arc that it is a car

   Namely first car conic, again car circular arc.

   (2) the analysis of course taking a knife with conic car

Graph 4

   (3) the analysis that feed of the axial when car whorl is apart from

Graph 5

   (4) the analysis of course taking a knife of grooving

   Turning precision is not tall and when the rectangular groove with narrower width, usable Dao Kuan is equal to the recessing knife with wide chamfer, use car of the straight primary feed that take a way to go out. The groove with precision higher demand, use feed car 2 times to become commonly, namely when recessing of first time feed, two side leave groovy wall fine vehicle surplus, use the 2nd times when feed wait for wide knife nap.

   The groove with wider car, can adopt the straight cut that take a way for many times, leave finish machining surplus in groovy wall and underside, vehicle of last knife fine comes dimension. If pursue,6 are shown.
