[0052] Example
[0053] A 230MeV superconducting proton cyclotron adopts a four-sector spiral sector magnetic pole structure, with a total of 8 magnetic poles up and down. The inner radius of each magnetic pole is 160mm, the outer radius is 850mm, and the two sides are spiral. The physical design requires the use of magnetic poles. Magnetic field correction is carried out in the method of side chamfering, and the chamfering angle is 45 degrees, such as figure 2 As shown, the physical calculation gives a curve of the chamfering depth changing with the radius as follows figure 1 shown, for the machining of magnetic pole chamfers. Solidwork and other 3D modeling software cannot accurately give the cutting model of the chamfering depth changing with the radius. It is necessary to borrow the Boolean operation of the software to generate the cutting model. The steps are as follows:
[0054] Step 1, first calculate a shape body with chamfering of the side of the magnetic pole of t...
