The scroll plate is the most central component of the scroll compressor, and the processing precision of the scroll plate directly influences the working performance of the scroll compressor. At present, the workpiece material of the scroll plate mainly comprises alloy cast iron and aluminum alloy, and the cutting manufacturability is poor due to the material performance characteristics. Meanwhile, the complex profile structure of the scroll is also an important factor influencing the cutting quality and precision of the scroll.

Because the turbine disc blank pre-casting groove is deep, a milling cutter with a larger long diameter needs to be selected, and the cutting of the cutter is mostly full cutting; when the milling cutter rotates along the vortex path for cutting, the end edge and the peripheral edge of the milling cutter need to process two side surfaces and the groove bottom surface of the vortex disc at the same time, so that the forward milling and the backward milling are alternately carried out during the cutting of the milling cutter; meanwhile, the cutting tool often generates phenomena of breakage and breakage of the cutting edge, breakage of the cutting tool and the like due to factors such as mechanical impact, cutting vibration and uneven cutting stress; in addition, due to the elastic-plastic deformation of the cutting layer metal, the friction between the cutter and a workpiece and chips is large, the cutting temperature is high, and the phenomena of chip accumulation, bonding damage and the like of the cutter are caused due to high temperature, so that the service life of the cutter is influenced.
For the processing of the cast iron scroll, because the alloy elements of the material are more (such as chromium is less than or equal to 0.25 percent and nickel is less than or equal to 3 percent), the hardness of the workpiece is relatively higher (HB 201-255), and according to the technical characteristics of full-cutter cutting, the conventional milling cutter processing has the disadvantages of high cutting difficulty, serious cutter abrasion and short cutter service life. Therefore, it is necessary to design a rough milling cutter with a wavy edge for machining a cast iron scroll to solve the problems of cutting vibration and large impact load of the cutter, so as to improve the cutting efficiency and prolong the service life of the cutter

In the specific implementation: the number of cutting edges of the cutting edge part 1 is generally 4-6, and the diameter d2 of the cutting edge part 1 is 10-20 mm; however, since the more the milling cutter teeth, the more the grooves, the more the rigidity and strength of the cutter itself are reduced, and the wave edge milling cutter is often used for full cutting in heavy load machining, the cutting edge length l of the cutting edge portion 1 is generally 3 to 4 times the diameter d2, and the core thickness d0 of the cutting edge portion 1 is generally 70% of the diameter d2, in order to ensure the rigidity of the wave edge milling cutter and the stability of the cutting process.
The intersection lines of the chip grooves 4 and 6 and the solid part of the cutter form a plurality of cutting edges; the cutting edges are uniformly distributed in the radial direction relative to the center of the front end surface of the cutting edge part 1; wherein, the cutting edge is composed of an end edge 7, a peripheral edge 9 and a tool nose R angle 8 for connecting the end edge and the peripheral edge, the radius R of the tool nose R angle is generally set to be 0.3 mm-0.5 mm; the cutter point R angle 8 greatly improves the cutter point strength of the joint of the end edge 7 and the peripheral edge 9, effectively reduces or eliminates the possibility of tipping of the cutter point of the cutter, enhances the cutting performance of the cutter and prolongs the service life of the cutter; the end edge concave angle of the cutting edge part 1 is set to be 1 degree, so that the end face of the milling cutter can be effectively prevented from being collided with the bottom surface of a workpiece, and cutting and chip removal are facilitated; the end edge 7 and the peripheral edge 9 are provided at the tip with a rake face 10 and a straight flank face 11, and the first relief angle α of the end edge 7 and the peripheral edge 9 of the cutting edge part 1 is set to overcome the friction between the flank faces of the tool end edge 7 and the peripheral edge 9 and the cutting surface1Set to 10-12 DEG, and a second relief angle alphao1Is 18-20 degrees.

At present, for the wave making technology of the existing wave blade milling cutter, the spiral direction of the wave blade is opposite to the spiral direction of the groove, namely the groove is made into right-handed rotation, and the wave blade is made into left-handed rotation. However, as for rough milling processing of the pre-cast groove of the cast iron turbine disc blank, experiments prove that, as shown in table 1, taking a 6-blade rough milling cutter with a cutting edge part 1 with a diameter of 11.15mm and a nose R angle with a radius R of 0.3mm as an example, compared with different-blade wave-making grinding modes, when the grinding spiral direction of the wave blade is the same as the spiral direction of the groove of the cutter, the service life of the cutter is improved by about 30% compared with that of the wave-making milling cutter of the existing wave-making mode, so that the reasonability and reliability of the design of the wave-making rough milling cutter are fully explained, the rough milling processing efficiency of the pre-cast groove of the alloy cast iron turbine disc blank can be effectively improved, and the service life of the cutter.
