Description
Technical Field
The utility model relates to the technical field of cutters, in particular to a milling cutter for inhibiting CFRP profile burr defects and a using method thereof.
Background
The CFRP of the carbon fiber composite material has wide application in the fields of high-end equipment such as aerospace and the like due to the excellent performance. However, the CFRP has anisotropic mechanical properties and low interlayer bonding strength, so that the CFRP is a typical difficult-to-machine material, and the common problems in the milling process are that the cutter is fast in wear, and the defects of burrs, layering, edge breakage and the like are easily formed.
In the prior art, a Chinese utility model patent document with a publication number of CN213857298U and an authorized bulletin date of 2021, month 08 and 03 is proposed, and the technical scheme disclosed in the patent document is as follows: a high-speed milling cutter for a carbon fiber component profile comprises a cutter body and a cutter handle, wherein the cutter body and the cutter handle are connected, three blades are distributed on the cutter body, a blade group is formed by the three blades, the cutter teeth of the blades are arranged on the side surfaces, wavy cutting edges are arranged on the cutter teeth, the distance between the center of the first cutter tooth of the blade A and the end of the blade is smaller than that between the center of the first cutter tooth of the blade B and the end of the blade, the distance between the center of the first cutter tooth of the blade B and the end of the blade is smaller than that between the center of the first cutter tooth of the blade C and the end of the blade, and the wavy cutting edges of the three blades are distributed in a staggered manner.
In the practical use process, the following problems can occur: the cutter can effectively improve the machining efficiency, the service life of the cutter is improved by 11.5 times compared with that of a conventional pineapple milling cutter and a left-right rotation staggered end milling cutter, and the machining efficiency is improved by 9 times, but the cutter is used for cutting with a large swing angle and has the damage of layering, burrs and the like.
The current machining tool capable of effectively inhibiting CFRP milling damage comprises:
1) Pineapple milling cutter: the pineapple milling cutter is characterized in that the right-handed cutting edge and the left-handed spiral groove of the seal class are distributed in the circumferential direction of the cutter. Compared with the traditional cutter, the number of the cutting edges participating in cutting per rotation is greatly increased, so that the cutting force of each right-hand cutting edge is reduced. The crossed left and right spiral grooves change the continuous blade into a micro-tooth unit, and the left-hand part of the micro-tooth unit can participate in cutting, so that the normal cutting force is reduced. The left and right blades exert a certain shearing action on the surface layer fibers, but the generation of burrs is not completely suppressed.
2) Left-right hand staggered end mill: the lower part of the cutter is a right-handed cutting edge, and the upper part is a left-handed cutting edge. When in cutting processing, the junction of the upper part and the lower part of the cutter is required to be controlled to be positioned in the center of the thickness of the processed material, so that the axial cutting force of the cutter on the upper surface layer and the lower surface layer of the CFRP is directed to the inside of the material, thereby achieving the purposes of reducing the axial resultant force and removing burrs on the processed surface. However, when the thickness change area is processed, the junction of the upper part and the lower part of the cutter is difficult to control and is always positioned at the center of the thickness of the material, and when the curved surface profile with smaller curvature is processed, the left and right rotary cutting edges cannot cut the material at the same time, and the cutting effect is similar to that of a common end mill, and burrs still exist. Meanwhile, as the number of the cutting edges of the staggered milling cutter is small, the cutting edges are greatly influenced by cutting reaction force, and the cutting edges are easy to wear when cutting the CFRP hard and brittle materials, so that the effect of suppressing burrs of the left-handed cutting edges and the right-handed cutting edges is affected.

Example 4
As a best mode of the utility model, the utility model comprises a milling cutter for inhibiting CFRP profile burr defect, referring to fig. 1 and 2 of the specification, the milling cutter 1 is distributed in a cross shape, and comprises a first pineapple edge 2, a right-hand cutting edge 5, a second pineapple edge 4 and a left-hand cutting edge 3 in sequence along the circumferential direction.

Further, the first pineapple edge 2 and the second pineapple edge 4 are respectively provided with a plurality of first micro-tooth units 6 and first spiral grooves which are arranged between the first micro-tooth units 6 and are intersected. A wedge-shaped included angle is formed between the end surfaces of two adjacent first micro-tooth units 6 and is used for forming a local shearing effect. The wedge angle alpha is in the range of 5 deg.. A plurality of second micro-tooth units 7 are respectively arranged on the right-hand cutting edge 5 and the left-hand cutting edge 3, and second spiral grooves are formed between the second micro-tooth units 7. The first spiral groove is used for removing chips, and the second spiral groove is used for removing cut burrs.
In this embodiment, the left-hand and right-hand are opposite concepts, and when the tool rotates, the spiral line direction of the left-hand finger cutting edge points to the end face of the milling tool 1 downwards, and the spiral line direction of the right-hand finger cutting edge points to the handle of the milling tool 1 upwards. For example, referring to fig. 1 of the specification, when the milling tool rotates clockwise, the first pineapple blade 2, the right-handed cutting blade 5, the second pineapple blade 4, and the left-handed cutting blade 3 sequentially cut CFRP 8 and circulate, and in this process, the present embodiment does not limit the cutting edge for cutting CFRP 8 for the first time, and may be any one of the first pineapple blade 2, the right-handed cutting blade 5, the second pineapple blade 4, or the left-handed cutting blade 3. When the milling tool rotates anticlockwise, the left-hand rotation is changed into the right-hand rotation, and the right-hand rotation is changed into the left-hand rotation, so that the left-hand cutting edge 3 and the right-hand cutting edge 5 are still used in a staggered mode, the right-hand cutting edge 5 is still used for cutting burrs generated by the first pineapple edge 2, and the left-hand cutting edge 3 is still used for cutting burrs generated by the second pineapple edge 4.
A method of using a milling tool to suppress CFRP profile burr defects rotates the milling tool 1 so that the following four stages are completed in sequence and cycled. The four stages include a first pineapple edge 2 cutting stage, a right-hand cutting edge 5 cutting stage, a second pineapple edge 4 cutting stage, and a left-hand cutting edge 3 cutting stage. The cutting may be started with any one of the stages as an initial stage. More specifically, during the cutting stage of the first pineapple blade 2, referring to fig. 3 of the specification, the shearing resultant force formed by the adjacent first micro tooth units 6 of the first pineapple blade 2 is downward, and the CFRP 8 material is subjected to the downward axial resultant force, so that the formation of burrs on the upper surface can be inhibited. In the cutting stage of the right-hand cutting edge 5, referring to fig. 6 of the specification, the cutting axial force is upward, so that the burrs on the lower surface formed by the first pineapple edge 2 can be removed. In the cutting stage of the second pineapple blade 4, the shearing resultant force formed by the adjacent first micro-tooth units 6 of the second pineapple blade 4 is upward, and referring to fig. 5 of the specification, the cfrp 8 material is subjected to the upward axial resultant force, so that the formation of burrs on the lower surface can be inhibited. In the cutting stage of the left-hand cutting edge 3, referring to fig. 4 of the specification, the cutting axial force is downward, so that the upper surface burr formed by the second pineapple edge 4 can be cut off.
Further, the milling tool was compared with conventional pineapple milling tools and staggered milling tools, and referring to fig. 7 of the specification, the test adopts a back milling scheme, and the feed direction of the test tool is 45 degrees with the fiber direction angle of CFRP 8. In the cutting process, syntilo 9828 cooling liquid is adopted for cooling, the rotating speed of a main shaft is 9000r/min, the feeding is 1000mm/min, the cutting depth is 3mm, and the cutting width is 3mm.
By contrast, referring to fig. 8 to 10 of the specification, in forming edge burrs: the pineapple milling cutter processing upper and lower surface burrs have the largest proportion and the largest burr length, the staggered milling cutter processing burrs have the smallest proportion and the smallest burr length, and the lower surface does not generate burrs. Experiments prove that the milling cutter 1 of the embodiment has the best effect of suppressing burrs on the upper surface and the lower surface, and is secondarily an interlaced milling cutter, and the pineapple milling cutter is the worst.
Referring to fig. 11 of the specification to fig. 14 of the specification, in terms of service life of the cutters, wear of each cutter is observed under the condition of different cutting lengths, wherein the cutter teeth of the pineapple milling cutter and the left-right staggered milling cutter are worn seriously when cutting for about 4m, and the cutter teeth reach the scrapping standard. However, the milling cutter 1 of the present embodiment only has slight abrasion of the first pineapple edge 2 and the second pineapple edge 4, and can still be used continuously until the cutting length of the cutter reaches 8m, and the abrasion of the dense tooth milling cutter reaches the scrapping standard, which indicates that the service life of the milling cutter 1 of the present embodiment is longer than that of the conventional pineapple milling cutter and the left-right-handed staggered milling cutter.
By comprehensively evaluating the formation condition of the burr defect and the service life of the cutter, compared with the traditional milling cutter, the milling cutter 1 of the embodiment has great advantages in inhibiting the burr defect, and the service life of the cutter is improved by 1 time.
In view of the foregoing, it will be appreciated by those skilled in the art that, after reading the present specification, various other modifications can be made in accordance with the technical scheme and concepts of the present utility model without the need for creative mental efforts, and the modifications are within the scope of the present utility model.
