If reference is made to "first" or "second", this should be understood to distinguish between features and not to indicate or imply relative importance or to implicitly indicate the number of indicated features or to implicitly indicate the precedence of the indicated features.
Referring to fig. 1, an embodiment of the present invention provides a high-efficiency low-damage processing method, including the following processing steps:
firstly, setting a workpiece to be processed and a processing unit for processing the workpiece;
and then, processing the workpiece by the processing unit at a preset processing speed which is not lower than a processing speed corresponding to the embrittlement of the material of the workpiece.
It is noted that, during high-speed working of a material, internal defects of the material are activated under impact load, resulting in nucleation, propagation and interdigitation of microcracks, and more cracks are generated in the surface layer of the material, resulting in embrittlement of the material. The material resistance of the crack tip generated by the material can be increased along with the increase of the strain rate, the crack is prevented from expanding, the damage depth of the surface of the material is reduced, and therefore the skin effect of subsurface damage is caused by material embrittlement. Fig. 2 lists several fitting curves of material damage depth and material brittleness change, where the horizontal axis of the coordinate is the material brittleness change degree, and the vertical axis of the coordinate is the material damage depth, and it can be seen that as the processing speed or strain rate increases, the material brittleness increases, and the subsurface damage induced by processing is only distributed on the shallow surface layer of the workpiece, so as to reduce the damage depth of the material in the processing process and improve the processing efficiency.
In addition, by fitting a relation curve between the subsurface damage depth and the strain rate of the material, referring to fig. 3, the horizontal axis represents the material strain rate, and the vertical axis represents the subsurface damage depth of the material, and mathematically, the relationship between the subsurface damage depth and the strain rate of the material is:
the relationship between the processing speed of a material and the strain rate of the material is:
where δ represents the depth of the lesion, k1,k2And d epsilon/dt is a dimensionless parameter, the material strain rate of the workpiece and v is the processing speed of the workpiece.
As can be seen from equation (2), the strain rate of the material is directly proportional to the machining speed, and an increase in the speed of the machining unit results in an increase in the strain rate of the workpiece material. k is a radical of2The method is related to the size of the material and the processing depth and can be calculated through a derivation formula.
From the formula (1), it can be seen that the subsurface damage depth of the material is in direct proportion to the negative index of the strain rate, that is, the subsurface damage depth of the workpiece decreases with the increase of the processing speed and gradually approaches to the surface layer, so that the skin effect of the subsurface damage of the workpiece is realized, the subsurface damage of the workpiece can be reduced by increasing the processing speed, the processing efficiency of the workpiece is improved, and the processing quality is optimized.
The skin effect is an inherent characteristic of engineering material damage, namely, in the loading process of a workpiece with high strain rate, the damage (such as cracks, dislocation, phase change) of the material is concentrated in a local loading area and does not expand in a large range, so that in the material processing process, the subsurface damage depth is reduced along with the increase of the processing speed or the strain rate. The preset processing speed is a processing speed corresponding to material embrittlement of the workpiece, and the preset processing speed is a processing speed corresponding to material embrittlement of the workpiece aiming at a plastic material; aiming at hard and brittle materials, the conventional ultra-high speed processing speed (the processing speed is more than 150 m/s) is adopted; for composite materials, this refers to the processing speed at which the plastic components in the material undergo material embrittlement.
The skin effect of material damage exists in the processing of hard and brittle materials, plastic materials, composite materials and other materials. It is noted that the workpiece materials to which the present invention is directed include hard and brittle materials, plastic materials, composite materials, and the like. In the processing process of the hard and brittle material, along with the increase of the processing speed, the brittleness index is increased, the processed cutting chip is gradually reduced, the subsurface damage density is increased, and the depth is reduced; aiming at plastic materials, the plastic deformation of the materials is restrained by the ultra-high speed processing, the materials are removed in a brittle failure mode, the temperature of a processing area is reduced, and the thickness of a deteriorated layer on the surface of a workpiece is reduced. The material is in a high strain rate state in the ultra-high speed machining process, and the brittleness index of the hard and brittle material can be improved or the brittleness index of the plastic material can be realized by utilizing the strain rate hardening effect in the machining process, so that the subsurface damage depth of the workpiece machining is reduced by the skin effect of causing the subsurface damage of the workpiece.
The processing speed corresponding to the embrittlement of the plastic component in the plastic material or the composite material can be judged by observing the shape of the machined chip of the material at different processing speeds (processing strain rates), the section appearance of the chip, the surface hardening degree of the workpiece, the surface quality of the workpiece and the like, so as to judge that the material is in a plastic failure state or a brittle failure state. For example, in the plastic material, as the processing speed increases during processing, the processed chip is converted from continuous to discontinuous, and the chip has the characteristic of brittle fracture, at which point the workpiece is subjected to material embrittlement, so that the processing state of the workpiece is represented by the form of the chip.
In the case of normal low speed processing, the plastic material is removed in the form of a continuous strip of chips, while the brittle material is broken. As the processing speed increases, the plastic material becomes brittle and the chips become jagged or broken from a continuous ribbon. Taking 7050-T7451 aluminum alloy as an example, the aluminum alloy is a plastic material, and when the aluminum alloy is machined at a cutting speed of 1257m/min, chips are obviously jagged, and the aluminum alloy is embrittled.
The embrittlement of the workpiece material is related to factors such as the processing temperature of the workpiece, the processing load applied by the processing unit, the processing depth, the processing speed, the performance of the workpiece, and the like, and the processing speed corresponding to the embrittlement speed of the workpiece material can be obtained through experiments by fixing other parameters and adjusting the processing speed of the processing unit.
Before the workpiece is machined, the machining unit and/or the workpiece can be positioned, so that the machining unit can machine at the preset machining depth and the corresponding machining position of the workpiece, and the machining precision is guaranteed. The processing mode of the processing unit for the workpiece can be selected according to the specific processing technology of the workpiece, such as grinding, turning, milling and the like, and the type of the processing unit can also be selected according to the specific processing technology of the workpiece, such as a grinding wheel, a turning tool, a milling cutter and the like. The processing speed of the processing unit may refer to a moving speed, a feeding speed, a rotating speed, etc. of the processing unit with respect to the workpiece.
The processing mode of the processing unit for the workpiece can adopt a mode that the processing unit moves, rotates or combines the movement and the rotation relative to the workpiece; for example, the processing unit is set as a milling cutter, and the milling cutter moves relative to the workpiece according to a preset track so as to mill the workpiece; or the processing unit is set as a turning tool, and the turning tool is gradually fed relative to the workpiece to realize the turning of the workpiece; or the processing unit is set as a grinding wheel, the edge of the grinding wheel is provided with a grinding edge, and when the grinding wheel rotates and moves relative to the workpiece, continuous grinding force is applied to the workpiece, so that the workpiece is ground. The machining method provided by the embodiment is wide in application range, and can be used for machining the workpiece by selecting a corresponding machining mode according to different machining requirements.
The processing depth of the workpiece has an upper limit, when the processing depth of the workpiece is large, if the preset processing depth is reached by only performing single processing, the damage degree of the workpiece is serious, the processed workpiece is extremely easy to damage, and in order to meet the process requirements of the processing depth and the processing quality of the workpiece, the workpiece needs to be circularly processed for multiple times and gradually fed to the preset thickness.
Specifically, according to the machining depth requirement of the workpiece, a single machining depth is set, and the workpiece is machined successively until a preset machining depth is reached. The single processing means that the processing unit finishes processing the whole surface to be processed of the workpiece on the premise of the preset processing depth. According to the self-property of the material and the specific processing depth requirement, the processing unit can set different processing depths each time, so that the processing depths are suitable for the current workpiece processing situation, and the flexibility of workpiece processing is improved; according to the principle of rough machining and finish machining, a larger machining depth can be set firstly, and the machining depth is reduced step by step along with the increase of machining times, so that the damage depth of the surface of the workpiece is reduced and the surface quality of the workpiece is improved on the premise of ensuring that the workpiece has enough machining depth; in addition, different processing workpieces can be selected for different processing depths to be executed, for example, after a cutter is adopted to cut a certain thickness, the workpiece is ground, so that both the processing efficiency and the processing quality are considered.
In actual production, processing units with different granularities and hardness can be selected to process the workpiece according to the specific processing requirements of the workpiece, wherein the granularity refers to the size of grains used for mainly processing the workpiece in the processing units; the smaller the granularity of the processing unit is, the smaller the damage depth of the workpiece is, the larger-granularity processing unit can realize rough processing of the workpiece, can quickly eliminate the defects on the surface of the workpiece or damage caused in the previous working procedure, and ensures that the surface of the workpiece has certain flatness; the machining unit with smaller granularity can realize finish machining of the workpiece, ensure the integrity and the smoothness of the surface of the workpiece and reduce subsequent machining procedures and machining time. In this embodiment, the workpiece is repeatedly processed for a plurality of times, and the particle size of the processing unit is reduced step by step, so as to ensure the processing efficiency of the workpiece and the surface quality of the workpiece.
In order to further optimize the processing quality of the workpiece, a processing unit with smaller granularity can be selected, the processing speed of the processing unit is improved, the processing speed does not exceed the processing speed corresponding to embrittlement of workpiece materials, and the single processing depth is reduced, so that high-efficiency low-damage processing is realized, and the surface quality of the workpiece is improved.
