Detailed Description
The first embodiment is as follows:
the embodiment provides a multi-energy-field nano lubricant microscale bone grinding processing measurement system, which comprises an ultrasonic vibration device I, a fluid charge atomization device II, a measurement device III, an air floatation platform device IV and a three-dimensional displacement workbench, wherein the air floatation platform device IV is arranged at the bottom of the three-dimensional displacement workbench, and a workpiece II-2 is clamped on the three-dimensional displacement workbench through a clamp II-1, as shown in FIG. 1.
In the embodiment, the long bovine bone is selected as a sample material, and the ultrasonic vibration device I is adopted to process the long bovine bone through an ultrasonic-assisted micro-grinding process aiming at the characteristics of large grinding force and easiness in occurrence of brittle fracture and crack damage in the processing process.
As shown in FIG. 2, the ultrasonic vibration device I comprises an ultrasonic generator I-1 and an ultrasonic electric spindle I-2, an ultrasonic transducer I-3 in the ultrasonic electric spindle I-2 is connected with the ultrasonic generator I-1 through a lead, and alternating current of the ultrasonic generator I-1 provides a high-frequency electric vibration signal for the ultrasonic transducer I-3.
The shell of the ultrasonic electric spindle I-2 is connected with an angle adjusting device to adjust the grinding angle, and meanwhile, the angle adjusting device is also arranged on the three-dimensional displacement workbench and moves in the direction X, Y, Z. The angle adjusting device is the prior art and is not described herein again.
The grinding tool I-5 is connected with an amplitude transformer I-4 of the ultrasonic vibration device I, so that the grinding tool I-5 can generate vibration meeting the processing requirements. When the grinding tool I-5 is close to the bone material, the volume of the grinding tool/bone gap is reduced, and cooling liquid is discharged from the gap to take away heat and bone grinding dust; when the abrasive article I-5 is removed from the bone material, the interstitial volume increases, thereby bringing fresh coolant in. The ultrasonic vibration device I is arranged on the main shaft and rotates along with the main shaft, the ultrasonic vibration assisted micro-grinding can enable cooling liquid in a grinding area to generate high-frequency and alternating positive and negative hydraulic shock waves under the ultrasonic vibration action of the grinding tool, the cooling liquid is easier to pump into the grinding area, the updating of the cooling liquid in the grinding area is accelerated, the heat convection capacity of a cooling medium is greatly enhanced, the discharge of fragments is promoted, and the blockage of the grinding tool I-5 is avoided.
As shown in fig. 3(a), when the instantaneous cutting thickness h of the abrasive grains is smaller than the minimum undeformed chip thickness hminMeanwhile, the abrasive particles do not cut into the unprocessed surface material, and only form plowing and sliding effects on the processed surface; as shown in FIGS. 3(b) -3 (c), as h increases, when h > hminWhile the abrasive particles gradually cut into the raw surface, the material gradually undergoes plastic deformation, and residual stress exists at the bottom of the plastic deformation, when h exceeds the minimum undeformed chip thickness hminThe material is plastically sheared to form chips, and the material is plastically removed.
When the abrasive particles cut into the raw surface material, the instantaneous abrasive particle cutting thickness increases from 0, as shown in fig. 3(d), when h increases to a critical value, the final machined surface generates micro-cracks including lateral cracks and median cracks, and the grinding process is changed from plastic domain removal to brittle domain removal; as h progressively decreases, the abrasive particles again drop to 0 as they withdraw from the unprocessed surface material. Therefore, intermittent grinding can be achieved in ultrasonic vibration micro-grinding from the viewpoint of the instantaneous cutting thickness of a single abrasive grain.
Ultrasonic vibration mechanism:
the ultrasonic wave is a vibration wave having an acoustic frequency of 20kHz or more, which does not cause a human auditory reaction. Ultrasonic vibration converts a high-frequency signal sent by an ultrasonic power supply into high-frequency vibration through an energy converter, then the vibration is transmitted to an ultrasonic cutter through an ultrasonic amplitude transformer, and the instantaneous cutting depth of abrasive particles is periodically changed by superposition of axial ultrasonic vibration amplitude.
The maximum undeformed cutting thickness of the abrasive dust and the average thickness of the abrasive dust can be changed through ultrasonic vibration, the material removal rate is improved, and the nano fluid can be more fully infiltrated into the grinding wheel and a workpiece, so that the cooling and lubricating effect and the nano fluid utilization rate are greatly improved, the conversion schematic diagram of the volume of the abrasive dust during grinding is shown in fig. 4, and the related calculation is as follows:
deducing according to the principle of unchanged volume, wherein the maximum thickness of grinding undeformed abrasive dust is as follows:
Figure BDA0003377068310000081
wherein N issThe effective grinding edge number per unit area of the grinding tool; c is the ratio of the width of the abrasive dust to the thickness of the abrasive dust, i.e. C is bg/ag。
Replacing the fish-shaped abrasive dust with a similar rectangular hexahedron
Figure BDA0003377068310000082
In the formula: v0Is each one ofA volume of one abrasive particle; vWIs the volume of workpiece material removed.
Formula (2) can be written as:
Figure BDA0003377068310000083
in the formula:
Figure BDA0003377068310000084
in order to obtain an average width of the abrasive dust,
Figure BDA0003377068310000085
(C is a proportionality coefficient related to the size of the tip angle of the abrasive particles);
Figure BDA0003377068310000086
in order to obtain an average thickness of the abrasive dust,
Figure BDA0003377068310000087
lsthe value of the length of undeformed abrasive dust can be determined by the geometric contact length formula, i.e.
Figure BDA0003377068310000088
And b is the grinding width of the grinding tool.
This is then derived from equation (3):
Figure BDA0003377068310000089
the maximum undeformed chip thickness is then:
Figure BDA00033770683100000810
ultrasonic vibration assisted grinding mechanism:
in the micro-grinding process, the machining mechanism is mainly influenced by the ratio of the radius of the abrasive particles to the thickness of the undeformed chip, and the radius of the abrasive particles and the thickness of the undeformed chip are in the same scale, so that the undeformed chip is cutA small variation in chip thickness will have a large effect on the machining mechanism. The material removal mechanism is different from the traditional machining mode under the combined action of size effect, the principle of minimum chip thickness and the like. Under dynamic impact load, the dynamic fracture toughness of the material is reduced by more than 70 percent relative to the static fracture toughness. Thus, the dynamic fracture toughness K of brittle materials under ultrasonic vibrationIDReplacement of static fracture toughness KICThe calculation is carried out, namely:
KID＝30％KIC (6)
therefore, in the ultrasonic vibration end surface micro-grinding, compared with the traditional end surface micro-grinding, the larger relative speed and acceleration between the abrasive particles and the material are caused by the additional ultrasonic vibration, so that the larger dynamic impact action between the abrasive particles and the material is caused, and the plastic domain grinding is easier to realize under the ultrasonic vibration end surface micro-grinding by considering the dynamic impact action, so that the larger material removal rate can be achieved on the premise of the plastic domain grinding.
According to the indentation fracture mechanics, when the processing load is less than the critical load, the biological bone material is mainly removed in a plastic mode; when the working load is greater than the critical load, it is removed mainly by brittle fracture. Critical load under ultrasonic action FmaxAnd critical cutting thickness hmaxComprises the following steps:
Figure BDA0003377068310000091
Figure BDA0003377068310000092
in the formula: alpha is a geometric coefficient; beta is a constant; hVThe hardness of the biological bone material; kIDDynamic fracture toughness; kv is an influence coefficient with a value larger than 1, and is related to the hardness change of the biological bone material under the action of ultrasound; e is the modulus of elasticity of the bone material. When K isIDIncrease, HVWhen reduced, hard brittle materials tend to transform from brittle to plastic states and vice versa. Thus, inIn the ultrasonic vibration-assisted micro-grinding process, the introduction of ultrasonic vibration has a softening effect on the workpiece material, and the hardness H of the workpiece material is reduced to a certain extentV(ii) a Meanwhile, the introduction of ultrasonic vibration reduces the elastic yield between the grinding tool and the workpiece, so that the processing process is more stable, the dynamic impact action is reduced, and the dynamic fracture toughness K of the material is shownIDThere is an increase. Therefore, as can be seen from equations (7) to (8), the ultrasonic vibration increases the critical load and the critical cutting thickness, which is generally 2 to 3 times as large as that of the ordinary grinding.

Theory of air-floating platform vibration isolation system:
vibration isolation is the direct transfer of vibration to be eliminated or suppressed by placing a suitable vibration isolator between the vibration source and the equipment to be isolated. Each independent degree of freedom of the vibration isolation device can be simplified into a single-degree-of-freedom vibration isolation system, as shown in fig. 12; the controlled object is a rigid mass block, the vibration isolator is a non-mass element formed by connecting an ideal vibration isolator and a damper in parallel, and the foundation is a rigid body with infinite mass.
The vibration differential equation of the single-degree-of-freedom vibration isolation system is as follows:
Figure BDA0003377068310000141
in the formula, m is load mass, k is system stiffness, and c is system damping.
Is provided with
Figure BDA0003377068310000142

order to
x(t)＝X(w)y(t) (12)
Figure BDA0003377068310000151
Wherein X (w) is a foundation vibration transfer function of the system, which characterizes the transfer effect of the system on the vibration transferred to the isolated system object by the foundation through the vibration isolation system. As can be seen from fig. 12, the transfer expressions of the system are the same, and then:
T(w)＝X(w) (14)
the modulus | T (w) | of T (w) refers to the steady-state amplitude transfer of the system under the ground simple harmonic vibration disturbance as follows:

Figure BDA0003377068310000154

where ζ is the damping ratio of the vibration isolation system, f is the vibration frequency of the ground disturbance vibration, and fnIs the undamped natural frequency of the vibration isolation system. The natural frequency refers to the free vibration frequency of the vibration system, and the lower the natural frequency, the longer the free vibration period of the system. From the above, decreaseThe natural frequency of the vibration isolation system and the damping ratio of the system are increased, so that the vibration of the large vibration isolation platform to the ground can be effectively improved.
