The location dimension between 3 sheet resistance foil gauges 8 on individual face, substrate and the grid silk of resistance strain gage 8 are towards the length side of handle of a knife 6
To, same group of resistance strain gage 8 according to the force analysis distribution of results of handle of a knife 6 in the surface stress symmetric position of handle of a knife 6, Suo You electricity
The initial resistivity value of resistance foil gauge 8 is other three fixed value resistances of use in R, Z-direction measuring circuit, each fixed value resistance

Described resistance strain gage 8 is combined into three groups of wheatstone measurement bridges, each group of measuring bridge using electronic compensating method
The independent measurement of the D cutting operations force component of respective direction can be realized, concrete principle is：1. when Z-direction cutting force acts on car
During knife, compression occurs for handle of a knife 6, is understood that on the surface of handle of a knife 6 compression will be produced according to mechanics of materials general principle, due to each
Resistance strain gage 8 is identical in resistance change in stress symmetric position, therefore each measuring bridge in individual measuring bridge, Z side
Output is produced because bridge arm change in resistance is uneven to the measuring bridge of cutting component, and X and Y-direction cut the measurement of component
Electric bridge remains in that balance, will not produce output；2. when Y-direction cutting force acts on lathe tool, handle of a knife 6 occurs bending and deformation,
Understand that resistance R10 and R11 is influenceed resistance value to increase Δ r by tension in Y-direction measuring circuit according to material mechanics principle, and
Resistance R7 and R8 is influenceed resistance value to reduce Δ r by compression, causes Y-direction measuring bridge to produce output, such as formula (1) institute
Show；And now, resistance R1, R2, R4, R5 are due to symmetrical in X-direction measuring bridge, and R2 and R4 are by compression shadow
Ring resistance value reduction Δ r, R1 and R5 is influenceed resistance value to increase Δ r by tension, and measuring bridge does not produce signal output, such as public
Shown in formula (2)；Resistance R9 compression chords influence resistance value reduces Δ r, the influence of resistance R12 tension stress in Z-direction measuring bridge
Resistance value increases Δ r, and resistance R3 and R6 are located on neutral line, and resistance value does not change, therefore bridge arm total resistance value does not change,
Z-direction measuring bridge will not produce signal output；3. similarly, it can analyze and obtain：When X-direction cutting force acts on lathe tool, X side
Signal output is produced to measuring bridge, and Y and Z-direction measuring bridge will not produce signal output；Therefore above-mentioned three groups of favour stones
Measuring bridge can realize the independent measurement of D cutting operations force component without being influenceed by other direction cutting force, meet three
The requirement of dimension cutting force component decoupling measurement.
Described Signal Pretreatment is first order signal processing unit with collecting device 12, be responsible for acceleration transducer and
The output signal of wheatstone measurement bridge carries out tentatively amplification, filtering, A/D conversions, signal acquisition.
Described master system 13 is responsible for depositing the acceleration signal and wheatstone measurement bridge signal that collect
Storage, computing and display.
The present invention operation principle be：In cutting process, when cutting force acts on blade 3, in edge bearing 4
The three shaft vibration acceleration transducers 5 in portion measure the vibration acceleration of cutter overhanging part and output as caused by high frequency cutting force
The acceleration signal in tri- directions of X, Y and Z；The resistance strain gage 8 being packaged in the groove 7 with the level of knife bar front end is respectively constituted
Three groups of measuring bridges are used for the low frequency Cutting Force Signal for measuring tri- directions of X, Y and Z；All acceleration signal and low frequency cutting force
Signal is amplified, filtered and gathered with collecting device 12 by Cutting Force Signal pretreatment, and is transferred to master system 13
It is upper to be handled, shown and stored；The signal of all directions is according to F after processingi=Fi1+Fi0Carry out geometry addition and obtain final
Cutting Force Signal, wherein i represent tri- directions of X, Y and Z, F respectivelyiFor X, Y and the cutting force of Z-direction, Fi1For X, Y and Z-direction
High frequency cutting force, Fi0For X, Y and the low frequency cutting force of Z-direction.
In reference picture 4, actual cut process, Cutting Force Signal is made up of the signal of different frequency composition, tool
Body, which is divided into low-frequency component and radio-frequency component, broadband cutting force measurement device of the present invention, uses wheatstone measurement bridge and three
Shaft vibration acceleration transducer 5 realizes the measurement to low frequency and radio-frequency component in Cutting Force Signal respectively.Wherein, cutting force is believed
Low-frequency component in number causes handle of a knife 6 to bend or compression, and the deformation is glued to the surface of handle of a knife 6 groove with the level
Resistance strain gage 8 in 7 perceives and is converted to electric signal corresponding with low frequency Cutting Force Signal by measuring bridge；Cutting force is believed
Radio-frequency component in number causes cutting tool overhanging part to produce forced vibration, is analyzed by taking X-direction cutting force component as an example,
By cutter overhang part in X direction cutting force radio-frequency component effect under motion model be reduced to one containing mass m,
Spring k and damping c second order single-freedom vibration system, as shown in figure 5, according to Newton's second law, the differential side of the system
Journey can be expressed as：
In formula (3)：--- the acceleration that measurement apparatus overhangs partly in X direction；--- measurement apparatus overhanging part
Speed in X direction；The displacement that x --- measurement apparatus overhangs partly in X direction；FX--- X-direction cuts force component.Pass through three
The measurement of shaft vibration acceleration transducer 5 obtains the vibration acceleration of cutter overhanging part, and further obtains cutter by integration
The speed of overhanging part and displacement, the radio-frequency component in Cutting Force Signal can be obtained by bringing formula (3) into.
Due to the Cutting Force Signal low frequency obtained by wheatstone measurement bridge and the measurement of three shaft vibration acceleration transducers 5
Without clearly into the low-frequency component and three axles of boundary, the i.e. measurement of resistance strain gage bridge circuit between radio-frequency component signal
The repeating signal of identical frequency content is there may be between the radio-frequency component that the measurement of vibration acceleration sensor 5 is obtained, therefore not
The signal that simply two parts measurement can be obtained directly is added, and needs to be filtered signal processing before this to eliminate two
Repeating part in sub-signal.Filtering is carried out in master system 13, and the output signal progress to wheatstone measurement bridge is low
Pass filter, high-pass filtering, unidirectional Cutting Force Signal low pass and high-pass filtering cut-off frequency phase are carried out to acceleration signal
Together, the Cutting Force Signal filter cutoff frequency of different directions can be different.By taking X-direction Cutting Force Signal filtering process as an example, if
X-direction wheatstone measurement bridge low pass signal filter cutoff frequency is put for fx, reserve frequency is less than fx signal；Acceleration signal
High-pass filtering cut-off frequency is fx, and reserve frequency is greater than or equal to fx signal.If the low frequency cutting force obtained after filtering process
Signal is FX0, acceleration signal isIt is F to be calculated according to formula (3) and obtain high frequency Cutting Force SignalX1, then the cutting force of X-direction
Signal is FX=FX0+FX1.Y and the Cutting Force Signal of Z-direction also take above-mentioned processing method, repeat no more.
Master system 13 shows X, Y and the Cutting Force Signal of Z-direction after processing in software interface in real time, for upper
All signals before and after treatment for stating all directions referred to are stored in master system 13, in case inquiry,
Call and other research purposes.
