Compensation and compensation related parameters and description Machine reference point and backlash direction and the first axis are set to the direction of the reference point return when the power is turned on and the initial backlash compensation direction is set. The reference point return direction and the backlash compensation direction are positive. The direction reference point return direction and the backlash compensation direction are negative directions.
The pitch ratio of the numerical control system and the pitch error compensation magnification are used in all axes. The true value of the error compensation ratio is the system. The compensation parameter is compared with the system. The reference steam and the pitch ratio are the same as the floating-point error. Han replenished the amount of Huizhenzheng limited knife month, the beginning of the movement of the buddy] Shen Yi led the levy to shake the continent 《 《 洲 洲 洲 洲 洲 洲 洲 洲 洲 洲 洲 洲 洲 洲 洲 洲 洲 洲 洲 洲 洲 洲 洲 洲 洲 洲 洲 洲 洲, backlash compensation amount, setting range.
one. The system compensates zero point and pitch error compensation zero point, setting range one.
When the compensation interval and pitch error of the system are compensated, the distance between the two set points, that is, the interval of the pitch error compensation point, the minimum value and the maximum feed rate.
Maximum compensation stroke compensation interval test.
The pitch error compensation amount, that is, the parameters of each symplectic feed point, the set value and the soil system compensation parameters.
Measurement method and determination of compensation data The value of the backlash compensation parameter is measured using a dial gauge.
Clamp the dial gauge to a position fixed relative to the bed, move the shaft to be measured, and squeeze the shaft to zero.
The control system position display is cleared.
Use the jog to move the measured axis in the opposite direction until the dial gauge pointer changes.
At this time, the amount of displacement displayed by the control system minus the amount of pointer fluctuation is the screw gear clearance of the shaft.
Measured with a dual-frequency laser interferometer.
The absolute value of the data difference between the forward measurement data curve and the reverse measurement curve at the commutation is the screw tooth gap of the axis.
When the gap value reaches a certain value, check if the screw connection nut is loose.
Technical communication should be measured in the new tube as follows.
May be turned on, and should be reversed.
Since the turn-on voltage of the FET is generally susceptible to damage due to the gate of the FET, it should generally be between and the gate-source breakdown voltage is around, so the measuring tube is stored in a dedicated anti-static package. .
When accessing, the user should first touch the multimeter of the battery to use the pointer multimeter.
Guide the ground wire and discharge the static electricity on the handle to prevent static electricity from damaging the pipe.
In addition, the red pen is connected to the pole and the black pen is connected to the pole. When the pipe is touched, the source should be touched first and then the gate.
If there are conditions, the resistance between them should be large.
At the same time, the capacitor is charged in the forward direction, and the tube can be taken with an anti-static glove.
When soldering, the gate source should be turned on first with a wire.
At this time, the red pen is connected, the black pen is connected, and the multimeter is short-circuited. The electric iron should be well grounded or the electric plug of the electric iron should be unplugged. The indication value should be close, indicating that the conduction is normal.
The reverse turn-off measurement first uses residual heat welding to avoid breakdown of the tube.
The red test leads are connected to the poles, and the black test leads are connected to the poles. After that, the input capacitors are reversely charged to one and remain.
Secondly, the red test pen is connected to the pole, the black test pen is connected to the pole, and the resistance between the poles should be very large, indicating that the pipe is turned off. If the multimeter's test pen is reversed, there is a protection diode between them, and the compensation interval is the pitch error compensation parameter value. The methods used to measure the pitch error are block gauge measurement, step gauge measurement, optical reader measurement, and dual-frequency laser interferometer measurement.
Each unit can choose according to the actual situation.
The axis of the homing measured by the measurement method determines the error compensation origin.
Clear the measurement instrument table and control system display position data.
After compiling and running the automatic start-stop cycle program function, after running the compensation interval distance, stop the time enough to read the data, run it again, and then return to the measurement and record.
Repeat the measurement two or three times.
The data record table and the number of processing records and processing methods are shown in the table.
The parameter compensation method records and repeatedly checks all parameters of the system before compensation.
Set the following parameter setting method. General information has a description of the reference point return direction, the initial backlash compensation direction.
Pitch error compensation magnification.
The pitch error compensates for zero.
Pitch error compensation interval.
After shutting down and returning to the machine origin, take measurements.
Set the measured pitch error compensation amount and backlash compensation amount.
