Description

Technical Field

[0001] This application relates to the field of electrical discharge machining, and in particular to an automatic control method, apparatus, equipment and medium for side discharge electrodes. Background Technology

[0002] Currently, when using electrical discharge machining (EDM) to process molds, side discharge is sometimes required to improve processing efficiency and accuracy. However, in related technologies, the side discharge electrode requires a significant amount of manual intervention before processing. For example, it is necessary to consider the eccentricity of the electrode relative to the fixture during coordinate measuring machine (CMM) measurement, the eccentricity of the fixture itself, and the conversion of data for the length, width, and height of the fixture when performing side discharge in different orientations. This process is usually done manually, which is tedious. Furthermore, manually calculating the relative positions of points in three-dimensional space requires a high level of experience from the technicians. If the final eccentricity value is calculated incorrectly, the processed workpiece will not meet the accuracy requirements, and in severe cases, the target workpiece may be scrapped. Summary of the Invention

[0012] Based on the second eccentricity value, a first discharge procedure for the side discharge electrode is generated.

[0013] By adopting the above technical solution, the desired discharge posture of the target electrode relative to the workpiece, i.e. the first discharge state, can be obtained from the first discharge parameters. The parameters such as the first discharge coordinates, the first discharge orientation, the first discharge matrix, and the first C-angle quadrant value can comprehensively represent the relative position between the electrode and the target workpiece.

[0014] By measuring the parameters, the observed discharge attitude of the target electrode relative to the workpiece, i.e. the second discharge state, can be obtained. After calculating the first eccentricity value based on the second discharge state, it can be determined whether the target electrode is qualified. Only qualified electrodes will be automatically controlled in the subsequent process.

[0015] Based on the first change relationship, the relationship between the set relative positional relationship between the electrode and the target workpiece and the measured relative positional relationship between the electrode and the target workpiece can be obtained.

[0055] Figure 3 This is a third flowchart illustrating an embodiment of an automatic control method for side discharge electrodes in this application. Detailed Implementation

[0056] The following combination Figures 1-3 This application will be described in further detail below.

[0057] Reference Figure 1 An embodiment of an automatic control method for a side discharge electrode includes the following steps:

[0058] S101. Collect the first discharge parameters when the side discharge electrode discharges. The first discharge parameters include the first discharge coordinates, the first discharge orientation, the first discharge matrix, the first C-angle quadrant value, and the spark position.

[0059] Among them, discharge coordinates refer to the position coordinates of the discharge point, including coordinate values ​​of the X, Y, and Z axes, used to determine the specific position of the discharge point on the workpiece. These coordinate values ​​are calculated by the CNC system or other control equipment based on the machining drawings or CAD models, and are used to accurately locate and control the discharge position of the electrode on the workpiece surface. Discharge orientation usually refers to the relative position and orientation of the discharge electrode and the workpiece surface. The distance between the discharge electrode and the workpiece surface is an important factor in determining whether the discharge machining can proceed normally. The angle between the discharge electrode and the workpiece surface also affects the discharge effect, and the discharge direction during discharge also affects the machining effect. Matrix value refers to the series of discharge points formed by controlling the discharge position between the electrode and the workpiece during the machining process, thereby realizing the removal and machining of workpiece material. The discharge matrix can be used to describe the movement trajectory of the electrode on the machining surface and the distribution of discharge. C-angle refers to the angle between the discharge angle on the electrode and the electrode axis. According to the size of the angle, C... The angular quadrant is divided into four quadrants, and the angles dividing the four quadrants are the same as those dividing the four quadrants in the rectangular coordinate system. The set and measured values ​​of the electrode's C-angle and the C-angle quadrant are very important in electrical discharge machining (EDM), as they can be used to control the discharge angle and position, thereby achieving precise machining. In EDM, the spark position refers to the actual discharge position between the electrode and the workpiece during discharge. Controlling the accuracy of the spark position is crucial for machining quality and precision.

[0060] Using this embodiment, the desired discharge posture of the target electrode relative to the workpiece, i.e., the first discharge state, can be obtained from the first discharge parameters. The parameters such as the first discharge coordinates, the first discharge orientation, the first discharge matrix, and the first C-angle quadrant value can comprehensively represent the relative position between the electrode and the target workpiece. By adding the spark position to the parameters, the side electrode can be accurately controlled to process the workpiece after the position of the side electrode is determined, in combination with the spark position.

[0061] S102. Calculate the first discharge state when the side discharge electrode discharges based on the first discharge parameters.

[0062] Among them, reference Figure 2 The steps for calculating the first discharge state during discharge by the side discharge electrode include:

[0063] S1021. Obtain the first reference plane of the side discharge electrode and create a first Z vector perpendicular to the first reference plane;

[0064] S1022. Obtain the X-axis of the EDM machine corresponding to the side discharge electrode and create the first X vector;

[0065] S1023. Calculate the first Y vector of the side discharge electrode based on the first Z vector and the first X vector;

[0066] S1024. Calculate the value of the first matrix based on the first X vector, the first Y vector, and the first Z vector;

[0067] S1025. Calculate the first discharge state based on the first matrix value and the first C-angle quadrant value;

[0068] Using this embodiment, the uniqueness of the desired discharge posture of the target side discharge electrode can be determined. It should be noted that the direction of the Y vector is the processing direction of the side discharge electrode. Each electrode has a unique C angle, and the C angle is located in one of the four quadrants relative to the center of the electrode. The uniqueness of the discharge posture of the target side discharge electrode can be determined by the electrode axis represented by the Y vector and the electrode axis represented by the C angle.

[0069] The matrix value of an electrode typically refers to the method of representing the electrode's discharge orientation. This representation method is commonly used in multi-axis CNC electrical discharge machining tools to describe the rotational attitude of the electrode relative to the workpiece. Generally, the discharge orientation of the electrode can be represented by Euler angles or quaternions. In both of these methods, the matrix value can be used to calculate the specific discharge orientation of the electrode. In this embodiment, the first matrix value represents the matrix value calculated from the expected values ​​of each reference. The first X vector, the first Y vector, and the first Z vector are all preset expected values.

[0070] S103. Acquire measurement parameters and calculate the first eccentricity value. Specifically, acquire the measurement parameters when measuring the side discharge electrode and filter the measurement parameters. Calculate the first eccentricity value of the side discharge electrode based on the measurement parameters. The measurement parameters include the second discharge matrix and the second C-angle quadrant value.

[0071] By using this embodiment, filtering the measurement parameters can reduce the measurement error generated when measuring the position of the side discharge electrode, thereby further improving the processing accuracy. Through the measurement parameters, the observed discharge posture of the target electrode relative to the workpiece, i.e., the second discharge state, can be obtained. After calculating the first eccentricity value based on the second discharge state, it can be determined whether the target electrode is qualified. Only qualified electrodes will be automatically controlled in the subsequent process. According to the actual situation, an appropriate tolerance range can be set to determine whether the electrode is qualified. The first eccentricity value is the eccentricity value of the target side discharge electrode itself.

[0072] S104. Calculate the second discharge state during the side discharge electrode measurement based on the measurement parameters;

[0073] Among them, reference Figure 3 The steps for calculating the second discharge state during side discharge electrode measurement include:

[0078] S1045. Calculate the second discharge state based on the second matrix value and the second C-angle quadrant value;

[0079] By using this embodiment, the uniqueness of the target electrode discharge attitude measurement value observed by the measuring device can be determined. The parameters such as the second X vector and the second Z vector are all corresponding measurement values. Then, the second matrix value calculated from the measurement value is obtained to determine the second discharge state, that is, the actual discharge state.

[0080] S105. Calculate the first change relationship based on the first discharge state and the second discharge state;

[0081] By using this embodiment, based on the first change relationship, the change relationship between the set relative positional relationship between the electrode and the target workpiece and the measured relative positional relationship between the electrode and the target workpiece can be obtained.

[0082] S106. Calculate the second eccentricity value of the side discharge electrode based on the first eccentricity value and the first change relationship;

[0083] In this embodiment, a second eccentricity value is obtained after correction based on the measured first eccentricity value, so as to further adjust the discharge parameter setting value of the side discharge electrode. The second eccentricity value refers to the eccentricity value of each expected value of the side discharge electrode relative to the actual measured value.

[0084] S107. Generate the first discharge procedure for the side discharge electrode based on the second eccentricity value.

[0085] Using this implementation method, a first discharge program is automatically generated, which can initially realize the automatic control of the side discharge electrode to perform side discharge processing on the workpiece.

[0090] S1010. Calculate the third eccentricity value of the fixture based on the first clamping state, the second clamping state, and the first change relationship.

[0091] Using this embodiment, a compensation value for the relative positional relationship between the fixture and the workpiece can be obtained. The third eccentricity value is the eccentricity value of each expected value of the side discharge electrode relative to the actual measured value after taking into account the measurement error value of the fixture.

[0092] S1011. Update the first discharge program according to the third eccentricity value to obtain the second discharge program;

[0093] This implementation method compensates for the deviation between the set value and the measured value of the fixture, thereby further improving the machining accuracy.

[0094] In summary, the beneficial effects of the implementation method of the automatic control method for side discharge electrodes in this application include not only:

[0095] The desired discharge attitude of the target electrode relative to the workpiece, i.e. the first discharge state, can be obtained from the first discharge parameters.
