Introduction:
In the world of CNC machining, precision is key to producing high-quality products with exacting specifications. The detection of precision in tool-tools is a vital step in ensuring that the manufacturing process meets the required standards. In this article, we will explore the various methods used to detect precision in tool-tools, highlighting the significance of accurate measurement and evaluation, and providing guidelines on how to achieve optimal results.
Section 1: Geometric Precision Detection
Geometric precision detection assesses the accuracy of the tool-tool’s geometric shape and position. This is crucial in ensuring that the machine performs as expected, with minimal errors and deviations.
- Rectitude Detection: Utilize a rule, level, or laser interferometer to measure the rectitude of the machine-tool guidance rail.
- Planning Detection: Use a flat plate and a dial counter or a laser interferometer to measure the planning of the workbench.
- Detection of Verticality: Utilize an angle rule and a dial gauge or a laser interferometer to measure the perpendicularity of the pin and the table.
- Detection of Parallelism: Use a dial gauge or a laser interferometer to measure the parallelism between each mobile part.
Section 2: Positioning Precision Detection
Positioning precision detection evaluates the precise positioning capacity of the mobile parts of the tool-tool to designated locations.
- Laser Interferometer Measurement: Use a laser interferometer to measure the positioning error of each axis with a specified position.
- Measuring with a Graphical Rule: Use the network rule and the reading head to measure the positioning accuracy of each axis.
Section 3: Repeated Positioning Precision Detection
Repeated positioning precision detection assesses the repetition of the mobile parts of the tool-tool to reach the same position several times.
- Laser Interferometer Measurement: Use a laser interferometer to measure the positioning error in the same position several times.
- Measuring with a Graphical Rule: Use the network rule and the reading head to measure the positioning error in the same position several times.
Section 4: Machining Precision Detection
Machining precision detection evaluates the overall accuracy of the tool-tool by actually machining a part.
- Test Cutting Method: Utilize standard test parts (e.g., round, square or complex parts) and utilize a three-coordinate measurement machine (CMM) or other precision measurement tools to measure the dimensions and precision of the part.
- Cutting Test: Perform real cutting tests to assess the roughness and dimensional precision of the machining surface.
Section 5: Precision Detection of the Pin
Precision detection of the pin evaluates the precision and rigidity of the rotation of the spindle.
- Radial Jump Detection: Use a dial gauge to measure the radial jump in the spindle.
- Axial Detection of Contractions: Use a dial gauge to measure the axial contraction of the spindle.
- Dynamic Balance Detection: Use a dynamic balance machine to detect the dynamic balance state of the spindle.
Section 6: Precision Detection of the CNC System
Precision detection of the CNC system assesses the control accuracy and stability of the CNC system.
- Servomotor System Response Detection: Use an oscilloscope or special detection equipment to detect the response speed and stability of the Servo system.
- Interpolation Precision Detection: Use a laser interferometer or a club to detect the interpolation accuracy of the CNC system.
Conclusion:
The detection of precision in tool-tools is a complex process that requires a deep understanding of the various methods and tools used. By employing precision measurement tools such as laser interferometers, network scales, dial gauges, and three-coordinate measurement machines, combined with standardized detection methods and environmental control, manufacturers can ensure that their tool-tools meet the required standards, resulting in high-quality products with precise specifications.
