Vision Measuring Technology Enables High-Precision Geometric Dimension Inspection for Powder Metallurgy Parts

In the powder metallurgy industry, the geometric dimension accuracy of green compacts (unsintered parts) and sintered finished parts – especially critical parameters like length, width, and position tolerance – significantly impacts product assembly reliability and final performance. However, these parts often present challenges like edge burrs, surface porosity, and low reflectivity, making traditional measurement methods difficult. Sinowon Instruments' high-precision Vision Measuring Machines (VMMs) / Optical Measuring Machines (OMMs) provide an effective solution for these inspection tasks.

Precision Captured: Optical Imaging Tackles Powder Part Measurement Challenges

Sinowon's Vision Measuring Machines (Optical Dimensional Measurement Systems) utilize advanced optical imaging systems and intelligent image processing algorithms to deliver non-contact, high-efficiency, and high-precision Geometric Dimension Measurement for powder-formed metal parts:

• High-Performance Optical System: Equipped with high-resolution industrial cameras and telecentric lenses to minimize perspective errors, ensuring clear imaging of powder metallurgy part contours, including micro-features (e.g., small holes, thin slots).
• Intelligent Multi-Light Illumination: Addresses surface characteristics (like uneven or low reflectivity) with programmable combinations of coaxial, ring, and surface lighting. Suppresses burr interference, enhances feature edge contrast, and supports stable, reliable edge extraction.
• Sub-Pixel Edge Extraction: Applies advanced image processing algorithms for sub-pixel edge detection, improving the repeatability and accuracy of dimensional measurements, effectively handling minor burrs or porosity on part edges.
• Non-Contact & Non-Destructive Measurement: Eliminates the risk of green compact deformation or sintered part surface damage associated with contact methods, ensuring safe inspection.

Core Geometric Dimension Measurement Applications

Sinowon Vision Measuring Systems are ideal for inspecting key dimensions of powder metallurgy parts:

• Length & Width Measurement:

• Precise Contour Capture: Automatically identifies and measures overall part length and width. Intelligent algorithms assist in datum determination, even with minor burrs or irregular edges.
• Local Feature Dimensions: Accurately measures the length/width of local structures like bosses, grooves, and ribs to verify compliance with design tolerances.

• Position Tolerance Precision Measurement:
• Hole & Feature Location: High-precision positioning of multiple mounting hole/pin hole centers. Calculates position tolerance error relative to datums (e.g., centerlines, edges), critical for ensuring part assembly accuracy.
• Feature-to-Feature Relationships: Measures positional relationships like distance and angular offset between features (e.g., multiple bosses) on different planes or angles.
• Contour & Form Analysis:

• Utilizes contour scanning to capture edge profile data for comparison against CAD models, evaluating profile tolerance.
• Measures form tolerances (roundness, cylindricity, straightness) for comprehensive geometric quality assessment.

Efficiency & Intelligence Combined

• Batch Inspection Capability: Combined with CNC auto-programming and custom fixtures, enables rapid automated measurement of multiple parts per batch, boosting QC efficiency.
• Professional Software Analysis: Sinowon measurement software offers an intuitive interface, comprehensive Geometric Dimension evaluation tools (GD&T), and SPC statistical analysis. Generates professional inspection reports for process optimization data support.
• Data Traceability: Complete recording of measurement processes and results meets quality management system requirements for traceability.
