3D Scanning in Manufacturing

Quality inspection

At Voxel3D Technology Pvt. Ltd., we ensure that every inspection is performed with the utmost precision, leveraging our advanced 3D scanning technology and laser trackers to meet the highest quality standards. Our process is designed to be efficient, flexible, and non-invasive, ensuring minimal disruption to your operations while providing reliable, real-time data to improve product quality.

Step 1: Initial Consultation & Planning

Before the inspection, we work closely with you to understand the specific quality requirements and the nature of the components to be inspected. This includes: • Identifying key inspection areas based on the component's geometry and functional importance. • Selecting the appropriate inspection technology (3D scanner, laser tracker, or portable arm) based on the size, complexity, and location of the parts. We then create a detailed inspection plan that outlines the process, timeline, and necessary equipment.

Step 2: 3D Scanning Setup

Our team sets up advanced 3D scanning equipment onsite to begin capturing the physical geometry of your components. The 3D scanners we use are highly accurate, capable of measuring with an accuracy up to 20 microns. The scanning process involves: • Capturing a high-density point cloud of the component's surface. This provides a detailed digital model of the part, allowing us to inspect and compare dimensions to the design specifications. • Non-destructive scanning ensures that parts remain unharmed while we gather the necessary data. • Full surface analysis to detect surface defects, deformation, and dimensional inaccuracies. The data collected during scanning is immediately processed to create a detailed 3D model that can be analyzed further.

Step 3: Laser Tracker Inspection

For large or complex parts that require precise measurements over long distances, we use laser trackers. The laser tracker technology measures the exact coordinates of points on the component's surface using a laser beam. Here's how it's applied: • Positioning the laser tracker: The laser tracker is set up around the component and used to measure key points on its surface. It provides micron-level accuracy, making it ideal for large assemblies or critical machinery. • Real-time measurements: As the tracker moves along the component, it collects real-time data, allowing us to identify discrepancies or out-of-tolerance areas quickly. • 3D coordinate system: The laser tracker creates a 3D coordinate system of the component, enabling us to perform a detailed analysis of shape, alignment, and overall dimensional accuracy. Laser trackers are particularly useful for inspecting large-scale components such as wind turbine blades and hydro turbine runners, where traditional methods may be inefficient.

Step 4: Portable Arm Inspection

For parts that require high mobility and flexible inspection capabilities, we employ portable arm coordinate measuring machines (CMMs). These portable arms are ideal for inspecting components directly on the production floor without requiring transportation to a lab. The process includes: • Setup and calibration: The portable arm is calibrated to ensure accurate measurements before inspection begins. • On-the-spot measurement: The arm is moved across the component, measuring various points on the surface. The highly flexible nature of the arm allows access to hard-to-reach areas and complex geometries. • Real-time data feedback: The data is collected and analyzed in real-time, ensuring any design flaws, misalignments, or dimensional deviations are quickly identified and addressed. Portable arm inspection is perfect for inspecting metal parts, molds, and smaller components that require detailed accuracy.

Step 5: Data Analysis & Comparison

Once the scanning and measurement process is complete, we analyze the data to compare the scanned model to the original CAD model or design specifications. This comparison helps us identify: • Dimensional deviations: Any differences between the scanned part and the intended design, such as misalignments, deformations, or manufacturing defects. • Surface imperfections: Detecting issues such as dents, scratches, and uneven surfaces that could impact the functionality or aesthetic quality of the part. • Tolerance verification: Ensuring that the component falls within the specified tolerances and is suitable for further processing or use in assembly.

Step 6: Reporting & Recommendations

Once the inspection is complete, we provide a comprehensive inspection report that includes: • Detailed analysis of the scanned data compared to the original specifications. • Visuals and 3D models highlighting key deviations, defects, or concerns. • Recommendations for improvements, rework, or adjustments to ensure the component meets the necessary quality standards. We also provide manufacturing drawings for any necessary design revisions or parts that need to be modified.
