1. Development of 3D Scanning Technologies by Digital Fringe Projection and Laser Scanning technologies

CMTI has experience in developing 3D scanners working on Digital Fringe Projection (DFP) and laser scanning technologies. The fringe projection based scanning technology is able to 3D scan the components to an accuracy of 30 µm. It is a tripod mounted scanner with various options for view combining like marker based, optical tracker (Developed by CMTI) based, robot mounted etc. The laser based scanner developed in-house is designed for hand-held laser scanning. The device is capable of 3D scanning of intricate features by easily manoeuvring the device over the object and is suitable for dark components scanning. These 3D scanners generate 3D model of a given component which is used in applications like 3D measurements, design evaluation, reverse engineering etc. 3D measurement technologies are highly in demand from industries and in various application domains.

2. SolVIS: The AI Based Solar Panel Inspection Software

SolVIS is an inspection software for carrying out automated quality check on pre-captured EL images of onocrystallineand polycrystalline solar panel thereby providing characterization, reducing human error and stress and increasing efficiency of inspection.

Following are the distinctive features of the system:

•  Defect detection and location marking.
•  Defect characterization based on length and area.
•  User defined dynamic inspection criteria.
•  Inspection report with detailed defect statistics.
•  Cycle time of 4 Secs/ panel.
•  Option to train new panels.

3. Thread measurement system

• Non-contact and improved method of external thread form parameter measurement to check for dimensional tolerances.
• High speed thread parameter measurement system which can be used for automating the thread measurement process in the thread manufacturing lines.
• User friendly thread measurement system requiring minimum human intervention.
• Records measurement results for statistical analysis.

3. Fluted Roller Vision Inspection system for defects.

• The system is a vision based inspection system designed to inspect the fluted roller, used in textile machinery, for presence of chip-out and damages at before plating stage.
• The fluted roller vision inspection system consists of two sets of inspection units each unit consisting of a machine vision camera, optics and light sources.
• There are 8 variants in this component with variations in roller length, roller diameter, flute length and flute pitch.
• Various challenges like presence of oil on surface of the sample, reflective surface and variations in sizes and appearance are addressed in this project.
• The software has features like auto inspection cycle, manual inspection cycle, excel reporting eature, summary analysis report, model type detection, wrong loading detection in addition to the defect inspection feature.

4. Optical Tool Setter for USUPTM

• Optical tool setter is an accessory developed for performing the initial tool setting operation in the ultra precision turning machine, developed by CMTI. The system significantly reduce the tool setting time and also simplifies the process by providing accurate measurements of the tool tip offset and the tool nose radius.

5. Automated inspection of surgical screw

• The system is a non-contact inspection solution using machine
  vision for Surgical Screws or Bone Screws. The inspection involves critical
  dimensional measurement with very high accuracy for various parameters to be
  inspected with different sizes and types of screws.

6. Automated inspection of drippers

• The system is a non-contact system for inspection of drippers.
  Drippers are used in irrigation system. Different types of defects like hole blockage, flash on root and collar, cut on collar, short moulding and circularity of the drippers are inspected in this system.

7. Automated inspection of retaining bush.

• “Retaining bush” is a safety critical automotive plastic injection mould component.
• Able to identify all types of defects encountered in the component an inspection stations with 2 cameras
• Inspection rate of 3 components / sec
• Inspection also includes key dimensional measurements
• Automated Component feeding using a vibratory feeder.
