Holon 3D engineers can use the 3D scanner HL-3DW to perform full-scale analysis on the surface of the ship's engine, and finally generate a detailed inspection report. Any position deviation can also be displayed numerically.

Practical problems

1. The size of the ship engine shell is 2m*0.8m*1m, and there are many curved surfaces and assembly positions. In addition to improving the measurement efficiency and greatly shortening the measurement time, the measurement accuracy must also be well controlled. The global measurement accuracy is required to be controlled at 0.1mm Within
2. The amount of data obtained by traditional measurement methods for ship engine shells is insufficient, and it is impossible to carry out secondary design and product quality inspection.

Holon solutions

A well-known foundry company is a relatively experienced company in the large-scale casting industry. The traditional measurement method of the engine is to use three-coordinates to manually mark the lines, and the three-coordinates use the contact measurement method. The measurement efficiency is very low, it takes about a week, and the accuracy is not high. About 1.5mm, the efficiency is low, the effect is poor, and it is not suitable for the rapid development trend of the market.

On-site scanning of ship engines

The shell size of the ship engine is 2m*0.8m*1m, and there are many curved surfaces. The customer mainly inspects the processing size, assembly position, and hole position. In addition to improving the measurement efficiency, greatly shortening the measurement time, the measurement accuracy must also be well controlled. The global measurement accuracy is controlled within 0.1mm. After understanding his actual situation, we use the three-dimensional scanner HL-3DW. The entire scanning process takes about 3 hours with an accuracy of 0.1mm, which completely exceeds the company’s expected scanning completion time in 1 day. . Shorten the cycle, reduce costs, reduce risks, improve quality, and enhance corporate competitiveness.

Ship engine STL data

Import the acquired three-dimensional data of the ship engine into the inspection software Geomagic Qualify, which can quickly detect the difference between the Mercedes-Benz turbine blade (CAD) model and the manufactured parts of the product. Geomagic Qualify can display the two with intuitive and easy-to-understand graphical comparison results. The difference.
