The M3 Hybrid successfully integrates M3 measurement software, a contact probe sensor, and our non-contact optical sensor (OPTISCAN) to simplify the acquisition of point clouds and measurements of the target object.
Quality control, inspection, in-flight certification, reverse engineering, and 3D modeling are possible! We also support measurements brought to the manufacturing site.
Showa Seisakusho manufactures various types of casting wooden molds, models, and wooden products, enabling consistent high-precision manufacturing from product data creation and processing to inspection. As a company engaged in manufacturing, we can hold discussions from the product launch stage. Using the ROMER Absolute Arm, we can measure and scan not only metal and aluminum materials but also dark and glossy items. Additionally, we can stably measure and scan complex shapes and soft parts made of materials like urethane and sponge. 【Features】 ■ Measurement through contact and non-contact methods ■ Ability to scan various materials non-contact ■ Measurement and scanning possible for dark and glossy items in addition to metal and aluminum materials ■ Portable, allowing for on-site measurements in manufacturing environments ■ Measurement results expressed as point clouds and color maps ■ Arm length of 1.5m, capable of measuring up to a maximum range of 3m * Measurements over 3m can be accommodated upon request ● For more details, please contact us or download the catalog.
![[Example] High-Precision Reverse Engineering (Simple Shape Work)](https://image.mono.ipros.com/public/product/image/4f8/2000513756/IPROS43364548402808302345.jpeg?w=280&h=280)
We will introduce a method for reverse engineering simple-shaped workpieces with higher precision.
Commonly used methods for obtaining point cloud data for reverse engineering include 3D laser scanners and X-ray CT devices. However, regardless of how precise the equipment used is, an error of approximately ±0.05 to 0.1 mm occurs during data acquisition. Since the scan data is based on these initial errors, it can be said that achieving highly reproducible reverse engineering is nearly impossible. To improve reproducibility, there are methods to correct CAD drawings by incorporating actual measurements using calipers or micrometers, but there are limitations to the shapes and dimensional accuracy that can be measured with small tools. Our company has been providing measurement services using high-precision measuring instruments such as three-dimensional measuring machines and shape measuring machines for many years, enabling us to perform high-precision reverse engineering leveraging our advanced measurement technology. In this blog, we will introduce high-precision reverse engineering methods for simple-shaped workpieces.
![[Case Study] Comparison of Scanning Accuracy between 3D Laser Scanners and X-ray CT Devices](https://image.mono.ipros.com/public/product/image/ef7/2000513779/IPROS74824299017178898123.jpeg?w=280&h=280)
I will introduce a comparison of the scanning accuracy between 3D laser scanners and X-ray CT devices.
When performing reverse engineering, it is necessary to obtain point cloud data of the sample's shape, and the major methods for data acquisition are 3D laser scanning and X-ray CT scanning. Each method has its advantages and disadvantages, but which scanning method offers better accuracy (i.e., higher shape reproducibility)? In this case, we will verify the extent of error and distortion in the scan data from the 3D laser scanner and the X-ray CT scanner based on the dimensions measured by a three-dimensional measuring machine. The procedure is as follows: 【Step 1】 Obtain point cloud data of the sample's shape using a 3D laser scanner. 【Step 2】 Obtain point cloud data of the sample's shape using an X-ray CT scanner. 【Step 3】 Conduct dimensional measurements using a three-dimensional measuring machine. 【Step 4】 Extract dimensional data from the point cloud data in Steps 1 and 2, and compare it with the dimensional data from Step 3.
