Reverse Engineering Software Using the Non-Contact Measurement Data

spScan is a reverse engineering software to create a NURBS surface from the non-contact measurement data.

A surface with the available quality in CAD/CAM/CAE, can be created in a short period of time (including automatic processing).

spScan

Purpose

Mold Measurement & Reverse
1. Create a master data for mass production.
Create a CAD mold data from the mold measurement data (partial reverse)

2. Create a Copy mold data.

Product Measurement & Reverse
1. Analysis and CAD feedback of prototype product.
- Creating simple surface for design such as interference (Fitting) etc.
- Various simulation such as strength/vibration/fluid

2. Data creation of coincident product (past product).

3. Other company’s products (functional products) analysis.

Characteristic

spScan

1. High-quality surface definition in order to connect to the machining
2. Fitting accuracy to the measurement data
3. Surface boundary curves that can be edited in the CAD/CAM/CAE
4. Lightweight data size (optimal order and number of patches)
5. Free divided surface (supporting for trimmed surface)
6. Automatic processing

Reverse Technique Variation

spScan

Four methods of Surface creation will be provided.
It can be selected in consideration of the usage and the working man- hours.

Basic Processing Flow

spScan

Point Cloud Import/Polygon Mesh Creation

Import the measurement point cloud and create polygon mesh.
When creating Polygon Mesh, in accordance with the specified accuracy, perform thin-out, fill- hole and smoothing at the same time.

Supported format ASCII, STL, SWL, AC, etc.

Polygon Mesh Edit

Edit Polygon Mesh created from point cloud in accordance with reverse purpose.

spScan

Reduce the number of vertices of the Polygon Mesh.

spScan

Remove the Polygon Mesh on each island.

spScan

Remove the part of the Polygon Mesh.

spScan

Fill the holes in the Polygon Mesh.

spScan

Fill in the concave portion of the Polygon Mesh.

spScan

Do the smoothing of the Polygon Mesh.

spScan

Modify the overlapped area of the Polygon Mesh.

CAD Data Import

spScan is possible to reverse by point cloud only.
In case there is a CAD data to reverse the target work, spScan is enable to partial reverse. Use CAD data as reference data for reverse area. The area that does not required to reverse can be used as a copy data for other area.
Supported data format is IGES and STEP data.

Alignment (spAlign)

Point Cloud data and CAD data must be aligned, in case Point Cloud data and the CAD data are represented in different coordinate systems. Coordinate Alignment can be divided into 2 large divisions as follows.

Alignment Function 1. Align with constraint on specific element, such as hole, plane, cylinder, etc.
2. Align by minimizing the error sum between Point Cloud and CAD data.

Group Automatic Creation/ Editing

By calculating the curvature of the polygon shape, do the automatic grouping (surface configuration definition) It is possible to change from the outside the curvature radius to be used for grouping.

Create Curve/ Editing

Automatically creates a boundary curve as a CAD data from the boundary line of the polygon curvature group. Do the re-division of the surface and the curve editing in accordance with reverse purpose.

spScan

Create a smooth curve from such as polyline.

spScan

Approximates the curve to circular arc.

spScan

Creation and editing of the free curve

Create/Edit Surface

It is possible to create a surface automatically or manually from the boundary curves and the point cloud. In the case of automatic creation, the system will automatically determine the bounded surface and the trimmed surface.
It is possible to specify the type of base surface such as plane, cylinder, free surface, etc.

spScan

Create a fillet surface.

spScan

Adjust the curve of blended part and create a surface.

spScan

Create a sharp edge between surfaces.

spScan

Specify radius and create a fillet surface.

spScan

Create a primitive surface.

spScan

In case that do not care about the surface quality (configuration), the configured surface group by net pattern with the four sides patch will be automatically created.

Partial Reverse

By using the CAD data, only the area with error between Polygon Mesh and surface can quickly and easily be created.
There is surface fit and surface optimization in the partial reverse function.

spScan

Partial Reverse
Remove only the surface of the modification part, and create a partial surface while keeping continuity with the surroundings.

spScan

Optimize Surface
Optimize surface to minimize the error of the polygon.

Reversed Surface Evaluation

It can be evaluated whether the reversed surface suits the purpose.
Polygon error-color-map, error between surfaces, angle between surfaces, zebra map, etc. are prepared as the main evaluation function.

spScan

Display the error between Surfaces and Polygon Mesh by Color Map.

spScan

Display the distance between surfaces.

spScan

Display the angle between surfaces.

spScan

Display surfaces by Zebra Mapping. By the zebra display, check the surface status and connection between surfaces.
