Obtaining data on the geometry of a cutting tool

Machining is still one of the most popular manufacturing process. The tools used for this type of conventional machining are known as “cutting tools”. They usually have different shapes and a short life.

Many companies are creating their own digital archives of cutting tools for the rapid reproduction in the case of run-out or for the modernization to meet the current needs of production.

Despite there are various methods of obtaining information about the geometry of these tools, 3D scanning is the most convenient. It allows to obtain a digital model of a cutting tool, for further redesigning, virtual testing, checking its geometry and features, getting conceptual physical models, or even performing functional prototypes for actual tests.

On request of a production company RangeVision specialists performed 3D scanning of the cutting tool and prepared drawings for its reproduction.

The main goal was to obtain a digital copy of three cutters samples with a maximum precision. Then the dimensions of cutting edges were to be represented as drawings. Digitizing was done with a 3D scanner RangeVision PRO 2M.

To speed up the process of getting initial 3D models, all three cutting mills were scanned together. While performing a 3D scanning of a group of objects, they should be placed at a minimal distance from each other, but without mutual overlapping of their surfaces. Cutters were fixed with clay on the plate with markers. After that the circular scanning was conducted and facet surface of the milling cutters in .STL format was obtained.

Next step was the creation of the mathematical models according to the scan data and verification of constructed models with respect to the original faceted surface. Comparison of the results in a color representation were sent to the client for approval.

Once the customer has agreed this milestone, the drawings with all dimensions required for the production were prepared.

As a result, the client received drawings of the cutting tool and the opportunity to self-reproduce it. Therefore the cost of high-mortality parts was reduced. The company gained independence from foreign suppliers and flexibility in planning of its production cycle.
