What is the transcript and what is the workflow of Shenzhen prototype factory?

The traditional copying method is to make a prototype model with an equal ratio of one to one by using a stereo engraving machine or a hydraulic three-dimensional modeling milling machine, and then mass production. This method is called analogy (Dialog type) Copying, the workpiece size drawing file cannot be established, and no shape modification can be made. It has gradually been replaced by a new digital copying engineering system.

copying is an accurate and high-speed scanning of existing samples or models by high-speed 3D laser copying machine to obtain its 3D contour data and reconstruct it with the copying software, on-Line accuracy analysis and evaluation of the reconstructed surface are carried out to evaluate the construction effect, and finally IGES or STL data are generated, thus rapid prototyping or CNC machining can be carried out.

copying is usually performed in a project-like manner for a model's imitation work. Often the products to be made do not have the original design drawing file, but entrust the unit to deliver a sample or model, such as wooden shoe mold, golf ball head, toy, electrical shell structure, etc. , please copy the production unit (Copy)Come out. IGES data can be passed to a general CAD system (Such as UG, PRO-E)Further modification and redesign.

In addition, it can also be passed to some CAM systems to set the tool path and generate numerical control code, which will be processed by the CNC machine tool. After STL data is processed by surface fault, the entity is directly produced by laser rapid prototyping
