Welcome one more day to the blog of Mecánica Curiel, your mechanized company in Barcelona. In the new entry today we want to talk about rapid prototyping by cnc machining.
What is CNC machining prototyping?
It is a rapid prototyping technique by machining to manufacture prototypes with additive manufacturing technologies, that is, 3D printing. He CNC machining It is an automated turning and milling cutting process in which material is removed from a block with a rotating tool.
In it CNC machining By milling, the cutting tool moves in all three dimensions to achieve the desired shape in the final piece. Generally, the cutting tool in milling CNC It rotates around an axis perpendicular to the board containing the material or piece to be cut.
CNC machining process for prototyping
- The first thing is to know the design of the piece in 3D, the information on the material that will be needed and the final treatments for the piece. mechanized by CNC. Afterwards, the program is prepared CNC suitable for the design to be made.
- Next, the material requested by the client is introduced into the machine to begin with the CNC machining and it works according to the entered program. There is always an operator who supervises the work and changes the tools to obtain the final piece.
- Once the CNC machining, you obtain the piece that is cleaned and all the corners and burrs are removed.
- When the part is clean, it is checked that the prototype is correctly machined and if there are any problems.
- The next step is to give it the treatment requested by the client, it may be a surface treatment or the piece simply has to be painted in a specific color requested by the client.
- Once the part is finished, it is sent for control by 3D detection to the Quality Testing Department. When everything is reviewed and approved, the final pieces are sent to the client for final approval.
Advantages of rapid prototyping based on CNC milling
- Quick and effective communication of design ideas.
- Effective validation of design fit, form and function.
- Greater design flexibility with the ability to quickly move through multiples. design interactions.
- Fewer production design errors and better final results.
Rapid prototyping by CNC machining It can be made in rigid materials such as aluminum, copper, steel or brass, as well as in hard plastics and other materials such as nylon, carbon fiber, polycarbonate or PEEK.
The surface treatments of the final piece can be painted, polished, anodized, etc.
