3D modeling for CNC

3D modeling for CNC is the process from which the prototype production begins. Today it is quite simple to create a prototype of a product, as well as to make a mold; for this, rapid prototyping technologies are used, in particular such technology as 3D milling.

Creation of 3d models ( 3d models for CNC ) and prototyping is a necessary step before starting production processes. If the design of a new product is already ready, but you still have doubts about its aesthetics and ergonomics, because the sketch sketches do not always look like they were intended, then you need to create product prototype (single copy of the product).

3D modeling for CNC – the process from which the prototype production begins. Today it is quite simple to create a prototype of a product, as well as to make a mold; for this, rapid prototyping technologies are used, in particular such technology as 3D milling. 3D milling is a method of material processing, with the help of which the 3D model required by the manufacturer is created. To create 3D models by 3D milling, a numerical control milling machine (CNC) is used.

At the same time, the manufacturer receives 3d models for CNC quickly and of high quality, and the production process takes place continuously and in multi-stage mode.

KLONA company has in its arsenal CNC milling machines to perform work of any complexity. Before you start making a model, our engineers will help you create 3d models for CNC machines in professional graphics programs.

3D milling Is a method of creating preset volumetric shapes using a CNC milling machine from a material selected by the customer. A modern CNC machine is highly accurate and makes it possible to give the finished product any configuration and shape, regardless of its complexity and materials of manufacture.

Application of 3d milling:

  • manufacturing of technological equipment: molds, master models, stamps, matrices, etc.;
  • creation of presentation layouts (prototyping);
  • production of advertising objects (flat and volumetric);
  • curly cutting;
  • manufacturing of furniture fittings, etc.

3D milling can be done from the following materials:

  • plastic – ABS, polystyrene, polyethylene, polycarbonate;
  • metal (black and non-ferrous) – copper, aluminum, steel, etc.;
  • composite polymers (with the addition of ester resins and fiberglass);
  • stone;
  • wood, composite materials from wood (chipboard, DPV, plywood, MDF).

Stages of 3D milling on a CNC machine

Stage 1 – development of an engineering 3d model products (3d models for CNC) – the creation of the model takes place in professional computer programs for working with 3D graphics.
Stage 2 – preparation of a 3d model for CNC machines – selection of tools and writing a program (algorithm of sequential steps) for the operation of a CNC milling machine.
Stage 3 – milling a trial, check blank , plastic is used as the material for the product. A trial blank will allow you to correct the shortcomings of the product with minimal costs, plastic is chosen as the material, due to its low cost relative to other materials, for example, metal.
Stage 4 – making pure 3d models , taking into account the adjustments made at the previous stage.

The success of the end result of a complex milling process, first of all, depends on the development of a 3D model for a CNC machine – 3D modeling for CNC.

Creation of 3d models for CNC machines is carried out using professional software for working with three-dimensional graphics. Typically, this uses the principles of such a type of three-dimensional modeling as solid modeling.

Solid modeling – the process of designing an object that has all the properties of a physical body. 3D models of objects obtained in this way are more detailed, they reflect even the most insignificant components of the object.

Key benefits of solid modeling:

  • the most realistic three-dimensional model;
  • automatic formatting of drawings;
  • ease of making adjustments to the created 3D model;
  • significant time savings due to the ability to use templates and integration applications, etc.


3D modeling for CNC is a rather complicated process, in order to simplify and automate it, CAD is used – a computer-aided design system – a set of tools and automation tools used in the design of objects.

Among the numerous systems of solid modeling, several main ones can be distinguished: CADDS5, PowerShape, SolidEdge and T-Flex CAD … Each of the systems has its own advantages and disadvantages, and the choice of the system is based, as a rule, on the complexity of the task being performed and the timing.

The world’s largest CAD software provider is Autodesk Corporation supplying the product AutoCAD … It is one of the most advanced 3D modeling software for CNC. Multifunctional and easy to use. Convenient software product, with the help of which the creation of 3d models and 2d models is realized.

Solid modeling programs are based on the principle of “structural block geometry (CSG)”, thanks to which they can be used to easily create complex shapes of 3D objects. In addition to Autodesk software products, SketchUp and Tinkercad can also be distinguished. Solid modeling uses simpler shapes to create complex shapes – cylinder, cube, pyramid, etc.

Benefits of solid modeling programs:

  • simplicity and intuitiveness of the modeling process;
  • the ability to make accurate measurements;
  • ensuring the tightness and integrity of objects of complex shapes.

At the end of the solid modeling process, the customer receives ready-made 3d models for CNC machines, which can be easily translated into machine code.
