At Razrez d.o.o. we use the complete integrated CAD/CAM design programming system Cadman L-3D, simplifying modelling.

Electronic technical documentation is accepted in DXF, DWG, SAT, IGES, STEP, XT, etc.

We work with you to develop and produce the first pieces to your satisfaction before moving on to batch production.

CAD/CAM technology is fast becoming the gold standard for high-speed, accurate production of the desired end product. CAD/CAM is an abbreviation of Computer Aided Design/Computer Aided Manufacturing. This technology has been in use for 40 years in the aerospace, aviation, automotive, and healthcare industries where high flexibility and precision is paramount.

CNC machine programming is the process of writing a programme according to a predefined product development technology.

In computer-aided programming, the NC code is generated using a CAD/CAM system based on the 3D geometry of the product, the available tools and the machining regimes. Computer-aided programming has taken over from manual programming to provide:

  • faster programme creation
  • less chance of errors
  • better use of resources

CAD/CAM is a technology that enables the automated flow from the design of a product to its production, integrating design (CAD) and manufacturing activities (CAM) with the help of computers.

CAD (computer-aided design) is the use of computer programmes to assist in the design, construction, analysis and evaluation, modification and optimisation of a product; in short, it is the path from conception to documentation.

CAM (computer-aided manufacturing) is the effective use of computer technology to plan, manage and control production processes. Based on a CAD model, G code is generated for machining on a machine controlled by a computer. Nowadays, almost all types of machining are based on CAM technology. Unlike CAD, which is used as an aid to the modelling and design of products, processes and production plants, CAM is used as a software support for manufacturing activities, i.e. the control of CNC machines used in the machining and production of products.
