Precision mechanics: why using CAD/CAM software?
Discover how CAD and CAM software can help you
Precision mechanics demands extreme finishing and tolerances. As the first sector to adopt CAD and CAM, the industry uses this software to guarantee precision and optimise its processes. In this article, find out more about their essential role in mechanical innovation.
The challenges of precision mechanics
Precision engineering demands impeccable finishing and smooth surfaces, all on complex parts, in a short time frame and with very little tolerance for errors. Essential in the aeronautics and aerospace industries, but also in the automotive, medical and electronics industries, the welding of each part is carried out on a microscale and requires cutting-edge expertise. Find out more about Siemens solutions for the automotive and transport industries. CAD/CAM tools are essential in these applications, as they enable us to anticipate the slightest irregularities, manage detailed geometries and speed up the transition between design on the shop floor and manufacture on the machines. They enable reliable production with limited loss of materials.
The role of CAD in part design
- Accurate 3D modelling: digital CAD software enables your staff to work together on your products before sending them off to manufacture. 3D modelling tools from data processing define a solid basis of your parts before the machining stage.
- 2D drafting and nesting with NX: by combining the Drafting module for creating detailed drawings and Nesting for optimising cut-outs, Siemens NX offers a complete solution for accurately preparing machining and optimising manufacturing.
- PMI (Product Manufacturing Information): allow your staff to add and access model annotations using PMI (Product Manufacturing Information), including dimensions, tolerances and manufacturing specifications. This information is transmitted directly to CAM, ensuring accurate machining and manufacturing on milling, turning and other mechanical equipment. This approach ensures error-free production in line with technical requirements.
- CAE to simulate precision mechanics: Siemens, with its simulation software Simcenter (3D and Nastran), enables mechanical performance to be checked prior to machining using advanced multiphysics analyses. These tools make it easier to check structures, acoustics and movement, while reducing dependence on physical prototypes.
The role of CAM in precision mechanics
- Generation of toolpaths for CNC machines, with milling as the main process.
- Reduction of material waste and optimisation of production cycles.
- Automation of operations (part positioning, tool selection, optimisation of passes) to reduce human intervention and speed up production.
- Optimum precision thanks to the exact execution of machining trajectories, guaranteeing micrometric precision and limiting variations between the parts produced.
An asset for your company's competitiveness
In precision mechanics, the use of Siemens CAD and CAM software makes it possible to improve product quality and precision. These systems guarantee the micrometric precision of products, while analysis and simulation tools facilitate rigorous quality control. In addition, the automation of repetitive tasks and the standardisation of processes, together with clear and comprehensive documentation, optimise manufacturing and ensure consistent production, thereby boosting the company's competitiveness.
