In high-tech sectors like automotive, aviation or aerospace, as well as in more common sectors where the use of standard parts is essential, machining parts is a constant need. Whether to design a mould or a prototype, reproduce original parts or to produce new ones, this manufacturing technique guarantees very precise results, particularly when creating parts with complex geometries using various materials. Thanks to the various technologies associated with it today, this kind of operation is done very quickly. However, regardless of the material and the anticipated outcome, you must follow some key steps for best results.

Approving the Technical Drawings

This is a preliminary step that should be mentioned in the context of an efficient machining process. Before beginning any work, the provider must in fact validate, with the customer, the various data found in the technical drawings provided, be it the sizes, shapes, materials or degree of precision sought for each piece of the part to machine. The slightest misunderstanding or mistake can strongly impact the quality of the final result. Similarly, it is important to know that based on these different parameters, the right machining process will be chosen.


Computers are used in the very early stages of modern machining processes. Once the various technical drawings have been validated, they are then modelled using various software providing a 3D view of the part about to be made, and its different surfaces.

Choosing the Right Tools

The right machining tool will vary depending on the material to be processed and the complexity of the part. Different machines and tools are used to do the milling, boring, mortising, drilling and many other machining processes required to make a customized part and to do different things to the material. The choice depends on what result is desired.

3 or 5 Axis

A few years ago, parts machining was done exclusively using 3-axis. This somewhat limited design possibilities and made the work more labour-intensive and less precise for complex parts. Today, this technique is still used, especially for work on flat surfaces, but is gradually giving way to 5-axis machining. This technique, which works the material in 5 directions at one time, enables more precision-work on all types of materials. It requires more preparation and work, but it is also quicker and more profitable.

Machining, Itself

After choosing the material and following the previous steps, you can begin machining the part itself. This can be done manually by using different machines. However, thanks to improvements in many CNC machining tools, some or all of the process can now be automated until the part is completed.

There! Your part is made and ready for its intended use. Remember, however, that a certain expertise and quality materials are required when machining parts, if you want optimum results. USIMM provides this expertise, as well as a full line of materials. We can help you with any 3 or 5-axis machining projects, from start to finish.
