Common Challenges in Custom CNC Machined Parts Production

The development of custom CNC (Computer Numerical Control) machining is a milestone in the manufacturing sector since it allows the production of complex parts with both form and functionality. However, just as any advanced process, there are difficulties that even arise when it comes to the production of custom CNC machined parts. In case of companies like RMT, which focus on providing superior CNC machining services, it is important to identify these challenges in advance in order to ensure successful overall results and satisfied clients.

Taming the raw materials

The first issue that emerges with CNC machining is the choice of the material that will be used in producing the custom parts. Different instruments have varying characteristics such as hardness, machinability, and durability potential and these factors will have a direct impact during the machining operation. Here at RMT, we have ways to overcome this challenge through performing material testing and further consulting with the clients for the specific projects.

Deeming Accuracy and Tolerances 

Meeting the demanded accuracy levels and close tolerances is yet another troublesome aspect in the process of custom CNC machining. In any of the above industries, a small error will compromise the form, fit and function of the final part. CNC may achieve a significantly high precision but aspects such as tool wears, machine calibration and part fixturing may still bring about variations.

In the case of RMT, tight tolerances are a more important concern than cost. All the cutting is done on sophisticated CNC machines manned by professional machinists who supervise the entire workflow so that parts are manufactured with close to ideal dimensional parameters.

Sophisticated Designing and Integrating Complex Geometries

With the rise in demand for bespoke components that are high performing in the recent past, there has been clear shift in demand for more complex designs. Complex geometries are frequently encountered in the components, which exceed the limits of standard CNC machining equipment. Such designs may require multi-axis machining or special tooling, which inevitably raises setup time and a possibility for mistakes.

RMT uses advanced multi axis CNC machines to manufacture complex geometries whilst utilizing engineering specialists who write programs for the machines to create the required complex geometry shapes. Due to their qualifications and experience, RMT is able to manufacture components which satisfy the requirements of even the most complex design.

Lead Time and Cost Control

Although there are a lot of benefits offered by CNC machining, the process is also expensive and time consuming, especially for low volume or prototype type of work. It becomes expensive to manufacture products because of the time required to set up, the tooling and the use of specialized equipment. It is equally a nightmare for clients operating on tight deadlines since there are usually long lead times due to complexity in set ups or custom tooling, which is a nightmare to clients operating on tight deadlines.

The challenges mentioned earlier are addressed by thanks to the optimization of the production processes and the use of automation in order to cut down on costs. With good planning and a well-thought-out project, RMT focuses on bringing down lead times and offering affordable solutions to clients while maintaining quality standards.

Control and Proofing of Quality

One of the most important challenges in the production of custom CNC machined components is making certain that referring to particular components and parts is able to meet the relevant quality level. The aerospace, automotive, and medical manufacturing industries are extremely disciplines, in which even the smallest flaw can be critical. Therefore, the quality of parts produced must be thoroughly inspected and verified.

RMT has a well-organized quality control system, employing the use of sophisticated inspection devices like CMM (Coordinate Measuring Machines) and lasering systems in order to check and validate the dimensions and integrities of each part. Quality of the parts manufactured is guaranteed because all the parts that leave the facility have been designed and manufactured in accordance with the requirements.
