Precision CNC Machining

5 Common Challenges of Using CNC Machining


CNC machining is an efficient and vital means of operating metal fabrications in the modern manufacturing industry. Its technology is a combination of complex computerized programs combined with mechanical engineering to offer computer numerical control (CNC) such as the Precision CNC Machining at Intrex Aerospace.

Despite its efficiency and vital usage in various sectors such as metal fabrication, it has some common challenges. However, while challenges are there during CNC machining, the situations can be controlled through the right approaches. 

Complex Geometry

Generally, there are certain instances where the CNC machining cannot deliver to expectations, yet it is work that can be completed by an experienced artisan. The CNC machines have patterns and logos that they can execute with precision, but it is always limited to specific computerized programs such as circular patterns, straight lines, and circles. This challenge of operations is mostly just a technical hedge that can be solved with advanced CNC machining. Older CNC machines operate with only one, two, or three axes, while new CNCs possess a wide range of movements. 

Data Processing

CNC is limited to operating within the boundaries created by computerized systems. However, its performance is affected by the software running the machine. In some cases, the CNC machining will only function faster or slower based on the instructions sent by the computer under control. However, this is solved by updating the hardware to a much more advanced program. Or the used program or software can be kept pending to give room for more advanced software. With a powerful and versatile piece, it will operate smoothly and much faster based on the levels computerized in its software.

High Cost

CNC machines are very expensive and require a huge financial outlay to have them running in any company. This is even harder for new businesses that are only launching their operations with no advanced equipment. However, the challenges of initial financial pull are offset by the return of having a CNC machine in the company. Despite its heavy financial demands, the return on investment is a sure bet that yields lots of profits with indirect benefits including faster operations, precise results, longer operations, and high productivity.

Expensive Repairs 

The initial cost of CNC machining is very high. Its repairs are no different, which poses a challenge to small businesses who would love to invest The complexity of its hardware and technology can be hard to find or very expensive. The mechanical engineers who can handle such software may also not be available for fast response in the case of technical challenges. However, technical breakdowns can be avoided through preventive approaches and maintenance. Conducting regular inspections of both the hardware and software could be key to avoiding any complex technical problems that can halt an operation. 

Lack of Expertise

In the past, complex machining was operated by artisans or engineers with experience and understanding of the subjects. This had an indirect advantage because the expertise was always available. However, the CNC has simplified the operations since it knows what to do and how to do it with minimal supervision required. Despite the minimal supervision, CNC sometimes experiences some challenges which require attention. The experts, however, must understand intensive learning to meet the knowledge level to manage it. Even so, it is a challenge to pay high fees to meet the CNC machining operation levels.

CNC machining is not perfect, but its benefits supersede the challenges it has. With proper planning, operations, and maintenance, a smooth running of the manufacturing processes is achieved.
