The main distinction between a good part and a great one lies in the craftsman’s mastery and expertise in executing it. The specifications make the product available to consumers, while the manufacturing knowledge and expertise guarantee reliability over time and under various operating conditions.
In the same way, it is important to work with qualified CNC machining companies, as they are experienced in many aspects of machining, as well as in manufacturing, process knowledge, and understanding potential issues that should be addressed well in advance.
Engineering Input Before Production Begins
An experienced CNC machining manufacturer will demonstrate their value-added even before any cutting takes place. While some companies just look at the drawing and start programming, the best ones will review the drawing before programming it.
In this respect, they conduct what is known as the design for manufacturability process, which indicates how the part has to be produced, taking into account features, tolerances, and material. Among others, an experienced manufacturing team will pay attention to problems such as:
- Tolerances that are tighter than needed
- Features difficult to achieve with a standard manufacturing process
- Surface finish that does not match the properties of a certain material
- Threads that may lead to assembly problems.
Identifying problems during this stage is free of charge, whereas identifying them after the design stage is already very expensive, as it means that the tooling has already been made and the production process started.
Material Selection That Matches Real-World Conditions
Indicating the right material on a drawing is difficult. A part that performs well in the controlled environment of a lab might behave differently when exposed to temperature changes and mechanical stress in the real world, for example.
With their expertise, CNC machining professionals can help clients analyze these specific conditions before choosing a specific material to use. The distinctions between such materials as 6061 and 7075 aluminum or 303 and 316 stainless steel can be crucial for the duration of performance and characteristics of the part.
CNC machining providers with great professional experience possess relevant information about the use of various materials in aerospace, oil and gas, robotics, and semiconductor applications, which allows them to apply insights to a new project.
Process Planning That Reduces Variability
Every CNC machining project consists of evaluation of fixturing, tooling, cut sequence, and inspection method choices, which impact the uniformity of parts produced over the entire process.
Less experienced CNC machining manufacturers may get the initial ten parts right, but as the process progresses, the quality of parts goes down due to either tool wear or changes in temperature and pressure.
An experienced company has by now implemented the necessary process controls in its operations to avoid this.
This involves:
- Fixturing design to allow for a stress-free part that will not distort dimensions upon release.
- Tool selection so that efficiency is achieved and the number of tool changes is as low as possible, thus minimizing variations.
- In-process inspection checkpoints are required at regular intervals during machining to correct any eventualities before they affect the entire production.
- Recording of the parameters used in machining of a job before it is re-run ensures the same effect in the subsequent processes.
After-Sales Support That Extends Product Performance
There is more to the relationship between the customer and CNC machining companies than just shipping. A CNC Machining shop that has experience in the industry knows how critical post-delivery support is to the business model of the shop.
When a precision part is shipped, it should arrive complete with its documentation, including dimensional inspection records, material certifications, and other relevant paperwork. The presence of this documentation helps the customer ascertain compliance, affirm their own quality assurance processes, and trace problems in the field back to actual production data.
In case there is any quality-related issue that arises after the delivery of precision parts, then reputable CNC machining manufacturers would offer the necessary documentation as proof to validate their claims instead of making excuses. They will be able to obtain original inspection records, evaluate the process parameters applied, and collaborate with the customer in order to come up with appropriate solutions for the issue at hand.
Industry Experience across Demanding Sectors
Industries that make the highest use of precision CNC machining are also the same industries where the effect of failure of their components would be vastly detrimental. Aerospace industries, oil and gas extraction, semiconductor manufacturing, robotic engineering, and measurement and control also work tirelessly within the limits of what precision machining can deliver.
In fact, experience from such fields equips CNC machinery companies with more understanding of the CNC industry. For instance, if a CNC shop specializes in high-pressure underground tools production, then such machinery would know well what it entails to make a part with a bore tolerance of 0.0003 inches made of hard steel. This will help them understand what to expect in subsequent projects irrespective of the industry in question.
