Additionally, it will outline the information you should have before outsourcing your product development. Continue reading!
Why Opt for CNC Production Machining?
While we have extensively covered CNC machining in a previous article, delving into the realm of CNC production machining requires a distinct understanding. Mastery of CNC production machining entails familiarity with the various steps involved in operating a CNC machine, and this holds true whether you own the machine or outsource the process. In either scenario, staying pertinent in the industry necessitates a comprehension of these operational steps.
CNC production machining manifests in two primary forms: Low-Volume CNC Machining and High-Volume CNC Production Machining. Despite the apparent distinction conveyed by their names, there is more depth to each category than meets the eye. In this section, we will explore both types of CNC production machining along with their respective advantages.
Low-Volume CNC Machining
Low-volume CNC machining is a specialized service focused on crafting small, fully-produced parts within a limited quantity, typically ranging from 50 to 1000 pieces. Also known as small-batch CNC machining, its popularity has surged due to several key factors:
- It effectively bridges the production scale gap between prototypes and original production runs.
- Cost reduction is a notable advantage.
- It provides increased access to emerging markets.
- Ideal for products with short life cycles.
- Offers flexibility in design modifications.
High-volume CNC machining is tailored for the mass production of substantial quantities of materials, exceeding 1000 parts, while maintaining stringent quality standards. Referred to as large-scale CNC machining, this process is highly favored in various industries for its efficiency in producing numerous parts at a reduced cost.
Key advantages of high-volume CNC machining include: Cost-effectiveness stemming from reduced labor and lower overall prices; Capability to produce large quantities of parts efficiently.
Advantages of CNC Production Machining
- Enhanced Production Efficiency and Minimal Wastage:
CNC production machining relies more on machines than human intervention, leading to improved production efficiency. Automated operations and comprehensive work coverage contribute to increased efficiency. Additionally, advancements in software contribute to minimizing material wastage.
- Reduced Dependence on Labor:
Both high and low-volume CNC machining entail minimal labor requirements, resulting in cost savings. While complete elimination of labor is not the case, skilled employees oversee each operation in the production process.
- Heightened Profitability:
CNC machining, characterized by minimal monitoring needs, is a shared attribute in both high and low-volume processes. Leveraging the advantages of CNC machining enhances profitability through reduced manual labor costs and competitive pricing of parts. However, high-volume CNC machining experiences a more substantial increase in profitability due to its larger production scale.
Considerations for Outsourcing CNC Production Machining
Before entrusting your project to a company like ours, there are crucial aspects you should be aware of. Here are three key elements that will equip you with the necessary insights for CNC manufacturing operations.
Understanding the Standard Production Process
Familiarizing yourself with the standard production processes employed in CNC machining is fundamental. To facilitate comprehension, we have outlined the CNC production machining process into four key steps:
- Design a CAD Model:
Initiate the process by creating a CAD file, either in 2D or 3D format, using CAD software. This file meticulously renders each part of the intended product with precise technical specifications. Consideration of your workpiece’s role in achieving the design is crucial, as further elucidated in the materials section for CNC production machining.
- Convert the CAD File to a CNC Program:
Following the CAD file design, input it into CNC software, which analyzes the file for the required programming codes essential for the operation. There are two types of codes in CNC machining: G-code (Geometric code), governing the machine’s movements, and M-code, managing factors controlling the CNC machine.
- Setting Up the CNC Machine:
The setup process involves preparing the CNC machine for the operation, contingent on whether a high or low-volume process is employed. This encompasses various machines such as turning, milling, and grinding machines. A competent and skilled engineer is integral to overseeing the process, a prerequisite for any reputable company engaged in CNC production machining.
- Execute the Operation:
Once all preparations are in order and aligned with the plan, commence the operation. The program guides the CNC machine through its actions, ensuring precision and accuracy in achieving the desired outcome.
Design and Material Optimization
Achieving the optimal design often hinges on a thorough understanding of how to best align the design with available materials. The following tips offer guidance on optimizing your parts’ design while considering material properties.
- Simplify the Design:
Streamlining the CAD file during the design phase helps eliminate unnecessary machining processes, reducing operation time and mitigating potential drawbacks. Removal of superfluous parts prevents additional machining, enhancing overall efficiency.
- Choose the Right Wall Thickness:
Given that CNC machining tools exert pressure on the parts, selecting the appropriate wall thickness is crucial. It should neither be too thin, risking breakage, nor excessively thick, leading to tool hanging, deflection, and fracture.
- Avoid Small and Complex Text and Features:
For projects requiring markings and text, steering clear of small, intricate details is advisable. This approach minimizes costs and simplifies machine operations, promoting efficiency. Opt for larger text or markings instead.
- Use Standard Hole Sizes:
When drilling is necessary, opting for standard hole sizes facilitates smoother operations, saving time and ensuring high precision and accuracy.
Quantity and Lead Time
In CNC manufacturing, the quantity and lead time are paramount considerations. Most modern CNC machining companies accommodate both low and high-volume CNC machining. However, lead time is contingent on factors such as the sophistication of the software, machine up-to-dateness, and operational capabilities.
Attaining optimal quantity and quality within a reasonable lead time involves a comprehensive understanding of the manufacturing process and identifying a company equipped to meet these requirements.
