CNC machining has revolutionized part manufacturing, enabling accurate and efficient production. However, when dealing with small batches, costs can skyrocket due to initial machine setup, setup time and tool amortization.
In this article, we will explore strategies to reduce costs in small batch production without compromising quality in industrial machining.
Design for manufacturability optimization (DfM)
Design for Manufacturability (DfM) is a key approach to minimizing costs in CNC machining. Reducing complex geometries reduces machining time and tool wear. Also, standardizing materials can reduce procurement cost and shorten lead times.
On the other hand, avoiding unnecessary tolerances also helps to reduce the need for additional adjustments and quality checks, which improves part manufacturing efficiency.
Use of appropriate tools and processes in the manufacture of machined parts
Selecting the right tools and optimizing machining parameters are key strategies for improving efficiency in small batches. High-speed carbide tools allow faster machining with less wear, reducing cycle times.
In addition, in some cases, CNC milling may be a better alternative to CNC turning for generating complex geometries with fewer setup steps.
Finally, using 4- or 5-axis CNC machines helps to minimize the need for part setups, optimizing the production of machined parts.
Automation and reduction of preparation time
Reducing setup time is essential to improve profitability in small batch manufacturing. The use of advanced CAM software optimizes tool paths and reduces machining times. In addition, designing modular clamping systems allows for quick part changeovers without lengthy setups.
Lights-out production, where CNC machines work unattended, is an efficient strategy to maximize equipment utilization and make online machining more cost-effective.
Purchasing strategies and materials management in industrial machining
Purchasing materials and managing inventory efficiently is crucial to reducing costs. Purchasing in strategic volumes can lower the price per unit.
Another strategy is to optimize material usage through nesting software, which minimizes waste. In addition, using leftover parts to make smaller components or prototypes can make material use more efficient, thus optimizing part manufacturing through CNC machining.
Intelligent outsourcing of CNC machining
For companies that require small batches, outsourcing production to specialized prototyping and small batch shops can be a cost-effective solution. Platforms such as Proto&Go! offer on-demand manufacturing, eliminating the need for investment in in-house machinery.
The bottom line is that CNC machining for small batches does not have to be expensive if smart strategies are applied. From optimized design to automation and outsourcing, there are many ways to reduce costs without compromising the quality of the final product.
