CNC — or computer numerical control — machining is among the most effective ways of producing on-demand products in the current marketplace. Despite the availability of new production methods, such as 3D printing, CNC machining is still in high demand for its several benefits, including:
But how much does CNC machining cost when you’re planning for your next project? This guide explores the principles influencing CNC machining prices and how to cut costs without compromising quality.

CNC machining is an automated subtractive process that uses high-speed cutting tools to shape a plastic or metal workpiece into the final product. The most common CNC machines used to achieve accurate outcomes include:
You can operate these machines using a computer-aided design (CAD) model. A machinist programs the CAD model to provide precise geometric info for the machining process. This accurate and automated process is essential to the manufacture of custom products like:
CNC machining costs can be calculated per hour or per part, depending on the project’s complexity and volume.
Hourly Costs:
The hourly rate for CNC machining depends on the type of equipment used. For example:
Per-Part Costs:
When pricing is based on individual parts, costs vary depending on complexity, materials, and production volume.
While these price ranges provide a starting point, other factors like material selection, machining time, and batch size can influence final costs. To get the most accurate quote, it’s best to work with a CNC machining provider who understands your project’s specific requirements.
As seen above, part complexity is a central factor for determining cost. An increase in the part complexity leads to higher programming and machining time. Another factor that defines the price is the material used in the production process. For instance, aluminum is easier to machine than stainless steel or titanium. Order size also plays a key role, as larger production runs benefit from economies of scale, reducing the cost per part.
Costs may also differ depending on the type of machine that is used. The standard three-axis machines are relatively inexpensive compared to the five-axis machines, which are used for complex shapes and designs. Strict industry standards, particularly in sectors like medical manufacturing, can drive up costs due to rigorous quality control and compliance requirements.
Understanding the factors that influence CNC machining costs—such as part complexity, material selection, and production volume—helps in setting reasonable expectations for pricing. To get an accurate quote, it is always advisable to work with a CNC machining provider who understands the specific needs of your project.
Several elements contribute to the overall price of CNC machining. Understanding these factors can help you plan your budget and identify opportunities for cost savings. Below is an overview of the main cost drivers:
The following sections provide a more detailed look at each factor, helping you make informed decisions for your project.
Your material selection plays a significant role in determining the cost per part of a CNC machining project. Materials like stainless steel or titanium are valued for their strength, durability, and resistance to wear. These raw materials generally cost more than softer metals and plastics.
Machinability is another key determinant, as the tooling is more prone to wear when machining harder materials. This reduces the machine’s life span while increasing servicing needs, which can escalate the cost of CNC operations. In addition, soft, raw material can be very difficult to machine due to high elasticity, increasing the overall cost of CNC machining.
Fluctuations in the raw material market also influence pricing. The demand and availability of your choice of material can directly increase or decrease your CNC machining costs. The level of post-processing required to achieve the desired final surface finish can also add to the expense. Common processes include polishing, anodizing, powder coating, and heat treatments, each contributing to additional costs based on complexity and material type.
Finding the perfect balance between different material attributes and cost efficiency is essential for an optimal and budget-friendly CNC machining project.
CNC machines come in different sizes and have varying functionalities to manufacture large, small, complex, and simple parts. Their pricing depends on their:
Apart from these factors, other accessories, tools, and software licenses add to the total cost of machine setup. Depending on the CNC machine, these additional features may include
You also have to factor in the price of programming the machine. A CNC programmer costs roughly $30 per hour. This cost may be higher depending on the job complexity and whether the programmer is on a full-time contract or project basis. A certified CNC programmer understands how the machine works, the tools needed, and the type of materials to process.
The programmer is often tasked with first analyzing all the project specs, including:
Afterward, the programmer can create a series of codes for the CNC machine to understand and follow. Later, the CNC operator uploads the instructions onto the machine, runs tests, enhances the codes, and ensures the CNC machine executes the command.
How much does CNC machining cost per hour? The CNC machine’s upfront costs and expected yearly usage of around 5,000 hours influence machining costs. Machinists often calculate shop rates by dividing the machine’s price by the total annual usage. The final CNC machining cost calculation varies depending on the machine type and capability.
For instance:
Labor and overhead significantly impact CNC machining costs. Skilled machinists — responsible for programming, operating, and quality-checking machines — typically earn $20 to $50 per hour, depending on experience and region. Facility overhead, including utilities, rent, and operational expenses, adds to the total, particularly for large workshops with advanced equipment. Machine maintenance is another expense.
Regular servicing, tool replacements, and machine downtime enable precision manufacturing but contribute to overhead. These costs are distributed across projects, meaning more complex jobs or low production runs may bear a higher share. Understanding these elements helps explain pricing so you can account for true production costs.
You can take several steps to lower the total cost of your CNC machining project.
Simplifying your part design is one of the most effective ways to reduce CNC machining costs. Avoid intricate geometries that require advanced five-axis machines or extended machining times. You can focus on lowering design complexity to minimize the number of tool changes, as each change adds time and tooling costs.
Additionally, consider optimizing features to streamline production, such as maintaining uniform wall thickness or reducing unnecessary cavities. Collaborating with an experienced CNC provider like The Federal Group USA during the design and engineering phase can uncover practical ways to achieve cost efficiency.
You can lower the cost of your CNC project by selecting materials that balance affordability with your functional needs. For instance:
Standardizing your choice of material across the production line further reduces waste, simplifies procurement, and optimizes machining efficiency.
Ordering larger quantities of parts is a straightforward way to reduce per-unit costs. CNC machining involves fixed setup and programming costs that remain constant regardless of batch size. Spreading these expenses across a higher volume of parts can significantly lower the cost per piece. Batch production also reduces material waste and optimizes machine usage, leading to further savings.
