What Is CNC Machining and How Does It Work?
CNC (Computer Numerical Control) machining is a precision manufacturing process that uses computer-controlled equipment to shape solid materials into finished components. Guided by programmed instructions, cutting tools remove material from a metal or plastic workpiece to achieve the required dimensions and geometry based on a 3D CAD model.
The process uses G-code to control tool movements, cutting paths, and machining operations. This automation helps produce accurate, consistent parts while reducing manual intervention and supporting efficient production.
Common CNC machining methods include CNC milling and CNC turning, each suited to different part geometries and manufacturing requirements. CNC machining is widely used for rapid prototyping, one-off components, custom parts, and low- to mid-volume production across various industries.

Custom CNC Machining for Prototype and Production Parts
Every component has unique manufacturing requirements. Our custom CNC machining process begins with an understanding of your engineering drawing or CAD model, material specifications, tolerances, application, and anticipated production volume.
We evaluate these requirements to identify suitable equipment and machining processes. Where appropriate, process selection can help reduce unnecessary setups and secondary operations while supporting consistent production.
Our custom machining capabilities support:
- Prototype components and initial production quantities
- Short-run and repeat production
- High-volume manufacturing programs
- Complex turned and mill-turn components
- Swiss-machined parts
- Multi-axis machined components
- Custom fasteners and specialty hardware
- Engineering and industrial components
From Prototype Development to Production
For manufacturers developing a new component or preparing to scale an existing product, we can review the part requirements and determine an appropriate machining approach.
Our stated production range extends from a single prototype to 500,000+ parts annually. This flexibility supports projects with different production demands, subject to part design, equipment suitability, and project requirements.
Share your drawing, material requirements, target quantity, and application with our team to begin the manufacturing feasibility review.

CNC Machining Capabilities
CNC Turning Services
Our CNC turning capabilities support prototype, production, and complex turned components. Live tooling, Y-axis, dual-spindle, and multi-axis equipment allow us to combine turning with milling, drilling, threading, grooving, and other operations.
Our turning capabilities include:
- 2-axis bar-fed CNC turning
- Y-axis dual-spindle turning
- 9-axis mill/turn machining
- Live tooling
- Swiss CNC machining
- High-volume bar-fed production
- Prototype and production turning
This broad range of CNC machining services allows us to produce shafts, bushings, fittings, fasteners, pins, sleeves, valve components, and other precision CNC machining parts.
Custom CNC Machining
Every component has different manufacturing requirements. Our custom CNC machining approach starts with your drawing, model, material requirements, tolerances, production volume, and application.
We select the appropriate equipment and manufacturing process based on your specific requirements rather than forcing every part through the same machine. This approach supports both simple and highly complex components while helping reduce unnecessary setups and secondary operations.
Our custom CNC service supports:
- Prototype components
- Short production runs
- High-volume production
- Complex turned components
- Swiss-turned components
- Multi-axis machined parts
- Custom fasteners
- Engineering and production components
For manufacturers requiring CNC machining prototyping, we can produce prototype quantities using the same types of equipment and processes used for production. This provides a practical path from prototype development to repeat production.
Direct CNC Machining Services for OEM Manufacturers
Working directly with your machining manufacturer can simplify communication and provide a clearer path for discussing component requirements, production planning, and manufacturing questions.
Resolute Precision’s direct-manufacturer model allows customers to work with the company producing their parts rather than purchasing through a broker or distributor.
This approach supports direct technical discussions about:
- Component design and manufacturing feasibility
- Material and machining process selection
- Production quantities and repeat orders
- Secondary processing requirements
- Pricing and quotation details
For additional processes such as heat treating, EDM, grinding, and coatings, we coordinate with qualified partners where required.
Direct CNC Machining Services for OEM Manufacturers
Resolute Precision Manufacturing holds ISO 9001:2015 certification. Our quality management system supports controlled manufacturing processes, in-process and final inspection, and applicable customer-specific requirements.
We review component drawings and production specifications to understand the quality expectations associated with each project. Inspection requirements, tolerances, documentation, and any additional quality provisions should be discussed during the quotation process.
For projects requiring secondary manufacturing operations, our team can also coordinate applicable services through qualified partners.
Frequently Asked Questions
What is the minimum and maximum part size RPM can machine?
Our bar-fed turning covers parts from 3/8″ to 3.2″ diameter with bar stock up to 12 feet long. Chucked turning handles parts up to 25.5″ diameter. Milling envelopes reach up to 20″×50″ on vertical machining centers and 500mm on horizontal centers.
Does RPM sell direct or through distributors?
We sell exclusively direct to manufacturers. There is no distributor between you and our shop. The price you receive is our price from the machines that make your parts.
