Precision CNC Machining

Machining involves processes that remove excess material from a workpiece to make it match a design plan. Precision CNC machining produces results with higher accuracy within tight tolerances based on complex designs. CNC machines can handle machining tasks independently, thereby reducing the risk of human error.

At Metal Works of High Point, we specialize in CNC precision machining for creating custom metal components. Our facility includes CNC machines for milling, lathing, and tooling high volume orders. We also provide valuable in-house services for complete product creation and management.

The Machining Process

The CNC machining process has four basic steps, including:

• Designing the CAD Model. Product engineers or design specialists create a CAD design model or rendering of the desired part. The design software takes into account the limitations of CNC tools and processes to ensure the design is possible to achieve while still fulfilling the project’s primary objectives. Designers can test the product through virtual simulations and assess different thicknesses, materials, and part complexities before finalizing their design.
• Converting the CAD File to a CNC Program. Once the CAD file is complete, it is run through a program, typically CAM software, to generate a digital programming code that the CNC machine follows to produce the part. The most common programming language is G-code, which dictates when, where, and how the CNC equipment moves. M-code designates the CNC machine’s miscellaneous functions, such as the removal of the machine cover.
• Preparing the CNC Machine. Operators position the workpiece into the machine using the appropriate workholding device and attach the required tooling, such as end mills and drill bits, to the correct machine components. Once this is done, the operator can run the CNC program.
• Executing the Machining Operation and Part Production. Once setup is complete, the CNC equipment begins to follow the program’s instructions in a repetitive, step-by-step manner to execute the precise removal of material until the workpiece matches the original design within set tolerances. Once complete, the workpiece moves onto the finishing stage.
