What is CNC Machining?
CNC machining is an extensively utilized manufacturing process that employs automated, high-speed cutting tools to create designs from metal or plastic stock. Conventional CNC machines include 3-axis, 4-axis, and 5-axis milling machines, lathes, and routers, which vary in how CNC parts are cut. Skilled machinists program tool paths based on final part geometry, using CAD models. CNC machines precisely and consistently cut most metal alloys and rigid plastics, making custom machined parts ideal for numerous industries. Mucision provides CNC services and custom CNC quotes for over 40 materials.

Available Finishes
CNC Milling Tolerances & Standards
| Description | General Tolerance or Standard |
|---|---|
| Maximum Part Size | Milled parts up to 80” x 48” x 24” (2,032 x 1,219 x 610 mm). |
| Distance Dimensions | For features of size (Length, width, height, diameter) and location (position, concentricity, symmetry) +/- 0.005”. |
| General Tolerances | We adhere to ISO 2768 standards, maintaining tolerances on metals at +/- 0.005″ (+/- 0.127 mm) and on plastics and composites at +/- 0.010″, unless specified otherwise. |
| Precision Tolerances | We manufacture and inspect to tight tolerances, including sub +/- 0.001″ tolerances, per your drawing specifications and GD&T callouts. |
| Minimum Feature Size | 0.020” (0.50 mm). This may vary depending on part geometry and chosen material. |
| Threads and Tapped Holes | We can accommodate any standard thread size. We can also machine custom threads; these will require a manual quote review. |
| Surface Finish | The standard finish is as-machined: 125 Ra or better. Additional finishing options can be specified when getting a quote. |
| Edge Condition | Sharp edges will be broken and deburred by default. Critical edges that must be left sharp should be noted and specified on a print. |
CNC Machining Design Guidelines
| Features | Descriptions |
|---|---|
| Internal corner fillets | Design internal corner fillets with radii 0.020″ – 0.050″ larger than a standard drill size. For internal corner radii guidelines, follow a drill diameter to depth ratio of 1:6 (1:4 recommended). |
| Floor fillets | To enable the same tool to effectively remove material from the interior, ensure floor fillets (floor radius) are designed smaller than corner fillets (corner radius). |
| Undercuts | For optimal accessibility during the machining process, ensure undercuts are designed to standard sizes and positioned away from corners to accommodate the cutting tool. |
| Tapped/threaded hole depth | To guarantee complete thread formation, provide tool clearance that extends marginally beyond the tapped hole depth. |
| Complexity | Minimize the number of small cuts to help decrease CNC machining expenses; strike a balance between functionality and aesthetics by incorporating only essential design features. |
