As milling, the finish option with the quickest turnaround. Machined parts are left with visible tool marks and potentially sharp
edges and burrs, which can be removed upon request. CNC machining surface finish is comparable to 125 uin Ra finish.

Milling
|
Turning
|
|
|
Milling is a commonly used processe for machining custom parts. Using rotary cutter to remove material from workpiece. Control the directions of axes, cutter heads' speed, and the pressure to make different shapes. Milling covers a wide variety of different operations and machines, from small individual parts to large.

Turning
|
Turning
|
|
|
Turning is a machining process in which a cutting tool, typically a non-rotary tool bit, describes a helix toolpath by moving more or less linearly while the workpiece rotates.

Lathe CNC
|
Lathe CNC
|
|
|
CNC lathe is a subtractive method to prototype shapes. With the G-Code created, a blank bar of stock material is loaded into the chuck of the lathe's spindle. The chuck holds the workpiece in place while the spindle spins. When the spindle is up to speed, a stationary cutting tool is brought into contact with the workpiece to remove material until the desired geometry is achieved.

CNC Machining and Engineering Design Guide
|
CNC Machining Tolerances
|
General Tolerances
|
Tolerances on metals will be held to +/- 0.005" (+/- 0.127 mm) in accordance with ISO 2768 unless otherwise specified. Plastics
and composites will be +/- 0.010”. |
|
|
||
|
|
Precision Tolerances
|
can manufacture and inspect to tight tolerances per your drawing specifications including GD&T callouts.
|
|
|

|
Size
|
Maximum Part Size
|
Lathe can make size to: 1,575 mm x 813 mm x 813 mm;
Turnning and Milling can make size to: 2,032 x 1,219 x 610 mm |
|
|
||
|
Feature
|
Minimum Feature Size
|
0.020” (0.50 mm). This may vary depending on part geometry and chosen material.
|
|
|
||
|
|
Internal corner fillets
|
Design internal corner fillets to be 0.020” - 0.050” greater than a standard drill size for the radii. Follow a drill diameter to
depth ratio of 1:6 (1:4 recommended) as a guideline for internal corner radii. |
|
|
||
|
|
Floor fillets
|
Design floor fillets smaller than corner fillets to allow the same tool to clear material from the interior.
|
|
|
||
|
|
Undercuts
|
Always design undercuts to standard sizes and away from corners so they are accessible by the cutting tool.
|
|
|
||
|
|
Tapped/threaded hole depth
|
Provide tool clearance slightly beyond the tapped hole depth to ensure complete threads.
|
|
|
||
|
|
Complexity
|
Keep the number of small cuts to a minimum to reduce CNC machining costs; only design in the necessary features to balance
function with aesthetic. |

CNC Machining Surface Finishes
Standard
Bead Blast
Surface will be left with a smooth, matte appearance.
Tumbles
Tumbles vibrating media to remove sharp edges and burrs on CNC parts. Tumbling can remove machine marks on exterior surfaces.
Parts over 8” may require a manual review.
Parts over 8” may require a manual review.
Anodized
Parts can be anodized in different colors—clear, black, red, and gold are most common—and is usually associated with aluminum.
Passivation
Improves corrosion resistance for 200 and 300 series and precipitation hardened corrosion-resistant steels. Thickness is
negligible, about 0.0000001”. Conforms to ASTM A967, AMS-QQ-P-35, MIL-STD-171, ASTM A380, or AMS 2700.
