Locating faces
The drawing specifies each reference face and its relationship to the other features. Include any required flatness, parallelism or surface finish.
CNC plastic milling · Aurora, Illinois
CNC milling for custom plastic parts.
CDS mills engineered plastics, aluminum, brass and bronze for new components, replacements, prototypes and production work.
Bring the drawing or available part information. Your specified material, dimensions and tolerances establish the machining requirements.
Faces, pockets, slots and contours
Faces, pockets and hole patterns to your drawing.
In CNC milling, a rotating cutter removes material from a held workpiece. Faces, pockets, slots, hole patterns and contours can form mounting surfaces, recesses and other interfaces.
Feature size, depth and arrangement affect cutter access and workholding. The complete customer drawing lets CDS confirm whether the specified part fits the machining equipment and setup.

Pockets and thin sections
A deep pocket or thin wall can change how the workpiece is supported and how a cutter reaches the material. Neighboring features belong in the same drawing.
Hole patterns and alignment
Hole sizes and locations need drawing references. Customer-specified datums and positional tolerances establish the machining requirement.

Particle evacuation and air filtration
The department has an in-house-designed particle-evacuation and air-filtration system, designed to eliminate dust and potentially hazardous out-gassing.
Material, support and dimensional control
Plastic changes the machining requirements.
Engineering plastics can respond differently from metals to heat, restraint and cutting forces. The exact grade and stock condition belong alongside the part's geometry.
Heat and material movement
Thermal expansion, elasticity and stock stress can affect dimensions during and after machining. Different grades and stock forms can behave differently under the same conditions.
Support and feature access
Clamping, unsupported sections and cutter access influence how the part can be held. Thin walls, uneven sections and closely spaced features need consideration together.
Specified material
Supply the full grade and any required brand, filler or permitted substitute. The engineered-plastic material pages explain general material behavior; the customer specification controls the grade for machining.

Your drawing tolerances and inspection requirements
The customer drawing identifies critical dimensions and permitted variation. Tolerance feasibility depends on material, geometry, datum relationships, inspection condition and the particular setup.
CDS confirms machining feasibility for the specified part, including overall dimensions, surface finish and requested inspection records. Required tolerances are reviewed with the quotation.

Share the drawing and the features that matter.
A current drawing and revision provide the clearest starting point. A specification, sketch, model or sample information can also begin a discussion.
- Part and material
- Overall size; faces, pockets, slots, hole patterns and contours; resin or metal, exact grade, stock form and known stock condition.
- Fit and acceptance
- Critical dimensions, datums, positional relationships, mating parts, buyer-specified tolerances and functional finish. Identify the required inspection condition and any unresolved drawing details.
- Quantity and records
- Prototype or production quantity, quantity tiers where useful, current revision and requested date. Identify required inspection, documentation, marking and packaging.
