01
The space inside
Show pocket depth, internal corner radii and access to recessed features. Include the component that must fit inside when useful.
POCKETS & INTERNAL FEATURES
CNC MILLING / CUSTOM COMPONENTS
Housings, precision plates and mounting components. Pockets, faces and hole patterns machined around the interfaces in your assembly.
POCKETS. WALLS. LOCATING FEATURES.
A pocket holds the assembly. A shoulder locates it. A hole pattern connects it. The relationships between these features define the part.
THE GEOMETRY BEHIND THE PART
Pocket / locating face / mounting pattern
01
Show pocket depth, internal corner radii and access to recessed features. Include the component that must fit inside when useful.
POCKETS & INTERNAL FEATURES
02
Identify the datum faces and the dimensions between mounting, sealing and locating surfaces.
DATUMS & MATING FACES
03
Define hole positions, counterbores and threads relative to the functional references on the drawing.
HOLES & THREADS
ENCLOSE
Internal space, wall sections, cover interfaces and mounting positions.
LOCATE
Locating datums, pocket geometry and repeatable assembly references.
CONNECT
Mounting faces, clearance features and the relationship between interfaces.
BEFORE THE TOOLPATH
Send the functional requirements with the complete model. These features deserve a closer look before the machining scope is agreed.
01 / TOOL ACCESS
Identify depth, radii and any areas with restricted access. Mark where the geometry is fixed by the mating component.
Include: depth, corner radii and mating geometry.
02 / PART SUPPORT
Show the wall sections that control function and the faces where appearance matters. Distinguish essential dimensions from general geometry.
Include: wall thickness and critical surfaces.
03 / FEATURE RELATIONSHIPS
Use common drawing references to describe how side holes, pockets and mounting faces relate to one another.
Include: datums and positional requirements.
04 / FINAL CONDITION
State which requirements apply to the completed part. Identify cosmetic faces, masked areas and any added hardware.
Include: finish and final dimensional requirements.
Feasibility and accepted requirements are confirmed for the specific geometry, material and quantity.
MATERIAL TO FINISHED SURFACE
Include the material grade and final surface condition in the same enquiry. Finishing requirements can affect functional and cosmetic surfaces.

SURFACE & SECONDARY WORK
Mark cosmetic faces, masked areas and any inserts or hardware. Confirm the finish and additional operations in the quotation.
MILLING QUESTIONS
Files, feature limits and finishing requirements for a custom milled part.
Send a STEP or STP model and a dimensioned PDF where available. Include the part revision, material, order quantity, surface requirements and any dimensions that control assembly or function. If only one file format is available, send it with a short description of the part.
Include these features in the complete model and identify any dimensions that cannot change. Tool access, wall support, material and workholding need to be assessed together. Feasibility and any suggested changes are confirmed after drawing review.
Tolerance and size suitability depend on the part geometry, material and machining setup. Provide overall dimensions and mark the critical fits and datums. The quotation confirms the requirements that can be accepted for your specific component.
List the required finish, cosmetic faces, masking, inspection points and documents in the enquiry. These are reviewed as part of the finished-part scope, with availability and delivery requirements confirmed in the quotation.
