Avoid Onion Skins – instead use tabs / bridges and screw fix / pin parts to the CNC bed.
Avoid adding tabs/bridges in the recesses of edges of parts tolerance critical areas.
Minimise the use of tabs to reduce part-clean up time.
Check critical tolerances on the inside and outside of curves. Maintain a part tolerance of <0.1mm from drawings where possible for best fitment.
Use chip-breaker cutting tools for optimal machined edge finish and speed. Cut in a single pass where possible.
Ensure structural plywood is used for all wall framing members. Avoid plywood with thin faces being used for framing parts.
Check for internal plywood delamination (part separation). Defect parts with any sign of internal delamination.
Check all sheets are within +/- 0.3mm (nominal) thickness for optimal fitment results.
Use flush-trim router milling tools to clean tabs/bridges off parts. No sanding is required to the edges of structural components.
Ensure part orientation for structural components are parallel to the longitudinal orientation of external plywood faces.
Observe minimum drill hole size requirements.
Internal voids less than 20mm long, and veneer surface openings less than 15mm wide and 70mm long are tolerable on parts.
