CNC Machining Design Support — DFM, Drawings and GD&T
Guenzo prepares CAD models and drawings for parts produced on 3-axis, 4-axis and 5-axis CNC mills and lathes. We design for the actual capabilities of your supplier — tool access, fixturing, finish, tolerance — to keep parts manufacturable and cost-effective.
Who this service is for
- Companies producing machined parts for assemblies
- Engineering teams that need DFM review before quoting
- Startups moving from 3D-printed prototypes to machined parts
Problems we solve
- Parts designed without tool access in mind — expensive or unmachinable
- Over-tight tolerances driving cost with no functional benefit
- Missing or ambiguous GD&T preventing inspection
- Material and finish choices that do not match the application
Deliverables
- Parametric 3D CAD optimized for CNC
- PDF drawings with GD&T and surface finish callouts
- STEP/Parasolid for CAM
- BOM and material specifications
- DFM report with cost-saving recommendations
Software we use
- SolidWorks (parts, assemblies, drawings)
- SolidWorks Simulation (FEA)
- STEP / Parasolid for CAM handover
- DraftSight / AutoCAD for legacy 2D
Supported manufacturing methods
- 3-axis CNC milling
- 4-axis and 5-axis CNC milling
- CNC turning (with live tooling)
- Wire and sinker EDM where required
- Surface finishes: anodising, plating, passivation, bead blast
Example projects
- Machined aluminum housing for an electronics product
- Stainless brackets and shafts for production machinery
- Conversion of welded fabrications into CNC-machined parts
Process
- Inputs: Requirements, mating parts, tolerance budget, material.
- Design: Model with milling-friendly features and accessible geometry.
- Drawing: GD&T, datums, critical dimensions, surface finish.
- Supplier handover: STEP, PDF drawing, material spec, finish spec.
Frequently Asked Questions
Can you help with CNC machined parts?
Yes. We design parts that are practical for CNC machining and prepare GD&T drawings that your suppliers can quote and inspect against.
Do you work with companies outside Latvia?
Yes. We work remotely with companies across Europe and internationally. Most projects are run by email, video calls, and shared cloud folders.
What CAD file formats can you deliver?
Native SolidWorks (SLDPRT, SLDASM, SLDDRW), STEP, IGES, Parasolid, STL for 3D printing, DXF for laser/waterjet/sheet metal, and PDF manufacturing drawings.
Can you sign an NDA before we share project details?
Yes. We routinely sign NDAs before reviewing concepts, sketches, or existing CAD data.
