Our CAD Drafting Service includes compliant Manufacturing Drawings
What are Manufacturing Drawings
Manufacturing Drawings are also known as Production Drawings or Working Drawings. A full set of Manufacturing Drawings include all the information required for production. No questions should be left unanswered. These drawings are split into to main categories.
1. Part/Component Drawings
These drawings detail the part itself that require manufacturing and are intended for the machinist. They also show the information required for the finishing processes.
The drawings should include the following information. (They should however not show more information that is required.) :
- Material Specification
- Linear Dimensions including Tolerances
- Angular Dimensions including Tolerances
- Geometric Tolerances
- Surface Finish Type and Tolerances
2. Assembly Drawings.
Depending on the complexity, Assembly drawing are often structured into a Top Level Assembly and Sub-Assemblies. This is to give more clarity on the full product. Assembly drawings should include:
- All Sub-Assemblies used within the assembly
- All parts to be manufactured
- All bought in parts including their specific part numbers, manufacturer or supplier
- Fixings such as Bolts, Nuts, Washers etc.
- Bill of materials (BOM) showing a full list of all parts
- The drawings should be illustrated in a way to clearly show how the Product fits together. This should/could include several views (Plan, Top, Side, Isometric etc.) and Exploded Views
- Additional information that might be required such as Weight, assembly instructions should also be included if required.
It is important that good quality drawings show all the information that is required, but no more than needed. An example is to many dimensions or to many views.
