How to Prepare CAD Drawings For Manufacturing
CAD drawings are very important to design and manufacturing to complete the products, whatever it is metal or plastic parts, which usually means the computer-genterated CAD drawings will help us on these, But most of designers or product developers may not fully understand how the files will be used during processes, so most of time, they will always provide one of them to quote or manufacturing. Today, from our manufacturer’s perspective to explain why we always ask them to provide CAD drawings included 2D and 3D drawings together, so that you can use computers to make both two different formats to us for making finished products much more fastest, accurate and cost-effective.
Below are two formats you need to prepare for manufacturing
What is a 3D CAD Drawing?
3D CAD is short for computer-aided design, It is a technical system mainly used by engineers, architects and artists to design and produce technical documentation drawings 3D software is used to make data model, which contains all of 3D dimensional data, so you can see it like one solid product from computer screen, also you can look at it from different angle.
A three-dimensional model provides the viewer with a perspective of depth. Some of the best 3D software include UG, Solidworks, rhino, Catia etc, 3D CAD drawings are more interactive with the users. It makes a manufacturer produce products in large quantities. The 3D CAD drawing is very effective software for our manufacturer’s production.
Visual reality is an example of three-dimensional illustrations. It creates interactive pictures and images making the designer feel involved. The 3D process has been made very accurate and fast. It helps manufacturers to produce different shapes in a very simple way.
How is the 3D CAD File Used in Manufacturing?
3D files usually can give our manufacuter some of important points, which included whole product’s geometry feature and overall size checking out. Well know that whole product function and assemble. If this is one product assemble, we can see it product function and design purposed. If this is one single part, 3D file can help us to review overall size then order raw material, also, we can use 3D file to transform our CAD programm into CNC machine ( Usually, we call it G-code), then get our CNC machines to milling & turning various of shape to meet your expection.
3D files also can help us to calculate exact part weight to checking out the product volume and packaging. We are very clear know how we will pack your product or parts.
What is a 2D CAD Drawing?
2D CAD Drawings is a technology used by drafters to design, draw and edit technical illustrations. It is like an electric drawing board which replaces the existing paper drawing. 2D enables users to draw elegant technical drawings without the use of technical drawing tools. Usually, 2D drawing is a two dimensional drawings, the designer usually need to make three different views to shown whole part, also some of details points.
How is the 2D CAD File Used in Manufacturing?
2D CAD drawing is very key points to our manufacturer, We can usually 2D file to know more details information on our products or parts, Every mechanical engineer indeicate every important details points or area in order to tell manufacturer how they want to get final products, so 2D CAD drawings our engineers have to include below points,
- Hole sizes, locations and type of threads,
- Material types and Surface requirement
- Physical dimension and tolerances
- Critical dimensions, Radius, Chamfer requested.
- Noted part fitting dimension with another part
2D drawings should contains enough information to make each of parts, Our every machinists, operationer and quality controler also must clear know and understand what the drawings included, how to operate and inspect our parts,
Currently, our deisgner and mechican engineer need to know how will be used for products, or what’s function and purposed for parts, and remark all of these information to 2D drawing, so when our manufacturers will be very clear know what’s the final finishing parts as your expected.
Of course, to be our CNC machined industry, both 2D and 3D will be requested, it will reduce our manufacturers’ time and cost to make quotation and production in shorter time, Also, our QC will be able to inspect the parts what’s your final for parts.
Which is Best for Your CNC Projects, 2D or 3D drawing?
Regarding our CNC projects, we always are looking for to have 2D and 3D drawings together from customers. This will give us more information know what you want, you will request, which is very helpful to make accurate cost calculation and manufacturing processes, so they can provide more valued suggestions for modification before production.
Of course, our services that rapid prototype and low-volume production will be help you to achieve your design. As always, we will be waiting for your inquires to start next new projects, our sales team will give you quotation and feedback on design, manufacturing in shortest time.
