We prioritize producing parts based on your 3D models

Here is a step-by-step process of manufacturing a camera chamber at Overland, starting from the initial 3D design to the final part using CAM software, CNC turning, and milling machines.

1,Verifying and validating drawings

     Upon order confirmation, we have received and reviewed over ten thousand 2D and 3D CAD drawings from clients. Our thorough checking process ensures that any issues with opening the drawing files or other obvious problems are promptly addressed before production begins:

  • If a part falls outside the capabilities of Overland, we will provide a “no quote” response.
  • We offer suggestions for design improvements to optimize production and reduce costs without compromising functionality.
  • We strive to provide you with the quickest possible lead time for delivery when issuing a quote.

2,Creating CNC instructions

Our skilled CNC programmers utilize Mastercam, a PC-based CAD/CAM software, for efficient and rapid turning and milling operations. Throughout this stage, we continuously explore opportunities to optimize the design for enhanced production efficiency.

3,CNC manufacturing
By following the instructions of CAM software, we meticulously manufacture parts using CNC milling machine centers. Our production lines are equipped to handle 2-axis, 3-axis, 4-axis, and 5-axis production capabilities. Whether it’s a straightforward dowel pin or a complex CNC turning-milling part, we have the expertise and resources to meet your needs.
How to Create a Custom CAD Drawing

CAD, which stands for computer-aided design (*Ref 1), is extensively utilized across various industries to enhance design efficiency and quality. One of the notable advantages of CAD is the ability to generate electronic files of drawings, facilitating seamless communication between designers and manufacturers. These files serve as comprehensive platforms, carrying all the necessary information for CNC machining service providers. Typically, we utilize CAD software to read, modify, and create 2D and 3D CAD drawing files, enabling us to work with precision and accuracy.


The Process of Generating a CAD Drawing

CAD software has revolutionized engineering modeling in industries such as automotive, aerospace, reverse engineering (*Ref. 2), PCB design, animation design, industrial design, and architectural design. Here are the general steps involved in creating 2D and 3D CAD drawings using CAD software:

  1. Conceptualize the design.
  2. Select the appropriate CAD software.
  3. Create a new drawing and set parameters.
  4. Sketch and draft the design.
  5. Apply dimensions and constraints.
  6. Create 3D models.
  7. Fine-tune and edit the design.
  8. Assemble components if needed.
  9. Assign materials and textures.
  10. Generate realistic renderings or animations.
  11. Create technical drawings for documentation.
  12. Save the CAD drawing in the desired file format.

How to Get CAD Software?

CAD software is a vital tool in CNC machining service projects, offering powerful capabilities. An ideal CAD program should enable both 2D drawing and 3D modeling. However, selecting the best modeling software across different market sectors can be challenging due to the variety of features available. The key elements of good CAD software include:

  • Comprehensive functionality
  • User-friendly interface
  • Accurate and precise modeling
  • Compatibility with various file formats
  • Efficient editing and modification tools
  • Robust rendering and visualization capabilities
  • Collaboration and sharing features
  • Adequate technical support and updates

There are numerous free CAD software options available for both personal and professional modeling needs. If you have any questions about CAD software applications, feel free to reach out to us via email.

What OVERLAND Need for Quote

Before submitting an RFQ (Request for Quote) to us, it is essential that you have your own 2D and 3D CAD drawings to clearly represent your project. Alternatively, if you have a physical sample and require reverse engineering, we can assist you in that process.

In addition to the 2D and 3D CAD drawings, it is the customer’s responsibility to provide detailed information for the RFQ project. Based on our core services, the required information can be categorized as follows:

1, CNC Machining Service

  • Material
  • Surface Finish
  • Batch quantity / Annual quantity
  • Other important notices for manufacturer

2, Other Services
     – Stamping

  • Material, including thickness
  • Surface Finish
  • Batch quantity / Annual quantity
  • Other important notices for manufacturer

– Plastic Injection

  • Material
  • Color
  • Surface texture
    Batch quantity / Annual quantity
  • Surface region allowed for inlet, venting, ejector pins
  • Other important notices for manufacturer

For long-term and large quantity production, we highly recommend utilizing plastic injection molds with multiple cavities. While this may incur higher tooling costs upfront, it results in significantly lower unit prices per part. With multiple cavities, more parts can be produced in a single shot, improving efficiency and reducing overall production costs.

– Die Casting

  • Material
  • Surface Finish
    Batch quantity / Annual quantity
  • Surface region allowed for inlet, venting, ejector pins
  • Other important notices for manufacturer

| Billet Cutting

Having well-prepared raw materials is crucial for efficient mass production and cost reduction. Our billet shearing machine can handle billet sizes ranging from 100mm square to 300mm square, enabling precise and efficient cutting. Billet cutting is a necessary step before CNC milling, as well as for manufacturing CNC turning components with rods larger than 65mm in outer diameter.

| CNC Programming

To ensure ease, productivity, and profitability in our fabrication process, we rely on the PC-based CAD/CAM software Mastercam. It enables us to streamline design, engineering, operation, programming, and machining, saving valuable time and maximizing efficiency in turning-milling fabrication.
