The ultimate quality of a cut, whether laser or industrial, does not depend solely on the skill of the operator and the advanced device. Much of this quality goes back to a stage before starting the work: Preparation for Cutting Pattern . A perfect, precise and standard file is the cornerstone of a perfect output. Many common problems such as inaccurate dimensions, rude edges, increased cost and time loss are rooted in an inappropriate design file. For this reason, mastery of important points in preparing the template for laser and industrial cut are an absolute necessity for any designer, engineer and manufacturer.

Collection Dena Cutting as one of the leading centers in laser and industrial cutting services in Tehran, works daily with dozens of template files from different customers. We've seen closely how a cutting file can accelerate the process and improve the result dramatically, and on the contrary, a weak file can re -work and impose extra costs. In this comprehensive guide, we are going to provide you with all your experiences so that you can prepare your files for each shear and get the best results from our services.

Why is the proper preparation of the pattern file so important?

Laser cutting machines and CNCs (industrial cuts) are precise machines that take their commands directly from a digital file. They cut exactly what is designed in the file, without any shortcomings. So:

Dimensional accuracy: If the dimensions in your file have even one tenth of a millimeter error, the final piece will have the same error. Preparation of the pattern for cutting guarantees that the components are produced exactly in accordance with your needs.

Decreased waste: A optimized file with proper nesting can minimize the amount of material outburst and reduce your costs. Clean and without additional lines, the device speeds up the speed of the cutting process and thus the total speed of the cutting process.

Prevent unpredictable errors: open lines, or additional nodes in the file can stop the device, make incomplete cuts or even damage to the material. Cutting Standard to the Service Center makes the price query process faster and more accurate.

Part One: Basic Tips in Cutting File Design

These are the basics that must be observed for any type of cut (laser or industrial) and any software.

1. Select the correct file format: the common language with the cutting machine

Cutting machines accept specific formats. The most common and standard formats are vector formats that store the lines based on mathematical equations and do not lose quality by magnifying.

Suggested formats (in order of priority):
- DXF (Drawing Exchange format): The Golden Standard of the Industry. Almost all CAD software and cutting machines support it. This is the best option for transferring files between different software.
- DWG (AutoCAD Drawing): Native AutoCAD software format that is very common and reliable.
- ai (Adobe Illustrator): Format is appropriate, provided the final output is properly prepared.
- CDR (Coreldraw): Corel Draph software format that is very popular in Iran.
Inappropriate formats: BMP (pixel files): These files are not suitable for cutting because they consist of pixel, not math lines. Of course, they can be converted to vector, but often lose accuracy.
PDF: Although PDF may contain vector, it may also include additional information (such as unnecessary images and texts) that complicates the process. It is best to send the original vector file.

Key Note: Always save your file in one of the original vector formats such as dxf or dwg

2. Scale (SCALE) 1: 1 and the correct measurement unit (millimeter)

This is one of the most common causes of error. Your design should be designed exactly the size you want to cut (scale 1: 1). If you need a piece of 10 cm in length, you should draw a line of 100 mm in length.

Standard Unit: The standard unit in the cutting industry is mm (mm) . Set all your dimensions accordingly.
Final Review: Before submitting the file, check one of the main dimensions of the design with the software measurement tool to make sure the accuracy of the scale.

3. Remove all additional and unnecessary elements

Your Cutting File should be completely clean. Only the lines that are to be cut must be in the file.

Items to be deleted:
- Dimensions: Identify these lines as a cutting path.
- Texts, descriptions and logo: ).

a clean file results in a clean cutting process.

4. Ensure that all paths are closed (Closed Paths)

To cut a complete shape (eg a circle or square), the path must be completely closed. An open path (for example, a bow instead of a full circle) causes the cutting machine to drop at a point and create an incomplete shape.

How to Check? Most software have a tool for connecting the end points or detecting open paths. Use these tools to make sure all the forms are closed.

5. Remove the lines (overlapping lines) and duplicate

If the two lines are exactly together, the machine will cut that path twice. In addition to wasting time, this causes excessive burns to the edges in laser cutting and double pressure on the blade in industrial cut .

Useful Tools: In software such as AutoCAD, use the Overkill command to automatically remove all lines and forms of repetition. This command is one of the most important tools in preparation of the template file for cutting .

Part Two: Advanced Tips for File Optimization

These tips help you go beyond the basics and make a fully professional and optimized file.

6. Using Smart Layers

If your file contains various operations such as Cut, Engrave/Score, and Marking, use layers to separate them.

Practical Example:
- Cut layer (cut): All lines that must be completely cut. (For example in red)
- Encrave layer: All surfaces that need to be engraved. (For example in blue)
- Score layer (line up): All lines that need to be laser -powered to create lines. (For example with yellow)

This helps the device operator in Dena Cutting Collection to quickly and accurately apply the settings of each operation to the relevant layer.

7. NESTING Optimization to Reduce Thrinking

Optimal layout of parts in a sheet or sheet of material is called "nesting". A good nesting reduces your costs directly.

Network Tips:
- Distance between Parts: Do not close the pieces too close together. A minimal interval (usually equal to the thickness of the material or at least 2-3 mm) is needed to prevent damage to the adjacent piece.
- Use Common-Line Cutting: If two rectangular pieces have a common edge, you can cut them with one cutting edge. This will save time and money.
- rotate the parts: rotate the parts to find the best puzzle-like layout and fill the empty spaces.

In the Dena Cutting Collection , we also provide layout optimization services, but providing a good basic wetter file will speed up work.

8. Control the number of nodes (nodes) in curves

The curves in the vector files consist of a set of points or nodes. Excessive nodes cause the device to move and shake the device and cause rough edges.

Solution: Use "Simplify" or "Smooth" tools in your software to reduce the number of extra nodes without the original curve deformation. A soft curve will have a better result.

9. Note the minimum thickness and details of the cutable

Each device and each material has a limit to a minimum cutable thickness. The design of a very thin line may not be implemented in practice or the final piece is very fragile.

Fetal Law: As a general rule, the minimum thickness of one part of the piece should not be less than half the thickness of the material itself. Always consult with the cutting service center (such as Dena Cutting before finalizing the designs.

Final checklist before sending file to "Dena Cutting"

Before pressing the "Send" button, review this list:

Is the file format DXF or DWG?
Is the design scale 1: 1 and its unit is millimeters?
Have all the extra lines, measurements and texts been deleted?
Are all paths and forms closed? (Join command)
Has all the lines been removed? (Overkill command)
Are different operations (cutting, engraving) in separate layers?
Is the layout of parts to reduce optimal outflow?
Are the curves soft and with the number of nodes?

Observing these tips may seem time -consuming at first, but in the long run it will save a lot of time, cost and energy and guarantee the quality of your final product.
