3. Computer controlled cutting

Group assignment:

  • Characterize your laser cutter's focus, power, speed, rate, kerf, and joint clearance.

To see our group assignment click here

Individual assignments:

  • Design, lasercut, and document a parametric press-fit construction kit.
  • Cut something on the vinyl cutter.

Creating an Assembly Part with the Epilog Laser: Fusion Edge

Overview

Logos

This guide explains how to design and manufacture an assembly part using Inkscape, AutoCAD, and an Epilog Laser.

I will explain my press fit kit design and fabrication i also design other projetcts,

Step 1: Create a New Part

  • Open SolidWorks.
  • Select the Part option.

Step 2: Create a Sketch

  • Click Sketch.
  • Then click Sketch.
  • Select a plane.
  • Choose the Circle tool.

Step 3: Draw the Geometry

  • Draw a rough circle without worrying about its radius.
  • Click the arrow next to the Line tool.
  • Select Construction Line.
  • Start from the bottom of the circle and draw a construction line through the center.
  • Draw another construction line perpendicular to the first one.

Step 4: Create the Global Variables

  • Click Tools.
  • Select Equations.
  • The Equations window opens.
  • Draw two lines parallel to the second construction line.
  • Enter the required parameters.
  • Click OK.

The parameters used are:

  • scal
  • kerf
  • thickness

Step 5: Apply the Dimensions

  • Select the Smart Dimension tool.
  • Click the two lines created previously.
  • In the Edit Dimension window, type:
= "thickness" - "kerf"

or

  • Click Global Variables.
  • Select thickness.
  • Click -.
  • Select kerf.
  • Confirm.

Repeat the same operation between the bottom line and the center construction line to ensure symmetry.

=("thickness"-"kerf")/2

Step 6: Dimension the Circle

  • Repeat the same procedure for the circle.
  • Use the scal parameter.
  • Enter the desired diameter and its unit.
  • Mark the desired opening on one side.
  • Select the Line tool.

alt text


Step 7: Mirror the Geometry

  • Click Mirror Entities.
  • Duplicate the shape.
  • Select Smart Dimension.
  • Enter the width of the opening.

alt text


Step 8: Trim the Sketch

  • Click Trim Entities.
  • Remove all unnecessary construction lines.
  • Save the file in DXF format.

Cutting Preparation

Step 9: Open Inkscape

  • Open Inkscape.
  • Create a new document.
  • Drag and drop the DXF file into the workspace.

alt text


Step 10: Prepare the Layout

  • The part appears in the workspace.
  • Press Ctrl + D to duplicate it as many times as needed.
  • Click File.
  • Select Print.
  • Choose your cutting machine.
  • Click Print.

alt text


Step 11: Start the Cutting Process

  • The cutting interface opens.
  • Enter the required settings.
  • Click Print.
  • The cutting file is sent to the machine.
  • Press the Start button to begin the cutting process.

Step 12: Final Result

  • Once the cutting process is complete, remove the pieces.
  • Assemble them as desired.

Step 1 : Image Preparation : download the map image from Google

  • Open Google  
  • Choose an image   Choose a picture

Step 2 : Vectorization with Inkscape

A Import Image from folder to Inkscape

  • Open Inkscape   Import into inkscape

B Convert to Vector

  • Go to Path → Trace Bitmap   Formatting 1

C Clean the Image

  • Remove the background   Formatting

D Create Assembly Features for contrain making

Partitioning


i can cut but i have to make a parametric , so that continue with AUTOCAD

Step 3 : Processing in AutoCAD

Import & Duplicate

  • Import your file  
  • Use copy tool → create 5 identical shapes  

Adjust Geometry

Partitioning 2 Partitioning 3


Step 4 : Understanding Clearance

A - What is Clearance?

Clearance is the space between two parts to ensure proper assembly.

Type Description
Clearance Fit Easy insertion
Zero Fit Perfect adjustment
Tight Fit Forced assembly

B - Practical Case

  • Base length: 1.77 cm  
  • Laser thickness: 0.2 mm this is our laser cutter kerf
  • Adjustment: +0.1 mm  
  • Final clearance: 0.15 mm

Step 5 : Final Check in Inkscape

  • Set stroke width to 0.2 mm

Formatting 2 Import for cutting


Step 6 : Epilog Dashboard Setup

Import for cutting 2


Step 7 : Cutting Parameters (3mm MDF)

Parameter Value
Speed 30%
Power 100%
Frequency 100%
