- Auxiliary desk
- Dimensions
- Materials
Assigment development
- Design and produce a OSB board auxiliary desk, using a CNC machine
Dimensions
- Top: 30 cm diameter
- Height: 62.50 cm
- Depth: 40 cm
Parts
- Top: 01 circle, 30 cm diameter, two nochs 50° and 230°
- Leg: 02 L Legs, 62,50 cm long, with a noch at 50 cm
- Support leg: 02 support, 38 cm long
- Support: 01 circle support, 12 cm diameter, two nochs 50° and 230°
Define the product
- We used onhand materials
- We wanted to view the protoype, views and dimensions
- We focused on form, measure and functionality
- Dimensions double check
Materials
- Cardboard
- Jigsaw
- Pencil
- Ruler, compass
- Compass
Working on raw materials at homecenter
Define the materials for prototyping
- Evalue materials: MDF, OSB, Triplay and others boards. Thickness: 12, 15, 18 mm
- Coordinte cutting service: board dimensions. Considering the CNC machine
- We visited a homecenter for ideas
- Consider limited time
- Money constraint :) :) :) :)
- Transportation
Homecenter visit: we evaluated different materials, considering the price, dimensions, thickness and others
Different materials: MDF, OSB, Triplay and others boards. Thickness: 12, 15, 18 mm
OSB board, 18 mm thickness, 244 cm x 122 cm dimensions, tolerance: ±0.3 mm, define angular and flatness tolerance
Cutting OSB board, considering the dimensions of the board, the cutting area of the CNC machine and the dimensions of the parts.
Final pieces, ready for CNC machining, considering the dimensions of the board, the cutting area of the CNC machine and the dimensions of the parts
Working on design
Digital product design
- Design - Digital model in Rhinoceros 8
- Define desk geometry was defined, considering the prototype and assembly logic
- Measurement - Adjusting considering a 18 mm OSB board
- Preparation - Cutting and assembling the parts with Autodesk Fusion 360

CAM Programming for CNC
Manufacture workspace
- Prepare the CNC machine process
- Define: material, system selection, origin position, tool selection, toolpath generation, cut simulation, CNC export code
Material setting: OSB board, 18 mm thickness, 244 cm x 122 cm dimensions, tolerance: ±0.3 mm, define angular and flatness tolerance
Route: The toolpath was generated by following edges of each contour, and different parameters. Area clearance: 6 mm, step over: 3 mm, depth per pass: 6 mm, feed
Height and connections: Z Axes settings: tolerance 1 mm
Parameters: Gap 4 mm, free space: 9 mm, advance: 4 mm, back 4mm for the top and support circle, 2 tabs for the legs and support legs.
Parameters quality, tolerance 1 mm for the top and support circle, 2 tabs for the legs and support legs.
Parameters quality, tolerance 1 mm for the top and support circle, 2 tabs for the legs and support legs.
Parameters: cutting depth 6 mm and angle 2°
CNC simulation: the toolpath was simulated to check the process, and adjust parameters if necessary.
CNC simulation: the toolpath was simulated to check the process, and adjust parameters if necessary.
CNC simulation with different projects: the toolpath was simulated to check the process, and adjust parameters if necessary.
Exporting CNC code: the CNC code was exported to be used in the CNC machine, and cut the parts of the auxiliar desk.
CNC monitor with all the paremeters and settings for the cutting process, and the CNC code to cut the parts of the auxiliar desk.
