Week07-computer-controlled machining

Group assignment:

Complete your lab’s safety training
Test runout, alignment, fixturing, speeds, feeds, materials and toolpaths for your machine
Document your work to the group work page and reflect on your individual page what you learned

Individual project:

Make (design+mill+assemble) something big

Linked to the group assignment page
Documented how you designed your object (something big)
Documented how you made your CAM-toolpath
Documented how you made something BIG (setting up the machine, using fixings, testing joints, adjusting feeds and speeds, depth of cut etc.)
Described problems and how you fixed them
Included your design files and ‘hero shot’ of your final product

safety

Wear appropriate personal protective equipment: Operators should wear suitable personal protective equipment, including safety glasses, earplugs or earmuffs, protective gloves, and appropriate clothing.
Equipment inspection: Check the status and working conditions of the equipment before each use. Ensure all safety devices and protective guards are in good condition, such as emergency stop buttons and protective covers.
Safety area: Ensure there are no debris or obstacles around the work area to ensure the safety of operators and other personnel. Maintaining a clean work environment can reduce the risk of accidents.
Operating procedures: Follow the correct operating procedures and safety standards. Do not violate the guidelines or instructions provided by the equipment manufacturer.
Materials and tools: Use the correct materials and tools for processing and ensure they are in proper condition. Worn or damaged cutting tools and fixtures may increase the risk of accidents.
Monitor operations: Stay alert during equipment operation and be vigilant for possible hazards or abnormal situations. Take corrective action promptly and stop the equipment when necessary.
Regular maintenance: Regularly inspect and maintain CNC equipment, including cleaning, lubrication, and replacement of worn parts. Regular maintenance ensures the stability and safety of the equipment.
Emergency stop procedure: Ensure all operators know the location of the emergency stop buttons and understand how to use them correctly in case of emergencies.
Safety records: Record all accidents and safety incidents and conduct investigation and analysis to identify and correct potential safety risks.Wear appropriate personal protective equipment: Operators should wear suitable personal protective equipment, including safety glasses, earplugs or earmuffs, protective gloves, and appropriate clothing.
Equipment inspection: Check the status and working conditions of the equipment before each use. Ensure all safety devices and protective guards are in good condition, such as emergency stop buttons and protective covers.

Dog Chair Design

I saw a similar design on a social platform, and my girlfriend really loves dogs. So, I decided to make a dog chair for her.

I will use Fusion 360 to model my dog chair.

I used the rectangle command to create a model of the dog chair.
