MP1 Update

Marking Period 1 entails my research into my background, alternate solutions, final solutions, testing procedures, models, and developmental work. As I proceed into Marking Period 2 I will finish developmental work and continue to finalize my drawings and begin to order parts.

Currently I am in the middle of my plan of procedures that consists of the bill of materials and assembly. I will have to finalize this before I complete my exploded drawings.

Possible Parts List with Links to Resources:
  • Wood:
        • Drivers: Gecko G540 4 Axis Driver
        • Breakout Board
        • E- Stop
        • Power Supply
        • Power Switch
        • Outlet Plug
    • Wires: Probably just an extension cord

Background Information


Self-manufacturing is a difficult and a costly process. Buying industrial machines costs thousands of dollars. A DIY machine greatly decreases cost and allows customization to fit the work environment. Designing a machine allows building a machine to fit niche needs possible.
Systems lab
Hobbyists and home owners represent the population that utilizes machinery in the home and small workshop environment. Factories require industrial made machines due to the workload present. Industrial machines require stronger materials that withstand ware. Home built machines can be made with cheaper parts due to the lack of stress on the machine. This cuts down on costs.
Industrial CNC MachineCited from: http://www.multicam.com/routers.html
The country is deeply engrained in industrialism. The general person buys mostly factory made objects. People want to manufacture within their homes. Home built machinery allows this. The ability to produce goods in the home is new to modern society.

Hobbyist and small business owners outsource technologically advanced and niche products. People look for the ability to self-produce. People with the intentions to manufacture products individually need machines that work in a small home or business environment. Designers feel innovated and inspired by the possibility of self-production.
            Home built machinery covers a wide range of products. Computers, CNC machines, and 3D printers represent a small portion of home built machinery. The machines allow customization to fit the needs of the users.
Home built computer
Small scale manufacturing requires money and utility space. Home built machines provide a way to make home manufacturing possible. Hobbyists with limited space build within the limit of space at home. Personal designed machines give hobbyists the ability to customize machines to fit needs. Ease of design and assembly concerns potential builders.  

Design Brief

One will design and produce a CNC router that presents the opportunity for students to cut precise material in the systems lab allowing students to create, design, and produce products for assigned projects.

Executive Summary

People are looking to self-produce in homes, schools, and small business environments. A CNC router solves this problem. The non-industrial design allows for easy storage and placement into different work spaces.  The machine’s purpose is to provide a way for people to manufacture wood and other soft material products.  The router can precisely cut materials into finished products or molds. One uses a CNC router by imputing a computer drawing into the controller software. The machine processes the file and cuts out the desired material.

A CNC router consists of a material bed, gantry, linear motion, motors, and computer software. The parts chosen determine how precise the machine cuts. The material bed supports the cutting material and contains the gantry, linear motion, and motors. Linear motion is the rails and bearings along with the motion drivers. Motors attach to the drivers that attach to the computer. The router attaches to the gantry that glides along the rails to change position.  Hinges applied to the material bed allows the machine to fold for storage. This allows the machine to be larger and still fit into a smaller area when not in use. Wheels attached to the table supporting the material bed allow maneuverability.

Storage and maneuverability is important when working in small spaces. People intend to use the machine for personal production. Space is important in limited work environments. Teachers need the ability to produce projects for shop classes. Industrial CNC machines in factories create modern day products. A small-scale machine provides industrial grade products in a small setting.

Many parts make up a CNC router. Teachers and students benefit from a custom router that fits in the systems lab. Students previously learn computer drawing before entering systems engineering. The students can make systems projects using previously taught skills. Teachers benefit from new possible projects that require the router. CNC routers bring production into small working environments.
