Applications and Implications
Assignment
Plan and
document a final
project
that integrates the range of units covered:
What
will it do?
They perform adaptation of a mechanism that can be used in almost any CNC-Router, this time going to work with AXYZ CNC router 4008; However, adaptation can work for any CNC Router just modify the base to place the router, which is to design and manufacture the basic principles of a knitter 3D kinematics. Similarly to perform a base fabric with hooks for 3D woven mesh is necessary.
Who's
done what beforehand?
In marginalized communities in Chiapas Tzotzil women are dedicated to developing rich colors woven fabrics and geometries applied in clothing and in everyday life and in quilts
These fabrics are made by means of tools and mechanisms made of wood and basic principles of kinematics and hand finished.
Adaptation to the CNC numerical control machine is intended as a first aid to develop these tissues by mechanical means, the final idea is to perfect progresivanete and provide each family a CNC Tzotzil of Chiapas communities.

* Epoxy resins
Where will they come from?
The motors will be purchased from a company called Robodacta bearings and a deposit of nonfunctional electronic objects in the university. The electronics are bought in DIGI-KEY and AG Electronics and materials manufacturing a container of scrap material that is told in the FabLab for students to leave and have the material in is, some of it will acquire in a wooden house called Masisa.
How much will it cost?
The approximate cost of the adaptation of the numerical control machine is 220 USD
What parts and systems will be made?
* Train rack and pinion gears and was applied in the thread tension
* Limit sensor and controlled for gearmotor designing control with a L293
* FabArduino to receive the signals from the sensors limit switches to measure and control the engine that will power the gear train.
*
Gear Train
What processes are used?
For
the preparation of the altered parts will be made in CNC Laser
cutting and CNC
cutting
For
the development of the electronic circuit boards the ROLAND
MDX MODEL 40A

Download files for eagle driver_for_gearmotor
What processes will be used?
Design the whole CNC programming to run GCode
Elaboration of calculating gear trains
Perfect design of the mechanisms.
Tablet design FabISP
CAD finish drawing the adaptation of the machine
CAM processing of all GCode
What
tasks need to be completed?
As originate a GCode to make it compatible with the geometry ofa handmade fabric?
Not resolved the realization of the threads tie knot, how?
As
I will design hooks weaver who caught the needle thread?
What is the schedule?
The date of preparation for the final project is 22 to May 29 with hours from 8:00 am to 10.00pm to meet all requirements of the adaptation of the CNC
How
will it be evaluated?
Assessing the Tzotzil women undertake when the project is completed individually CNC router for each house in the communities in Chiapas.
