Possible Testing Procedures (Will be Updated)

Introduction:

A CNC router is a system that requires the ability to cut 4’ x 8’ pieces of wood and fold and move for storage. The machine precisely cuts wood using a computer to transmit data.

The material bed, linear motion, motors, and software will be tested. The final testing procedure will test the entire system as a whole.

The designer will test each step in the process.

The testing takes place in the systems lab. The lab’s conditions relate to the outside conditions. On average, the lab’s air contains a high salinity and humidity reading.

a.       Wires to motors from computer

b.      Plug in router

c.       Plug in computer

2.      Use Volt and AMP tester to check electrical flow.

3.      Process a design file through all three softwares.

a.       Turn CAD into CAM file

b.      Open CAM in the controller

c.       Submit to machine

4.      Check machine for completion of the design file.

Testing Type: Assessment and Validation

Testing Stage: Quaternary

State of Solution:

            On

            Stationary machine

            Moving rails and bearings

Condition of Testing Stage

            Lab environment

            During construction

Tools and Equipment Required:

·                           Completed CNC machine

·                           Drawing Files

·                           Controller software

Testing Procedures:

1.      Run different drawing files through machine to test for alignment and precision.

2.      If not accurate, tweak setting in controller software to allow for backlash and machine habits.

3.      Test files until the machine produced completely aligned products.
