Computer – controlled machining

Something big

this chapter we develop some large object with a CNC machined

cut router, the experience was intense, very clear learning the

use of tools, programs and techniques to achieve good results,

the development here:

Computer – controlled machining

STAGE ONE: to draw the Plan of Pieces

to start cutting, it is necessary to develop a parts plan, where We

could place 2D vector drawing and the parts will be cut first made a

freehand drawing of the shape and the cutting path, since my design

had low relief and cut into the same parts.

To draw a sketch first start recognizing the steps I should follow for cutting, bit rate, measures of the platform, machine type and brand: Shopbot, the program features: Partworks, after a few classes at the Lab, I assembled the sequence of work.

To draw a sketch my work had a particular characteristic, large pieces had a configuration and other small parts, plus the material thickness and type of strawberry were different in each case. We also had to check the court order and low relief, in conclusion I had to draw a route by cutting and beware performed each file.

To get a correct Tolerance one of the main activities before the court is to prepare the correct tolerance assembly pressure on the union of two pieces, for this I made many tests looking for the right measures assembly, I did a piece of example 4 sides each with measures different, so I could get the right

To draw in 2D program first start recognizing the steps I should follow for cutting, bit rate, measures of the platform, machine type and brand: Shopbot, the program features: Partworks, after a few classes at the Lab, I assembled the sequence of work.

Fit the pieces my project is to cut 16 boards and 16 boards frame background, background are of low relief to fit a few buttons. It also has holes to put bolts. This work began with a prototype where he performed the calculation of accuracy measures and distances, all parts are repeated but should be totally perfect.

STAGE TWO: to make it in PartWorks

Partworks Is a simulation program of the Shopbot CNC Router, this

program is my easy to use, we must configure each cut file, place the

measures and correct locations, then save the file to bring it to the

cutting machine.

Open the Software, Load file, select file, open file and put in the correct cordinate.

when the file is placed in the correct coordinates, we must select the type of cut: low relief or full cut. Then we can visualize the journey that makes the drill as a cutting simulation

STAGE TWO: Shopbot Console

this part of the development is very important, concentration,

calculation to handle the machine, use the right tools and

accessories, cutting a router must be prepared properly, then we will

see good results (;

to start we calibrate the X, Y and Z of the machine, proceed to the menu icons or shortcut icons. We read every message that the program shows, we also place the calibration fixture plate every time we start a new cut.

once the axles are already configured we can open the file in *.spb each type of cut set. Before we turn on the filter and ensure equipment is fit to begin the cut.

open the file after the machine starts the cutting path, pressed the green button and follow the instructions on the command console. Throughout the court must have the correct ear protection and goggles. For any situation we pause press the red button or pause the cut

STAGE THREE: To assembly the pieces

after cutting the fun begins;) going to put all the pieces according to

the design, we have already made an initial prototype, then the

pieces should fit perfectly, or at least I hope (;

I had to get a technique armed for this furniture, I started listing each piece, looking for your correct address, each was setting in its base from Part 1 to Part 16. then you have all the set pieces, you need to use the hammer rubber to secure.

This job lasted about 4 hours, between selecting the pieces, sand and place them in their correct position, plus set with the hammer, I got the help of a partner to place the top of the circular structure.
