CNC In Modeling And Prototyping


CNCs in Modeling and Prototyping
A CNC tool can be used in many ways for prototyping, reverse engineering and modeling.  As a rapid-prototyping tool, a OMNI can machine foam, wood, plastics and aluminum to efficiently create prototype and reproduction parts.  With a CNC tool, you will typically be doing subtractive prototyping, but it is a process that lets you machine quickly in materials that are similar to the end product.  Large projects can also be done using additive layering techniques that allow substantial models to be constructed even beyond the machinable area of the CNC.
The sheer versatility of a CNC wood router in a prototyping setting is nothing short of astounding.  With a good CAD/CAM package and a CNC router, it is possible to create master models with the proper draft for secondary operations such as casting, vacuum forming, sheet metal stamping and FRP composite construction.  These types of models are typically 2.5D, meaning that they don’t have undercuts and can be completely machined on a 3-axis CNC on one side of the material.  In addition, advances in affordable hardware and software now give you the ability to cut double-sided parts using 3 axes and carve true 3D parts on a machine equipped with a 4th axis, rotary indexer.  The indexer can be used as a lathe to cut simple profiled turnings or elaborate 3D parts and relief carvings, giving many of the advantages of a 5-axis tool at a fraction of the cost.
Mold Making
Aside from playing a key role in subtractive methods of creating models, the CNC is also instrumental in preparing molds for creating parts.  Thermoset plastic parts can be created in conjunction with a rotational molding machine.  Masters can be created on the CNC, molded and setup to produce thin-walled and hollow models not possible using a subtractive strategy. A CNC router coupled with the proper mold making equipment is a potent combination spanning many industries and applications.
Reverse Engineering Processes
While CNC wood routers excel at producing accurate parts with speed and efficiency, they also excel when it comes to reverse engineering an existing 2D or 3D part.  The digital version of the part can then be toolpathed to produce an exact duplicate, or transformed into an updated version by modifying the scale or geometry to create the required part. Using the optional rotary indexer, odd-shaped and cylindrical 2D & 3D parts can be digitized a full 360° with the same straight-forward method as a standard 3-axis tool equipped with a probe.

Use CNC Wood Router For Mold Production


Dianel Dean and Ryan use cnc wood router to produce a mold for their project " Underground Sound".  Their project is with some giant flowers, which allow people to hear the sound from earth via megaphones.

The mold for the megaphone was designed in Rhino and imported into Enroute software as an .STL. They created all the toolpathing in EnRoute. The form was cut in pieces on the CNC router mold using a 1/2" wide by 3.5" tall ball nose bit.  Daniel glued together panel board to be 3.5" deep and divided the megaphone up into various sections. Once cut, the sections were glued together to create the final form, which was then used as a mold for the fiberglass.


The following is the final project at field.

Programing standards for Variables

Now that we have defined functionality, we need to set some standards with regards to the macro programming. The first thing to consider is the variable table. You have four (4) types of variables:

Local Variables: These variables are local to the program. Normally used to transfer values to a cycle call, or as intermediate mathematical value holders. I hate using local variables because of one major issue with them. They are reset to null (not 0) when the control is reset or the program ends. While perfectly fine for use in transferring variables to canned cycles, etc. They can get you in trouble if you use them for other things. I, just by policy, never use them for anything. In Fanucese, these are typically #100-#499 (if you have that many available). Local variables are only available to the program in which they are used.

Global Variables: These variables, once set, remain set unless you change or reset them via macro or the control keyboard. Unlike local variables, global variables are available to any program in the control. I use gobal variables because they are retained, can be used in any program, and you can track what's going on if you have an issue. In Fanucese, these are typically #500-#999

System Variables: These variables are available to use in macro programming and allow you to write and retrieve information from the control itself, such as tool in the spindle, tool offset active, write and read offsets, check active codes, etc. Very handy indeed, BUT, these are _NOT_ standardized to a great extent. You will have to consult the macro programming portion of your control manuals to determine what these are.

String Variables: String variables are a group of characters interpreted as a single value. Typically defined with a $ symbol. String variables allow you to manipulate text and phrases etc. Not all controls support string functions.

I typically define my variable fields along the following lines:
#500-599 : Input variables to the macro
#600-799 : Mathmatical functions of the macro
#800-899 : Variables needed with regard to tooling, offsets and system variables.
#900-999 : Logic keep bits, counters, etc

Macro Programming Fundamentals

Macro programming is a useful tool for most any CNC machine shop, whether a one man garage or an international conglomerate. Macro programming provides a means of shortening code and doing repetitive tasks easily and quickly. All of your canned cycles in a control are nothing but a macro. Macro is also extremely useful for families of parts.
All computer programming is on a fundamental level, very similar. The syntax of the commands, and purpose of the programming may change, but the fundamentals of how to approach it, how logic works, and program flow are pretty much the same.

The first step to any programming is to define the _functionality_ required of the program. Functionality is defined as the end result(s) and abilities expected of the computer code. In other words, what is it supposed to do.

When we write a macro, we have a desired result in mind. Write down the broad-based result you are looking for from the program. A broad-based result would be something like: Bolt circle drilling, rectangular pocketing, block facing, slotting, etc.
For an example, lets use bolt circle drilling.
After we have defined the broad-based functionality, we need to narrow down the specifics of what we desire from the program. We must set limits to the functionality we want to achieve. If no limits are set, then the program becomes too large, cumbersome and time consuming.
In our example, one of the main limits we need to set is the maximum number of holes we will be allowed to drill in the macro. For the sake of brevity, lets limit ourselves to 10 holes (We have another question coming up that, in reality, allows unlimited holes using only 10 as a maximum here)
So: Max Holes in pattern == 10.
Next up on the functionality list regarding hole drilling: Do we have a drilling cycle in the machine control or not? Most of the time, this is going to be a yes, so we will go with that.
So: Have drilling cycle in control == Yes
Next up on the functionality list: Do we want the ability to start the hole pattern at some angle other than directly along one of the major machine axis (X,Y,Z), this is seen often in parts, so yes, we want this functionality.
So: Ability to start holes at operator input angle == Yes
Next: Do we want the macro to call the tool, or will you already have the tool in the spindle when you call the macro? Lets do macro does not call tool. This is really a programmers preference as to which way to go, but since the possibility exists that we could do multiple bolt patterns with the same tool, we wouldn't want to go to tool change position each time between patterns.
So: Macro calls tool == No
Next: Do we want to induce multiples of our max holes? This would allow you to drill more than our stated maximum number of holes. I think we can implement this in a short manner, so we will do this.
So: Macro allows multiples == Yes
What other functionality should we define?......hrm.....for now I can't think of anything, so onward we go with the functionality described above.

3d printing with UV light curing resin

Phantom Geometry from Liz and Kyle von Hasseln on Vimeo.




This is ‘Phantom Geometry’, a masters thesis in architecture by Kyle von Hasseln and Liz von Hasseln, developed in the Robot House at the Southern California Institute of Architecture (SCI_Arc). It was awarded the inaugural Gehry Prize at the SCI-Arc commencement ceremony on September 9.

This work is centered on the development of a system for generating material volume from streaming information. The system uses UV light from a modified DLP projector to continuously and selectively cure photo initiated resin within a shallow vat system we developed for the project. The cured part is simultaneously and continually pulled away from the vat, allowing un-cured resin to flood in beneath it to be subsequently cured. The result is the material reification of streaming data that emerges along the motion path of the Staubli robot maneuvering the vat/projector apparatus.

This system of fabrication relies upon native real-time feed-back and feed-forward mechanisms, and is therefore interruptible and corruptible at any time. The streaming data input may be transformed or modified at any time, and such interventions impact emerging downstream geometry.

Rostock MAX

Currently on Indiegogo




From their IndieGoGo page:

Advantages of the Delta Arm design:

  • MUCH faster Z axiz movement.  A traditional 3D pritner design uses threaded rods or acme screws.  These severely limit the Z axis speeds to about 200-400 mm/min speeds.  With the Rostock MAX, we have the same speed in X/Y as we do in the Z, which is up to 40000 mm/min.  Holy Cow right! 
  • Counter acting forces of movement.  With a traditional pritner again, you have a carriage moving left/right or front/back, and it has to overcome the weight of that movement to reverse it's direction.  We use accelaration to tune the motors DOWN to slow the speeds of the carriage when it's near the end of a move so it doesn't "whip" or chatter, when changing directions.  With the MAX, all three carriages have to move together to make coordinated motion, so if one arm has to go up, the other two have to go down, and this cnacels out a huge amount of the inertia in the movement at the head, so we can tune the motor to a much higher rate, increasing the speed.
  • Circular motion is smoother by default with the Rostock MAX.  The delta arms also have a unique feature, SUPER ROUND CIRLCES!  Now, yes, you can have the same smooth circles with a standard printer, however, you have to work to get it to make those circles very round.  The reason is you have two straight lines, one in the X and one in the Y, and you have to vary those two lines to make a circle.  Any backlash in the belts/pulleys etc... will cause the circles to come out egg shaped at best.  With the MAX, circles are more true, becuase any backlash that could exist is cancelled out by the fact that the platform "hangs" from the arms, and gravity takes care of the rest.  There are other reasons too, such as that every single move sent to the printer is split into 200 seperate movements.

Features:

  • Approximate 10"+ Diameter x 13" + High build volume
  • Sturdy design using bolted together parts
  • Precision laser cut, CNC and injection molded parts
  • Designed for english OR metric hardware
  • Windows, MAC, and Linux compatible with OS software
  • Uses UltiMachine RAMBo electronics
  • Uses Standard NEMA 17 motors and GT2 timing belt
  • 15 Tooth motor pulleys
  • Filament is held by the machine, no more tangled spools on the floor
  • Wide open access to the build area, easy to get at parts
  • Unique design lends to easy modification for other uses
  We are looking into other "tool heads" to attach to the platform.  Some easy to convert ideas are pick-and-place vacuum head for electronics board assembly, sodler paste syringes for PCB prepping, pen mount (it's the $25 perk) for plotting/drawing and even a low power laser platform should be easily adaptable.
***EDIT***
 We are also going to be using UltiMachine's new electronics boards, the RAMBo. They have the ability to run two extruders, one heated bed, and up to 5 stepper motors.  Check out theRAMBo wiki page to learn more about these really awesome 3D printer electronics from UltiMachine.  The boards have 5 allegro A4984 stepper drivers, two plugs if you ever need a dual-z motor setup etc..., 4 thermistor inputs, and so many more awesome features. 

More information about our Rostock MAX can be found online over at theRepRap project, as well as our Forum.  We will be posting build instructions, CAD files, firmware settings and more, all on ourRepRap.org Wiki Page


Filament makers

Usually if you want to print something you need to have filament to feed your 3d printer. But, what if you could recycle your failed models or even recycle waste plastic and make f3d printing filament out of it? Basically suitable junk plastic is ground up, continuously pressed and melted trough extruder similar to the one on 3d printer and after cooling you get filament ready for next print job.  Currently there are two projects that I know which are developing usable technology. They are in various stages of development and availability, let's hope that this technology goes into full implementation. 


Filabot 

From filabot.com :
Filabot is a desktop extruding system, capable of grinding various types of plastics, to make spools of plastic filament for 3D printers. Not only is it user friendly, but it is also environmentally friendly. The Filabot can process things such as: milk jugs, soda bottles, various other types of plastics, and bad prints, to make new filament for a future print. Filabot will bring the real power of sustainability to 3D printing, allowing for a one stop shop to make anything.



Lyman Filament Extruder 

From http://www.thingiverse.com/thing:30642 :
The Lyman Filament Extruder is a machine that extrudes filament from pellets for use in a 3D Printer. It can extrude 1.75mm and 3mm filament with easy nozzle exchange. The material cost is about $250.
On their thingiverse page there are plans, files and guides available.

3d printing DRM patented

Here we go again with all the DRM stuff. 3d printing DRM is patented. When will they figure out that patent system is broken and DRM does more harm than good? From the looks of it, the guy is just setting up generic patent so he can potentially patent troll future 3d printing DRM system proprietors.

Article summary:

Sometime in the none-too-distant future, replacing your favorite coffee mug or creating a new iPhone case might be as simple as downloading a design you like from the Internet and firing up your 3-D printer.
Most 3-D printing has been done in industry or by hobbyists who share their designs freely online. Now Intellectual Ventures, the company run by Nathan Myhrvold, the former Microsoft CTO and alleged patent troll, has been issued a patent on a system that could prevent people from printing objects using designs they haven’t paid for.
The patent, issued Tuesday by the U.S. Patent & Trademark Office, is titled “Manufacturing control system” and describes methods for managing “object production rights.”
The patent basically covers the idea of digital rights management, or DRM, for 3-D printers. It also covers using digital files in extrusion, ejection, stamping, die casting, printing, painting, and tattooing and with materials that include “skin, textiles, edible substances, paper, and silicon printing.”
Control schema: A drawing from a patent won by Intellectual Ventures describes how to control digital rights for 3-D printing.
“This is an attempt to assert ownership over DRM for 3-D printing. Myhrvold’s operation, based in Bellevue, Washington, basically exists to file and buy patents, and currently controls nearly 40,000 of them, according to a spokesperson.
The manufacturing control patent, number 8,286,236, was filed back in 2008 and issued on October 9 to Invention Science Fund I, an arm of Myhrvold’s company.

Choose What To Cut Aluminium


How to cut aluminum? By China CNC Router or waterjet? Sheet size would be 4' x 10' with a thickness of 1/4-1/2". Such aluminium is for fabricator, many companies use plastic and wood laminates. it would be a better investment for the company to buy a machine that could do multiple things as opposed to a water jet or china cnc router which will only cut steel and aluminum.

You can cut aluminum with a china cnc router. The China cnc router needs to be set up with lubricant spray and the vacuum pump cannot be one with graphite vanes - if the lubricant sucks through the vacuum to the pump and gets on the vanes, they are toast. Routers are not really made for cutting metals, however, the key word above is "can." For working metal, it is better to get a mill, as they are engineered for metal work in terms of feed rates, rotation speeds, adequate lubricant flow, recycling lubricant, etc. Hold downs are usually mechanical using t-channel (rather than vacuum, as is typical on  China CNC routers). Routers' rotation/hp ratio are typically best at higher rotational speeds (like 18,000 to 21,000 RPM), which are way higher than those normally used for metals. I have been doing aluminum on our China CNC router.
