===Be Professional===
This commandment has two sides to it. It covers the idea of acting like professional (which Webster’s defines as “exhibiting a courteous, conscientious, and generally businesslike manner in the workplace”). The term also describes the standards of education and training that prepare members of the profession with the particular knowledge and skills necessary to perform their specific role within that profession. Hopefully, you are learning both of these as part of your education at George Fox University. In the Welding Lab we expect you to develop as a courteous, conscientious, and skilled craftsman, understanding the tools and equipment in the Maker Hub and how to use them effectively.

Welding is the process of joining metals together. It is a form of additive manufacturing. There are several different types of welding, and the Welding Lab uses most of these including spot welding.  
+
Machining is the process of removing material so it is subtractive manufacturing. We have a variety of machines in the shop.  
  
In the Welding Lab, metals are joined together using MIG (Metal Inert Gas), TIG (Tungsten Inert Gas), Stick and spot welding.   
+
The 3 main processes include milling, turning, and drilling.   
  
Each welder has its own special purpose and benefits.  MIG is fast and much easier to learn than TIG welding. Spot welding is only used with sheet metal. TIG welding produces very clean welds and the heat is more confined to a smaller area. TIG will also allow you to weld very thin metals.  
+
Each machine has its own special purpose and benefits.  The drill press will produce holes quickly but normally has less precision than using a milling machine.  The lathe is normally used for making round parts and drilling. The metal laser is good for making fast precise cuts in sheet metal. The waterjet can cut steel up to 1" thick but it takes a long time to cut thick materials. The finger brake allows you to make bends in sheet metal.  The shear is good for cutting straight lines in thin sheet metal or making smaller pieces.
 
   
 
   
These are a few good steps to having a successful weld.

Here are a few good steps to being successful in the Machine Shop.   
* Make sure the materials have no coatings. Welding of some coatings like galvanized metal can produce toxic fumes.  
+
* Make sure your workpiece is held securely before making cuts.  
* Materials should be properly prepped and clean for best results.  
+
* Metal can be hot and sharp so always be careful when picking up material pieces.  
* Make sure the process you are using is correct for your material type.  
+
* Make sure you you have been properly trained before attempting to use a machine.  
* Double check the weld settings and use a piece of scrap to practice before welding on your project.
+
* Keep hands away from moving parts on machines.
* Only weld steel and aluminum. Do not attempt to weld unknown materials.  
+
* Always ask if you have questions on how to do something.

+
* Never try to operate machinery when you are tired.  
* Never try to weld any type of tank that has ever held flammable liquids. This is very dangerous and can explode!
+
* Never work in the shop with loose clothing or items that could get pulled into a machine.
* Always check your welding hood settings prior to welding. (start with a darker setting and work your way down.
 
* Welding takes lots of practice so don't be afraid to ask for help.

<!-->
Stereolithography, SLA, is a part of the manufacturing technology of vat polymerization. This means a light source (laser) is used to cure liquid resin into a hard plastic.
 
The Form 2 is the only 3D printer that the Prototype Lab has that is an SLA printer. It utilizes the Upside Down or Inverted orientation.
 
The resin tank has a clear bottom with a surface the resin will not stick to. This allows the resin to cure against the bottom of the tank.
 
The build platform is lowered into the resin until it is hovering above the bottom surface of the tank, as far away as the height of the layer to be constructed.
 
The laser is directed through the bottom of the tank and cures a layer of resin onto the build platform. Then, the resin tank slides over and the build platform raises. The wiper will then sweep across the tank to circulate the resin.
 
The build platform will lower again, and the process will be repeated until the print is completed.
 
Due to friction caused by de-laminating every layer, every part should be canted in its orientation. This means the part should be angled to reduce the cross sectional area needing to be shifted to de-laminate each layer. This de-lamination also causes the Form 2 to be the Prototype Lab's slowest 3D printer.
 
Once a part is finished on the Form 2, it must be removed off of the build plate. Try to avoid scraping the build plate when removing parts. Any excess resin must be washed off using the Form Wash, the part must be air dried so that any isopropyl alcohol from the Wash has evaporated, the part should be cured in the Form Cure, and supports should be clipped off. Any remaining support marks can be sanded off if so desired.
 
Extra information on SLA Printing can be found [https://formlabs.com/blog/ultimate-guide-to-stereolithography-sla-3d-printing/ here].
 
 
 
==== <span id="FDM Printing Anchor">FDM Printing</span> ====
 
Fused Deposition Modeling (FDM) printers use a thermoplastic filament, which is heated to its melting point, then extruded to create layers which then build an object. There are many different types of FDM printers. Some use a modeling material and a support material, some just use a modeling material which when creating support will use a different style of layering that allows the filament to break off easily, some are able to use multiple filaments at once allowing for multicolored objects to be created. [[File:Filament_Spool.jpg|250px|thumb|right|Example of a filament spool for a FDM printer.]]
 
 
 
Both Stratasys printers (Dimension and F370) use soluble support filament (the support filament dissolves in a heated sodium hydroxide bath), the Prusa printers use only a model material, and the Markforge printer only uses model material as well (however it will layer another filament for extra support).
 
 
 
The filament for these printers comes in spools (basically thin plastic ropes that are wound up). The filament is fed through an extruder head, heated to the desired temperature, then extruded (similar to what happens with a hot glue gun).
 
 
 
FDM printers can work with various materials, in the Prototype Lab we mainly stick to ABS which is used by the Stratasys machines and PLA which is used by the Prusas. The Markforge uses a material called Onyx (nylon and plastic mix) and will layer in another filament such as Carbon Fiber, Kevlar, etc.
 
 
 
==General Bead Blasting Knowledge==
 
Bead blasting is the process of using compressed air to propel small glass beads for ablating and cleaning a material surface.  Different types of blast media are used in industry including Soda, Walnut shells, Sand and many more material types.
 
<br>These are a few good steps to having a Success with glass beading. 
 
* Make sure the material is free from heavy grease and dirt.
 
* The material needs to physically fit into the blast cabinet. 
 
Here are a couple things to keep in mind:
 
* Never point the nozzle at the gloves or window.
 
* Make sure the power switch is turned on before use.
 
* Always wait 5 minutes after use before opening the cabinet door.
 
* Never try to bead blast anything flammable. Blasting can sometimes create sparks.
 
*Never activate the foot pedal with the cabinet door open.

3 commandments

Safety First

Safety First is the rule we hold highest of the three. This rule applies to both the safety of you as well as others

Keeping yourself safe in the Machine Shop is very important, as there are possibilities for accidents if you don't follow the safety guidelines. Safety starts with you so don't depend on others to keep you safe. There is a first aid kit located on the south wall near the Wood Shop door.
The following rules must be followed at all times.


. Safety glasses must be worn when crossing into the shop area marked on the floor.

·        No horseplay in the shop.

·        Don’t do anything distracting to yourself or others while operating machinery.

·        Do not wear any loose clothing, jewelry, or lanyards.

·        No hats or open toed shoes.

·        Hair will not extend below the collar.

·        Do not wear gloves while operating powered machinery.

·        Food or drink is allowed when not operating machinery and it is kept a safe distance away from the machines.

·        Do not attempt to operate machinery in the shop that you have not been certified on by GFU engineering personnel.

·        Do not argue with volunteers or shop staff. Contact Justin Johnson if you have issues that need to be resolved.

·        Do not operate machinery without a shop supervisor or trained volunteer in the shop with you. Never operate equipment alone in the shop.

·        Reset the space. Make the area you are working in ready for the next person using the dust broom and vacuum cleaner.

·        The first aid kit is located in the machine shop, next to the Wood Shop doors.

·        If you see a safety violation inform the person immediately and encourage them to comply with the policies

·        Don’t do anything that would require an additional rule to be added to this list.

Reset the Space

The Machine Shop has a specific organization to it. Put whatever you use back where it belongs. There is a place for everything and everything has a place. This rule applies to everything in the space. If you use a tool, put it back. If you use a pen, put it back. Throw away your trash and recycling.

Now, we understand that sometimes you need to leave projects out. Maybe you are in the middle of a large project and you need something left overnight. In cases like this, it is okay, but you NEED to make prior arrangements with Nick or Justin.

Please put back the Machinery the way you found it. Clean up chips and any messes you make. NEVER use shop air to clean off the machines.

Always put any unused materials back on the storage shelf, and put small pieces in the scrap box.

Always leave the space better than you found it.

Be Professional

This commandment has two sides to it. It covers the idea of acting like professional (which Webster’s defines as “exhibiting a courteous, conscientious, and generally businesslike manner in the workplace”). The term also describes the standards of education and training that prepare members of the profession with the particular knowledge and skills necessary to perform their specific role within that profession. Hopefully, you are learning both of these as part of your education at George Fox University. In the Machine Shop we expect you to develop as a courteous, conscientious, and skilled craftsman, understanding the tools and equipment in the Maker Hub and how to use them effectively.

Being a professional has some obvious ramifications in terms of behavior. First, be Christlike. Think of others as better than yourself. Share. If you have been machining a for a prolonged time and someone else is waiting for the machine, let them use the machine for a while. This is being a professional.

If you are learning to how to use a machine, and you can't get something to work the way you want - ASK SOMEONE! Learn! Become a professional. Learn the craft. This is an educational space. You might think it will be quick and you can just get it done “your” way and not learn how to do it correctly. Be a professional and learn the proper way, and then be available to teach others.

One very important, and likely difficult part of being a professional is to correct others when they are not being professional. It is your responsibility to speak up when you see somebody doing something inappropriate. If you see somebody doing something unsafe, not resetting the space, or being unprofessional, the professional thing to do is to remind them of the three commandments and ask them politely to correct their behavior. This is OUR space, not any individual's. As a group, we expect everyone in the space to keep the space safe, clean, and operable for everyone. 

If someone acts unprofessionally in the Machine Shop, you are welcome to bring the issue to Justin or Nick's attention.

General Machine Shop Knowledge

Machining is the process of removing material so it is subtractive manufacturing. We have a variety of machines in the shop.

The 3 main processes include milling, turning, and drilling.

Each machine has its own special purpose and benefits. The drill press will produce holes quickly but normally has less precision than using a milling machine. The lathe is normally used for making round parts and drilling. The metal laser is good for making fast precise cuts in sheet metal. The waterjet can cut steel up to 1" thick but it takes a long time to cut thick materials. The finger brake allows you to make bends in sheet metal. The shear is good for cutting straight lines in thin sheet metal or making smaller pieces.

Here are a few good steps to being successful in the Machine Shop.

  • Make sure your workpiece is held securely before making cuts.
  • Metal can be hot and sharp so always be careful when picking up material pieces.
  • Make sure you you have been properly trained before attempting to use a machine.
  • Keep hands away from moving parts on machines.
  • Always ask if you have questions on how to do something.

Here are a couple things to keep in mind:

  • Material can be very hot after machining.
  • Machining can produce very sharp edges.
  • Never try to operate machinery when you are tired.
  • Never work in the shop with loose clothing or items that could get pulled into a machine.
