Mastercam Milling Operations

The milling process in Mastercam uses the Contour toolpath. This is used to face edges and create filleted corners parallel to the tool(see the third image in the table).
Image	Step
 	
You can create a Contour toolpath by either following the process shown to the left, or by clicking on 'Toolpaths','Contour' in the uppermost toolbar.
 	
Mastercam will now ask you to select the edges to mill. You can do this a few ways, this image shows how to use the individual edge selection. If you do it this way, make sure the arrows(in the yellow circle) are facing in the correct direction for a continuous cut. Select the reverse button to switch the direction of a chain. Click on the green check mark when you're done.
 	
When the next window opens, click Contour, then click on 'Tool'. Next, click 'Select Library Tool', find your tool in the library, and double-click it. If you cannot find the tool you need, uncheck the 'Filter Active' box.
 	
Make sure the correct tool is selected in the window, then correct 'Tool #','Spindle direction','Feed rate', and 'Spindle speed'. Feed rates and spindle speeds can be found using the charts in the machine shop and are based on tool, tool size, and material. Spindle direction will depend on whether you want to climb-mill or conventional-mill. Also, make sure that 'Plunge rate' is lower than 'Feed rate'.
 	
If you plan on using the same tool for finishing and roughing set the two 'Stock to leave...' sections to zero. If you plan on using a different tool for finishing, set 'Stock to leave on walls' to about 20 thousandths for the roughing toolpath, then to zero for the finishing toolpath.
 	
Next, click on Depth Cuts, setting your max rough step(the most the machine will take off in one pass). For finishing, set a number and step size for finish cuts. Usually you'll want multiple small cuts for a nice finish. If you used a different tool for roughing and finishing, set '# Finish cuts' to zero for the roughing toolpath and set 'Max rough step' to zero for the finishing toolpath.
Note: The max rough step should never be greater than the diameter of the tool you're using.
 	
The Lead In/Out tab is used to reduce load on the tool and improve the cutting effectiveness at entry and exit. Checking the 'Lead In/Out' box at the top, selecting 'Tangent' under 'Entry' and 'Exit' and setting 'Sweep' to either 45 or 90 generally works well.
 	
In the Coolant window, set 'Flood' to 'On'. You are now done a milling toolpath. Click the check mark to finish the toolpath. If you are using a different endmill to finish, repeat the process following the changes given in steps 6 and 7.
Mastercam Pocketing Operations

To create a pocket in a part, you use the Pocketing toolpath. This is fairly similar to the Contour toolpath, but instead of following a line, the tool will cut out an area.
Image	Step
 	
You can create a Pocket toolpath by either following the process shown to the left, or by clicking on 'Toolpaths','Pocket' in the uppermost toolbar.
 	
Mastercam will now ask you to select the edges of the pocket. Click on the edges of the pocket in consecutive order so as to make a continuous loop. If the pocket needs to open into the edge of the part, you will need to create a few lines starting at the edge of the part and extending away from the prat. You will then need to set these lines as vertical or horizontal borders. Then you can click on them as part of your chain. Click on the green check mark when you're done.
 	
When the next window opens, click Pocket, then click on 'Tool'. Next, click 'Select Library Tool', find your tool in the library, and double-click it. If you cannot find the tool you need, uncheck the 'Filter Active' box.
 	
Make sure the correct tool is selected in the window, then correct 'Tool #','Spindle direction','Feed rate', and 'Spindle speed'. Feed rates and spindle speeds can be found using the charts in the machine shop and are based on tool, tool size, and material. Spindle direction will depend on whether you want to climb-mill or conventional-mill. Also, make sure that 'Plunge rate' is lower than 'Feed rate'.
 	
When Pocketing you'll want to set the machine to climb mill. If you plan on using the same tool for finishing and roughing set the two 'Stock to leave...' sections to zero. If you plan on using a different tool for finishing, set 'Stock to leave on walls' to about 20 thousandths for the roughing toolpath, then to zero for the finishing toolpath.
 	
Next, click on Roughing, picking either Parallel Spiral or Constant Overlap Spiral as your cutting method. Then click on the Finishing tab. Uncheck it if you are going to use a different tool to finish, or set it to either Parallel Spiral or Constant Overlap Spiral.
 	
Set your max rough step(the most the machine will take off in one pass). For finishing, set a number and step size for finish cuts. Usually you'll want multiple small cuts for a nice finish. If you used a different tool for finishing, set '# Finish cuts' to zero for the roughing toolpath and set 'Max rough step' to zero for the finishing toolpath.
Note: The max rough step should never be greater than the diameter of the tool you're using.
 	
Make sure that all of the dimensions in the Linking Parameters tab are set to 'Absolute'. Also, make sure that you input depth as a negative number.
 	
In the Coolant window, set 'Flood' to 'On'. You are now done a pocketing toolpath. Click the check mark to finish the toolpath. If you are using a different endmill to finish, repeat the process following the changes given in steps 5 through 7.
Mastercam Scalloping Operations

Scalloping is the process of using a ball endmill to create a chamfer along an edge
Image	Step
 	
You will need to create a box slightly large than the surface you want to scallop, to compensate for the round endmill. Create the first line along the top of the chamfer, making sure that you restrict it to being horizontal. When you've made the first line, click the Apply button (white plus inside the blue circle) to start the next line.
 	
Next, switch to a side view and create a line along the edge of the chamfer. Note the length and angle shown in the upper left corner. Go back to the isometric view to create a line starting at the end of the first line, making sure that the angle is the same as the previous line, and that the length is at least one tool diameter longer than the previous line.
 	
Create a line parallel to the one you just made, starting at the other end of the first line. Finish the boundary box by creating a line that connects the two diagonal lines.
 	
Create the Scalloping toolpath by either following the process on the left or clicking 'Toolpaths', 'Mill', 'Surface Finish', 'Scallop' in the uppermost toolbar.
 	
When it asks you to select the drive surface, click on the chamfer face.
 	
When the next window opens, click on the pointer under "Containment boundary", then select the lines you created in an order that creates a single, continuous loop. Click on the green check. There should now be a (1) under "Containment boundary". Click the green check.
 	
When the next window opens, select the desired ball endmill. A larger endmill will leave fewer ridges on the chamfer, while a small endmill will give finer cuts near the top of the chamfer. Click 'Coolant', then turn "Flood" on. Make sure "Spindle Direction" is set to 'CW'.
 	
Under the "Surface parameters" tab, set "Compensate to" to 'Inside'. This will prevent unwanted loss of material at the top of the chamfer. Click on the green check mark to finish the toolpath.
Mastercam Verification and G-Code

This tutorial will walk you through final machine selection, verification, and G-code generation
Image	Step
 	
Once your toolpaths are complete, save your part and open it on the computer in the machine shop. Once you have it open in the shop, expand the "Properties" tree and follow the file path shown on the left. Select "HASS MILL" from the machine list and then click 'Open'. You will need to regenerate all of your toolpaths.
 	
To verify that your code still does what you want it to do, click the leftmost circled button in the image shown to select all operations. Then click the center circled button to regenerate the selected toolpaths. Finally, click the rightmost circled button in the image shown to play an animation of your code being run on the machine.
 	
This screen will open after completing the previous step. Set your view speed to as low as possible, speeding it up as necessary while viewing the operations. If there are any major errors (drills staying down while changing position, endmills running above the stock, etc.) you need to go back and edit your toolpaths.
 	
When everything looks good, click the G1 button. Click the greeen check mark when the "Post Processing" window appears. A "Save As" window will open. Make sure you save the code as a .NC file and that you save it with a new name and/or location.
 	
Once your code has a file destination, the Mastercam Code Expert application will launch.
 	
Once Mastercam Code Expert has loaded, you should see a screen with a code on it similar to the one shown to the left. If you have any experience with G-code, you should look over the code and see if there are any lines that obviously don't belong. If everything looks good, you are ready to run your code on the HAAS Mill.

==MasterCAM Mill Facing==
Image	Step
 	
#Start the MasterCam
#open part
 	
# Right click in the toolpaths bar (left hand side)
# Select Mill toolpaths 
#Face
 	
Once facing operation has been selected, the 2D toolpaths pop-up will come up.
Toolpath type option needs to be selected first, and is shown in the figure to the left:
# Select facing 
# Select type of chain (can use the mouse to select the edges on the model that surround the face you wish to cut)
 	
Next, you must select the tool:
# Click the library tool button
# Select tool.
# Adjust Feed, Spindle, and Plunge rate. 
Website to help adjusting rates: 
(http://www.daycounter.com/Calculators/GCode/Feed-Rate-Calculator.phtml )
You don’t need to change the SFM, it’ll change by itself once you set the rate values.
 	
Next, select the tool holder.
Open library and the proper holder.
No need to change a lot of stuff here, the tool holder selected is not that important.
 	
Next, specify the Cut Parameters 
--> Depth cuts
# Set your max. rough step. (the depth of each cut)
(i.e. Alumunium between 0.025-0.050in, steel 0.010 -0.025 in)
# Number of Finish cuts.
(how many times should the machine do last finishing)
# Finish step
(how far the depth is for finishing)
 	
Next, adjust the Linking paramaters
Adjust the values that needed to be adjusted:
-Retract: is the value to which the tool rises before moving to a new position.
-Feed plane: is the height above your part at which the specified plunge rate and feed rate become active.
-top of stock: is the distance (in the z-direction) from the set origin to the top of the stock
-depth: is the total depth to be cut off
 	
Don’t need to change anything in the this page.
-make sure coolant is set to on
-can skip through the last pages and leave them with their default values
-click the green checkmark when done
 	
To check if everything is going according to the dimensions you just added, click machine at the top verfiy

Max Machinery Fuel System

The Max Machinery 710 Series Fuel Measurement System is used in the Small Engine Research Facility to keep track of fuel usage. It reads both total fuel usage and a fuel usage over a set time period.
==Setup==
Before starting your engine on the dynamometer, make sure there is sufficient fuel in the red tank next to the fuel cart to run your tests. If the fuel in the tank is not correct for your engine, clean and fill a tank from the fuel storage room and hook it up to the Max Machinery Fuel Measurement System, all of the lines are clearly labeled. Once everything is hooked up, turn on the power supply on the fuel cart and start your engine. Be sure to check periodically for any leaks on or around the fuel tank and fuel cart.
==Testing==
Once you are at the desired engine testing point, press the START button on the data box in the observation room and simultaneously start a stopwatch. Press the STOP button on the data box and stop the stopwatch when the “Total kg” screen reads about 0.1 or when the stopwatch reads 25-30 seconds. This is done to reduce error in timing the stopwatch and fuel system. Record the fuel mass and duration. You can also find the total amount of fuel used over a testing cycle from the “Kilograms of Fuel” screen.
==Troubleshooting==
Morse-Taper Drills

==When to Use a Morse-Taper Drills==
* Used when a hole larger than 1/2" is needed
* Can be used on the mill, lathe, and big drill press in the shop
==Guide to Using Morse-Taper Drills==
NOTE: Do not attempt to chuck Morse taper drills into a standard drill chuck. Their tapered shaft is not compatible with standard non tapered drill chucks.
===Location===
Morse taper drills, sleeves, and drift punches are located in the top two drawers on the left side of the large grey tool box (#3) across from Russ' office in the shop. 
===Assembly===
Step 	Illustration
If a drill chuck is inserted into machine, remove it by inserting a drift punch into slot and tap drift with a lead hammer. Hold drill chuck with other hand to prevent it from dropping. 	
Wipe the tapered part of the Morse drill bit's shaft to ensure a clean surface. 	
Next, insert bit into sleeve, mill, lathe, or drill press and rotate until flat tab on bit falls into slot. 	
If inserting into a sleeve, hold the assembly upside down and tap with medium force onto a hard surface once or twice to seat drill bit. 	
If inserting into drill press, mill, or lathe, tap end of bit with a lead hammer once or twice using medium force to seat bit. CAUTION! USE ONLY A LEAD HAMMER! Other hammers will damage or dull the bit.	
Follow the same procedure for using regular drills regarding safety, cutting speed, etc. 	
===Disassembly===
Step 	Illustration
To remove bit from drill press, mill or lathe, insert drift into slot and tap with a lead hammer until bit releases. Keep one hand on bit to keep it from falling.	
To remove from sleeve, either follow the last procedure, or you may tap drift by striking it on a hard surface while it is inserted into the slot on the sleeve. 	
To reinstall drill chuck, first retract jaws below the body so that they are not damaged by the lead hammer. 	
Next replace the drill chuck, rotating until tab lines up with slot. 	
Last, tap once or twice with lead hammer using medium force to seat drill chuck.

New CMM

===Description===
The Coordinate Measuring Machine (CMM) is located in the back-right corner upon entering the Metrology Lab. It is used to measure parts accurately for inspection and reverse engineering. 
===Principle Uses===
The CMM excels at precision measurement and geometries that would be otherwise difficult to measure:
*Center and diameter of large holes
*Center and radius of curvature 
*Flatness/Straightness
*Orthogonally/angles between planes
===Principles of operation===
The CMM uses high-precision encoders and air-bearings to allow tracking the position of a measurement head in 3D. Combined with a computer it can interpret the RAW XYZ coordinates to calculate distances and complex geometries. Our machine is manually moved by an operator, but more complex computer driven models exist and are used in many industries.

Next Gen FHSAE Engine

The purpose of this project is to design and manufacture a robust platform for testing and development on the next generation SAE car.
== Problem Definition ==
Design a robust platform for testing and optimization of the next generation Formula SAE vehicle utilizing a KTM 540 motorcycle engine and a small frame drivetrain.
===Background===
The mechanical engineering department's Formula Hybrid car has been doing well in recent years at competition and now would like to experiment with the idea of venturing into the larger displacement and more competitive Formula SAE competition. This competition has major U.S. schools sending cars with full aerodynamics, carbon fiber frames, and budgets greater than $300k. Currently we do not have the backing to directly compete with these cars and their budgets, but we have shown we can design some very innovative and high quality components. This has encouraged us to try our hand at repackaging a KTM 540 motor into a few different configurations and showing our results at the national competition in hopes of gaining new funding and just impressing the competition.
===Deliverables===
====Primary====
:•	Disassemble the KTM 540 engine and utilize Designworkz to trace complex geometry
:•	Make detailed measurements using calipers and micrometers 
:•	Construct a CAD model of the engine in Solidworks
:•	When drivetrain is procured, disassemble and obtain measurements for CAD modeling
:•	Determine optimal drivetrain configuration for maximum efficiency 
====Secondary====
:•	Construct car frame and body in Solidworks around the optimal configuration
:•	Utilize engineering analysis on engine, frame and drivetrain using computer models (MATLAB and ABAQUS) and hand calculations to guide design
:•	Manufacture/Procure materials and parts to create final product
===Specifications===
:•	KTM engine must be modeled as accurately as possible
:•	Drivetrain must be realistic for engine size/capability
:•	Frame design must be compact and lightweight
:•	Several drivetrain configurations must be designed and compared to determine the balance between reality and efficiency
:•	FSAE rules and regulations must be followed and factored into the design
==Project Learning==
:•	Gain experience with 3D modeling of real world parts

It can print at a speed of 40mm/s or lower is recommended due to a noise, it can go faster to 200mm/s but that is not recommended.
•The purpose of the bed lock is to easily reinstall the bed sheet on to the bed. When you are reinstalling the bed sheet, if the bed lock button is enabled, it will hold the bed so that the bed won't be pushed back when you slide the bed sheet on to the bed. Aside from this bed lock function, when the print is completed, the bed is automatically lowered to the bottom and the long screw that is on the bottom of the bed holds the bed which works the same as the bed lock function so you don't have to worry about pressing the bed lock button when the print is completed. You will be using the bed lock button when you have to reinstall the bed sheet after you cancel the print or in situations where the bed is not at the bottom of the printer.
