Collets & Collet Holders

This article gives a basic overview of the function and uses of collets, how to install them in collet holders, and finally their installation in the Haas CNC mill.
=== Overview ===
==== Collets ====
* A collet is a subtype of chuck that forms a collar around an object to be held and exerts a strong clamping force on the object when it is tightened.
* Reliable traits of collets include:
** Fast chucking
** Self centering
** Strong clamping
** Resistance against being jarred loose
** Precise centering
==== Collet Blocks ====
* Collet blocks allow collets to be used in conjunction with machines, specifically lathes or in the vises used with mills. They are a larger hexagonal or square piece of metal, in which the collet is able to slide through and be fastened at the other end.
	
	
== Types ==
=== R8 ===
* R8 collets usually fit into the machine taper itself (i.e. there is no separate chuck). R8 was developed to allow rapid tool changes. R8 collets have a keyway to prevent rotation when fitting or removing. R8 collets are internally threaded.
=== 5C ===
* 5C collets were developed primarily for work holding. 5C collets have an external thread at the rear for drawing the collet closed, and so work pieces may pass right through the collet and chuck.

Crop Strength Data Acquisition Device

A long standing problem for corn, wheat, barley and canola plants is lodging. Severe wind and rain causes bending of crop stems, making them difficult to harvest and therefore limiting yield. Predicting plant strength allows agronomists and industry partners to breed more resilient seeds for providing food, fuel and fiber to the world’s growing population.
=Problem Definition=
==Background==
As of Fall 2018, Dr. Robertson's team has three crop strength measurement devices. Each device records similar data, allowing one control unit to be used for each device topology. Industry partners are currently using the devices to characterize their crops. In return, they provide valuable data back to the University for further research.
===Existing Devices===

==Tool Speeds==
There is a chart outside of the Machine Shop Office that shows tooling and material speeds. Pay close attention to this whenever working with the Lathe. If you are unsure what material the tool is made out of be sure to ask, for the most part, if the tool is shiny it is made from High Speed Steel, and if the tool has a dull and greyish finish, it is made from or plated with Carbide.

Cutter Types (Mill)

Milling cutters are cutting tools typically used in milling machines to perform milling operations and occasionally in other machine tools. They remove material by their movement within the machine or directly from the cutter's shape.
==Milling Machine Tooling Overview==
 Various types of mill cutters:

== End Mills: ==
An endmill is a type of milling cutter, a cutting tool used in industrial milling applications. It is distinguished from the drill bit in its application, geometry, and manufacture. While a drill bit can only cut in the axial direction, a milling bit can generally cut in all directions, though some cannot cut axially. End mills are used in milling applications such as profile milling, tracer milling, face milling, and plunging.

High Speed Steel (HSS) tooling is Shiny in color, and relatively light in weight.
Carbide tooling is dull in color and relatively heavy compared to high speed steel. HSS is used for general purpose milling of both ferrous and non-ferrous materials. Carbide provides the user with the ability to run faster with less tool wear

==Centercutting and Non-Centercutting Endmills==
Milling tools are either center cutting or non-center cutting. Center cutting mills can plunge straight down into material, while non-center cutting tools cannot. Notice that the cutting edges of the center cutting end mill continues to the center of the tool. The center of the other has a small hole at the center. Non-center cutting end mills require a pilot hole, ramping or helical motion to plunge into material. the way you can tell the difference is the teeth of some cutters do not go all the way to the center of the end face.

Diameter Pitch

== Thread Pitch Diameter Display ==
A display with 2 studs of the same thread pattern and pitch diameter but with a varying minimum and maximum diameter of the thread.
== Purpose of Project ==
Two threads with different diameters but having the same pitch diameter might visually appear to be of different sizes. However, both are essentially the same and will fit in the same tapped hole (provided the hole is tapped according to the respective size). This can cause confusion as two threads with different pitch diameters but the same thread diameter will appear to be of the same size but will not fit in the same tapped hole. Therefore, when working with threads it is important to fully understand this concept. We aim to achieve this visually and logically in this page.
== Thread Diameter vs Pitch Diameter ==
===Thread Diameter===
There are two different thread diameters. The outside and inside thread diameters.
Major Diameter:The largest diameter of the thread of the screw or nut. When working with thread on screws the common term used is "outside diameter" and on threads of a nut the common term is "full diameter".
Minor Diameter:The smallest diameter of the thread of the screw or nut. When working with thread on screws the common term used is "core diameter" and on threads of a nut the common term is "inside diameter".
===Pitch===
The distance from a point on a screw thread to a corresponding point on the next thread measured parallel to the axis. In inches for example, the pitch is calculated by 1 divided by the number of threads per inch.
==How to Calculate Pitch==
 Procedure for measuring the pitch of a thread using the "Three Wire Method":

Dilution Tunnel

The dilution tunnel in the Small Engine Research Facility is used to dilute exhaust flow for particulate emissions data. By knowing the dilution ratio of the tunnel, we can calculate actual emissions based on the diluted emissions going through the tunnel. This tutorial explains how to set up and run the dilution tunnel.
==Dilution Tunnel Setup and Operation==
Image	Step
 	
Connect the dilution tunnel inlet line to an exhaust bung. The exhaust bung needs to be a ½ inch NPT male connection welded into the exhaust pipe at least 18 inches before the end of the exhaust pipe.
 	
Connect the TEOM sensor unit to the TEOM control unit. This is done by connecting both the data cable and small black tube to the fittings on the side of the sensor unit.
 	
Connect the vacuum pump to the TEOM control unit. This is done by connecting the green tubing to the fitting on the vacuum pump and the fitting on the TEOM control unit. Then turn on the vacuum pump.
 	
Turn on the TEOM control unit by flipping the front switch. The red check status light will turn on, indicating a temperature problem. This is not a system problem, it just means you will have to wait for the TEOM to warm up and initialize (about an hour).
 	
Turn on the HP VXI data acquisition unit and the computer next to it.
 	
Connect the dilutant supply to the lower fitting on the motive pressure valve. Open the valve just enough to let the air start to flow through the tunnel.
 	
Turn on the temperature controller and set temperature to 820 F. This will correspond to a suction temperature of 700 F. The temperature sensor consistently reads high due to being too close to the wall of the line heater.
 	
Turn on the Horiba Gas Analyzer. If necessary, connect the cable to the analog out port on the back of the unit.
 	
Connect the gas analyzer tubing to the dilution tunnel sampling chamber.
 	
Connect the TEOM inlet to the dilution tunnel sampling chamber.
 	
Start Labview and load Dilution_tunnel.VI
 	
Press MEAS on the Horiba emissions analyzer to start gas measurements.
 	
Adjust the valve on the air connection until Labview reads that the Motive Pressure is 35 psia. Then connect the Horiba inlet to the exhaust probe and put the exhaust probe into the raw exhaust stream for a few minutes while the engine is running. Record your CO2 reading.
 	
Press Stop Logging in Labview, then connect the Horiba inlet to the dilution tunnel line. Resume logging for a few minutes at the same engine point as before. Record your new CO2 reading.
 	
You are now ready to start engine testing. Your Dilution Ratio can be calculated using the two previously recorded CO2 readings. This ratio will remain constant throughout testing and will be used to convert from diluted measurements to what your engine is actually outputting.

Drilling and Tapping

==Description==
Tapping is the process of creating threads on the inner surface of a drilled hole. A variety of taps are available in the shop to match almost any screw type available, including metric and standard measurements. 
Information required to select the drill bit includes thread count, diameter, thread pitch, and coarse/fine threads.
==Good Practices==
===Using Tap Guides===
The tap guides, located in the same drawer as the taps, are crucial to creating a straight and usable tap. When tapping on a machine such as the Mill or Lathe, the tap is automatically centered and straight. Be wary of tap alignment when doing it manually, as the human eye isn't as accurate as a perfectly 90 degree tap guide.
===Using Oil===
Oil is a necessity while drilling and tapping. It prevents overheating, helps clean out the chips created by the bits, assists the cutting action, and prevents the bits from squealing. 
===Center Drills===
Creating a drilled and tapped hole first requires using a center drill. This gives the larger bits a center to align to, since most drill bits aren't perfectly centered when mounted in a drill chuck. This ensures the larger bits will drill in exactly the right place and won't walk across the part.
===Pecking===
While either drilling or tapping, pecking helps ensure the bits won't overheat or break. Pecking is the process of drilling into the part a way, then backing out to remove the chips and allow the part to cool. Common practice is to rotate the handle being used about a full turn, then back a half turn. Every time the bit/tap is pulled out, as many chips as possible should be removed and oil should be added to the surface and the bit/tap.

==Alternative Tapping Methods==
There are alternative ways to tapping other than by hand. It's possible to tap with the aid of the mill, lathe, and CNC. All the steps before tapping the hole are repeated before these procedures:

First fire test

====7/14/13 Fire====
To understand what temperatures a stainless steel casing would see during a fire, a peace of 2.5" pipe was buried and a small fire built on top. Eight thermocouples were placed to measure the case and internal air temperature at different depths. This information will be useful in preventing the probe's internal components from heating past their operating ranges. 
The data shows the the internal surface temperatures are higher then their outside counter parts. If the ground is treated as a heat sink that is the expected result. Also the lower into the ground, the lower the temperature, which is also expected since the heat source is above the ground.
Flowbench

The Flowbench is was designed and built at the University of Idaho to measure backpressure caused by mufflers, but can be used to find the pressure through any tube.
==Using the Flowbench==
===Plug-In Locations===
Because the flowbench uses six motors, the plug configuration is different than a normal outlet. Suitable outlets can be found on the pillars in the senior design suite.
===Main Power===
The main power for the flowbench is controlled by the uppermost black switch. This provides or cuts power to the other six on/off switches.
===On/Off Switches===
There is an on/off switch for each of the six individual motors, and motor one can also be controlled by the brass variable control knob on the side of the bench.
===Fuses===
The fuse boxes are located directly beside the on/off switches. There is a twenty amp fuse for each motor.
===Wire Color===
Wire Color is labeled on the fuse boxes: red corresponds to the two front motors, blue corresponds to the middle motors, and green corresponds to the two rear motors. All motors are wired in parallel, and each motor runs to power, ground and neutral.
===Air Inlet===
The air inlet is labeled and located on top of the flowbench. The plastic and rubber spacers can be used to accommodate different muffler/tube sizes. The inlet must be sealed for the flowbench to be useful.
===Mass Flow Sensor===
The Toyota Supra mass flow sensor requires a 12 volt power supply and a multi-meter to read the output. The output voltages must be recorded and compared to the calibration data. The easiest way to convert the output voltages to mass flow rates is to use Matlab to perform line regression. To do this enter the voltages and flow rates from calibration and find the equation of the line that is created, then apply that line to the new voltages. A quadratic equation should provide adequate results over the given voltage range.
===Pressure Sensor===
The pressure sensor is battery powered and calibrated to read zero when nothing is blocking the air inlet. The motors can be turned on and pressure drop will still read zero unless tubing is in the inlet. The pressure sensor has multiple built-in options: units, calibration, etc. The pressure drop across the muffler or tubing being tested will be shown on the pressure sensor when the motors are turned on.
===Troubleshooting===
If the flow bench is not working, check these first:
# Check fuses
# Make sure switches have not been overtightened and broken
# Make sure the wires in the plug have not come loose

General Dyno Instructions

If you plan on working in the SmERF, this page has the basic checklists for starting up an engine before testing and shutting down the SmERF when you are done.
thumb|left|General flow of data when testing an engine.
==Engine Start-Up Checklist==
# Check that engine is bolted securely to the dynamometer drive shaft and that the engine cart is secured to the dyno frame. For high vibration engines, zip tie or tape the hooks that secure the cart so they don’t rattle loose.
# Check that all coolant and fuel lines are fully connected and routed to avoid heat and rubbing.
# Turn on the SuperFlow control box and 12V power supply
# Check that the dyno coolant pump is on and that the tank is at least half full.
# Turn on fuel system, check that the tank is full and the fuel pressure is correct.
# Turn on the engine exhaust fan, cooling tower fan, and engine fan. The exhaust fan should be within less than six inches of the tail pipe but not inside the orange tubing.
# Check that the SuperFlow handheld is on, that there are no errors, the engine speed is set at least 1000 RPM above your engines idle speed, and that throttle is set to zero.
# If you are using the starter motor on the dyno check that the green light in the lower left of the starter control box labeled ‘Marcia/on’ is lit, if not press this button. The ‘Marcia/On’ button should now be lit.
# Press and hold the green button on the far right to start the engine. The starter uses a compressed air clutch to engage the dyno, check that the air valve on the wall is on and gauge reads about 15 psi.
==SmERF Shutdown==
# Turn off engine and engine electrical circuits.
# Turn off fuel systems.
# Turn fans off. Engine fan can be left on to speed engine cooldown.
# Turn dyno and cooling tower pumps off.
# Turn off 12V power supply.
