[Audio] Welcome to the Dynamic Torque 101 Training class. This class is intended primarily for those employees who use a Torque instrument. Although, it can be also valuable tool for anyone who wishes to expand their knowledge on the subject..
[Audio] Here's some of the subjects we'll be covering today: We'll start off with a basic torque definition Then we'll discuss how Torque is used in Dynamic We'll talk about torque monitoring methods Which will lead us into the Daily Torque Audits. Finally, calibration labels and certificates..
[Audio] What is torque? Torque is the turning or twisting of force applied in tightening a bolt or screw. Torque= Force X Lever Arm Unit of Torque= (Unit Of Force) X (Unit of Distance) Unit of measurement : N m and FT.LB. & In.LB..
[Audio] Here at Dynamic, we have a variety of tools to help us torque. Torque Wrenches DC Nut runners – Wired and Wireless. Pulse Tools, Air Nut runners, Impact Wrenches.
[Audio] Let's start with torque wrenches.. Torque Wrenches.
[Audio] We have 4 types of Torque Wrenches. The first one we'll cover are Dial Torque Wrenches. Things to know when using them: Accuracy: Typically, ±2% to ±3% of full scale. Has a second needle that stays at the peak torque applied, useful for reviewing after use. Zero the pointer before each use to ensure accuracy You must watch the dial while using it as to not pass the target torque..
[Audio] Digital Torque Wrench Extremely accurate (±1%–2%). Shows live torque in multiple units (Nm, ft-lb, in-lb). It beeps, lights up, or vibrates when you've reached your set torque..
[Audio] Click Torque Wrench 3% - 5% accuracy. Allows us to set a specific torque value. When you reach that preset torque while tightening a fastener, it makes a distinct "click" sound - letting you know to stop turning. Only tells you when you've hit the target—not how much torque you applied. DO NOT continue to apply force when you hear the click..
[Audio] Click Torque Wrench & T-Handle Torque Wrench (3%-6% accuracy) Allows us to preset torque. Used for low-torque applications. "Breaks" or "slips" at the set torque value, preventing overtightening..
[Audio] These are all the torque wrenches we use in Dynamic. Now depending where you end up working, you may not use some of these..
[Audio] Moving on to DC Nut runners.. DC Nut Runner.
[Audio] We have wireless & wired nut runners. Accuracy and function of buttons. If trigger is released early lights will light up on inline tools, and wireless tools will vibrate. Make sure tool is parallel to the bolt..
[Audio] VF Icon (factory icon) – VF Connection When GREEN VF is connected. When RED, VF signal is lost or disconnected. Contact Metrology if that happens. WiFi Icon – Tool Connection. When tool is connected to the controller, it lights up GREEN. When tool is disconnected, or tool goes to sleep mode, the light turns RED. To test if tool is asleep, just press the trigger and it should turn green..
[Audio] Socket Tray – The socket tray is used when different sockets are required for various Bolts. Each socket holder has a light above it that illuminates when the socket is removed or if it's needed for the next set of bolts. If the lighting system isn't functioning properly, please contact the Metrology department for assistance. Torque Arm – The torque arm is an ergonomic tool designed to help hold the tool comfortably during long usage periods. If any part of the torque arm is loose or malfunctioning, contact Metrology immediately, as this could present a safety hazard..
03. Pulse Tool. Impact Wrench. Air Nut Runner. Air Ratchet.
Pulse Tool. Pulse Tool: Operates using hydraulic pulses to deliver torque with reduced reaction force. It provides moderate torque accuracy and is ideal for medium-torque applications with fast cycle times..
Impact Wrench. Impact Wrench: Uses hammering action to deliver high torque. It has the least torque accuracy and high noise/vibration levels, making it more suitable for non-critical fastening where precision is not essential..
Air Nut Runner. Air Nut runner: A direct drive tool providing highest torque precision with continuous drive. It’s best suited for critical joints where tight tolerances and traceability are required..
Air Ratchet. Air Ratchet:. A green and black tool AI-generated content may be incorrect..
Pulse Tool. Impact Wrench. Air Nut Runner. Air Ratchet.
[Audio] Next, we'll talk about Recheck Torques. A method we use to ensure our fasteners maintain the specific torque value. Recheck torque is the practice of verifying that fasteners maintain the specified torque value after initial tightening and use.
[Audio] Step-by-Step Instructions: 1. Preparation: Ensure the digital torque wrench is calibrated. Set it to peak mode. Confirm torque specification. Do not disturb the fastener before checking. 2. Positioning: Place the correct socket on the fastener. Keep the wrench square to avoid side loading. 3. Torque Application: Apply slow, steady torque in the tightening direction. Stop immediately once the fastener moves. Record the peak value shown..
[Audio] Torque in Dynamic. What's the big deal? Why is it important?.
[Audio] Safety - Our products are used in major branded vehicles worldwide. Mistakes in torque can cause leaks, loss of propulsion, electronic failures, and more. Quality -Dynamic prides itself having the highest quality standards for all the products we ship. Cost – Mistakes in torque can lead to test stand failures. Our root cause operators must open the unit to investigate the failure. Which leads production to have to build another unit to meet the order quantity. This is called the cost of poor quality. Warranty – Mistakes that make it past our test stands and out in the field can lead to product warranties. If a transmission leaks or fails in someone's vehicle, that transmission will go back to a dealer who will ship to us. If the problem is severe across many transmissions, it could lead to a product recall. We'll determine how many units were affected and bring those units back. Recalls could ultimately cost Dynamic up to millions of dollars..
[Audio] At Dynamic, we identify two key characteristics that are critical to our process. In the transmission division, its bolt torques. In the torque converter division, its weld seal..
[Audio] Key characteristics are defined with the following symbols. You will find these symbols on job instructions and support documents. The one concerning torque is the diamond with DMI in the center (top left). This indicates that a torque or a weld seal is being performed..
[Audio] Imagine parking your car at the top of a hill for a picnic. Only to have it roll down on its own and fall into a lake! Do us a favor and look for these Safety symbols on the job instructions..
[Audio] Here's an example of how we call out define a torque parameter on a torque tightening pattern. This first image is of a torque tightening pattern that's showing you the target and recheck torque. These documents can be seen hanging in your departments or on monitors. **** Split slide to add current VF photo ****.
[Audio] Here's an example of how we define a torque parameter on a job instruction..
[Audio] Here is an example of where you'd find the PRAM symbol on a job instruction. The instruction is for Final Case Prep and is having the operator install the park pawl actuator. This is a safety critical operation, and you must be careful when following these instructions..
[Audio] Our customers require us to monitor torque through the following methods. The first is Target Torque. This value is a customer requirement and comes from the blueprint. It's what our department uses as guidance to program your torque tools. The next is Recheck torque. This is the torque range that we allow the fastener to be after assembly. All fastened bolts will change torque after a run down. That is why this next one is so important. Daily Torque Audits. You're our first line of defense against bad torques leaving Dynamic. We rely on you to accurately record these audits, so we have we have real time data on how the tools are performing. Our second line of defense is our weekly teardown audits. These are performed by a Quality Technician who disassembles the transmission and verifies that all torques are within their recheck range. Lastly, we have calibrations. Calibrations are performed at a minimum of once per year. We compare your instrument to a master sample. If it passes, we apply a calibration label..
[Audio] This is an example of a twice daily torque sheet. It's the paper that you use to record recheck torques. On this sheet you'll find the fastener name and recheck torque range. In the right-hand corner you'll find the symbol identifying torque as a key characteristic. 5 days of recheck audits are expected, twice per day..
[Audio] On the Ford and JP lines, we use data software paired with a Bluetooth torque wrench. The wrench sends torque data to the software, which then saves it to an Excel sheet. Here's what the software looks like when in use..
[Audio] We ask that you do your morning torque audit around 7am. The afternoon check should be performed right after lunch. We want to know that your tools are performing correctly before you build a lot of transmissions. It's always easier to do the torque audit, then it is to go back and disassemble transmissions to fix a problem. Don't check the same bolts every time. Check 3 or 4 bolts in a pattern or sequence to ensure the torque tool is outputting properly. You're providing us valuable information on how our torque tools are performing. If you notice any out of tolerance readings, please notify your supervisor. You will not get in trouble..
[Audio] The data that you give us on the twice daily torque sheets is entered into a master database. Quality will analyze the data and the Metrology group will be contacted to investigate out of tolerances. Our first step will be to calibrate the tool. If the calibration is good, we'll look at variance in the part. Are the bolts dirty? Are the internal threads corroded? These factors can often lead to low torques. Next, we'll look at training. Is there a new operator? Do they need training? The Metrology Group is always willing to give demonstrations to ensure tools are used correctly. If we're unable to find the root cause through any of the previous routes, Metrology has the option to adjust torque parameters, as long as we can keep the recheck in range..
[Audio] These are our calibration labels. We typically calibrate all instruments on an annual basis. If a tool fails calibration, we may increase the calibration frequency in order to more closely monitor the tool output. If a tool passes calibration, we'll apply one of these calibration labels. We typically only see these labels once a year, so if it's peeling or missing let a supervisor know so we can replace it..
[Audio] If an instrument is too small to hold a calibration label, we may issue a calibration certificate. You may see these hanging in your area with the Job instructions. They can be linked to the instrument with the serial number or engraved Gage number..
[Audio] Pay attention to your job instructions. They contain those symbols which are key to the build process. Do your daily torque audits. We review the results. Having out of tolerance is not bad! We need that information to adjust the process. Check your calibration labels. It takes 5 minutes for us to replace a label. If an auditor finds a gage missing a label, it could lead to a potential finding. If you're not sure how to use an audit or assembly tool, have you supervisor request a demo. Any member of the Metrology team would be happy to show you the proper method..
[Audio] Thank you for attending this presentation. We've reached the end of the Dynamic Torque 101 Training. If you have any questions following this presentation, please reach out to myself or a member of the Metrology Team. Have a great day..
