• What does folding paper have to do with math?
In this video, you will see an example of a linkage that has too much tolerance and is wearing out. You will need to use decimals to calculate minimum and maximum tolerances to find a tolerance that allows the part to work, yet not wear out as quickly.

• What do robots have to do with math? (KI)
In this video, you will look at needing to change dimensions to determine the proper robotic arm to order for a new welding enclosure. A blueprint is provided that you will measure several dimensions which then needs to be turned into a real-world dimension using the blueprint scale. The dimensions then need to be converted from inches to millimeters to determine the type of robotic arm to order.

• What do ramps have to do with math?
In this video, you will calculate the length of a conveyor ramp that needs to go up and over existing obstacles. You will need to use the Pythagorean Theorem to determine the length of chain and trigonometry to calculate the angle of the ramp.

• What do cookies have to do with math?
In this video, you will see how conveyors can be used in small spaces. You will be able to use knowledge of circumference of circles to find the length of chain needed to create a Spirex conveyor.

• What do holes in paper have to do with math? (1)
In this video, you will need to determine how many dies can be created per hour at different rates of speed. Once you know how many more dies, you will need to calculate how those numbers will affect the cost of production.

• What do robots have to do with math? (Georgia-Pacific)
In this video, you will learn about laser guided vehicles and how to program them to work in your company. You will need to calculate distances and angles.

• What does a tank reducer have to do with math?
In this video, a part needs to be welded onto an exterior part of a tank reducer. Exactly where the part is to be attached needs to be determined first, based on a blueprint. In this activity, students need to determine the correct length from the top of the tank to place the object.

• What does steel rectangular tubing have to do with math?
In this video, you will need to determine the total amount of tubing (assume the top of the riser will be added later) needed to produce a riser that will be used in a robotic welding enclosure at KI in Green Bay. You will be challenged to understand a two-dimensional figure (blueprint) that represents a three-dimensional object. You will also look at the loss of material from cutting.

• What does welding have to do with math?
In the Tool and Die Department, frequently soldering is used to manufacture parts and fixtures. The application of solder to a joint requires a specific skill set. It is important to not use too little solder, since the weld might give way. It is also important not to use too much solder, which is wasteful. In this video, students will determine the amount of weld material used in a series of "filet welds".

• What does steel scrap have to do with math?
In this video, students will learn how much steel it takes to manufacture 25 consumer zero-turn lawn mowers.

• What does a chair have to do with math?
Chair backs and seats are manufactured using a mix of various materials. In this task, students will determine amounts of materials necessary to produce an order of chairs for a classroom.

• How to use math when applied to cutting metals
Parts of a specified length must be cut from a length of milled metal. In this task, students will determine the number of parts that may be cut.

• What does a SINKING ship have to do with math?
Ship stability is an important area of naval architecture and design. How a ship behaves at sea in a variety of conditions is critical to the safety of crew and cargo. How can we ensure that our ship will float? In this video, you will use a mathematical model for a ship’s center of gravity to determine the stability of the vessel.

• What does dog food have to do with math?
Conveyor systems move products and materials from one area to another. The correct speed of the conveyor is critical to efficiently move product. Too slow and customer orders will not be filled. Too fast and the product may cause a big mess! This video asks students to calculate the correct speed of a Nercon conveyor system used to move dog food.

• What does color have to do with math?
Companies are always trying to find ways to save money while still maintaining the quality of their products. Looking for different sources for raw materials and different types of raw materials are methods procurement staff may use to find a cost savings. Careful calculations and problem solving are necessary when making these decisions. In this video we will investigate a possible new colorant supplier for chair backs and seats at KI.

• What do coffee filters have to do with math?
Manufacturers want to make sure they can make quality products while still being cost efficient. Sometimes there is an opportunity to upgrade a machine, which costs money but still may be more cost effective in the long run. How do companies figure out how much an upgrade will save them? When manufacturers talk about how much product they create per year, how much does that really mean?

• What do canisters have to do with math?
Manufacturers need to make sure that orders get placed but that they don’t make too much extra so that they have to store it in their warehouse. As they make a changeover from one product to another, they need to determine how much they still need to make. Companies also want to make sure that their manufacturing machines are running smoothly, so they need to keep track of how much scrap product is made.

• How does raising a ruckus involve math?
Customer safety is a high priority for manufacturers. When designing a product, many prototypes are created and research is conducted to determine if the product is safe for customers. In the case of furniture, stability is a critical area to test. This video shows how mathematics and physics help to create a stable chair, and ultimately, keep customers safe.

• What do waves have to do with math?
Waves in a body of water are not constant. They often have different lengths, heights and directions. In order to design ships to survive these varied wave conditions, naval architects analyze wave data from bodies of water where the ship will be sailing. In this video, you will be given Lake Michigan wave data to analyze and make inferences about. We are confident you will be able to sail through the mathematics in this video without getting sea sick!

• What does a bracket have to do with math?
When a customer places an order for a product, the customer expects the product that is delivered to be exactly what they ordered. Due to manufacturing variability there will be unplanned differences in the product. Some differences are so slight that they will not impact the performance of the product. Others will be large enough that the product will no longer work for the customer. This video explores how a manufacturer uses math to check for those differences.

• What does a conveyor have to do with math?
In this video, we see that a conveyor system does not always move product horizontally or vertically. It can also move product in more than one direction at a time, including an elevation change. Building this type of conveyor incline requires more knowledge of mathematics. Let’s see how 3D geometry helps us accomplish this.

• What does injection molding have to do with math?
Companies are always trying to find ways to save money while still maintaining the quality of their products. Looking at data regarding production downtime and how to minimize it can provide a cost savings. Gathering downtime data, interpreting that data and problem solving are necessary when making these decisions. In this video we will investigate data from a new injection molding process that uses different colors for chair backs and seats at KI.
