Routing manufacturing, sometimes referred to as production routings, is the route to be followed during each step of the manufacturing process when transforming components and raw materials into a finished product.
Routings show the production flow that needs to be achieved. This can be done in one or more facilities or sent to an external vendor for specialized tasks. A task is an action that is performed to make the product. For example, the steps could go in an order such as:
Routing details the steps needed to take and, in the order, they need to be completed to create your product.
Along with this, the routing highlights the materials and equipment/workstations that will be used to manufacture an item, all derived from a product’s bill of materials. For a simpler explanation:
Routing = lists of tasks needed for a manufacturing process used to make a product
The same routing can be used for multiple products if it has a similar process. Also, a product may go through one process more than once before moving on to the next stage. If this is the case, the number of cycles must be specified in routing manufacturing.
So, determining your routing in operations management will help you understand the path and sequence of operations needed to be completed on a product as it passes from one process to another.
But what’s the purpose?
The aim of routing manufacturing is to establish the optimum sequence of operations at the lowest cost and complete it in the quickest amount of time. Routing manufacturing does not mean that you can take any shortcuts. You still have to review your production quality control checklist to maintain the highest quality.
Routing is an important base for organizing your business as it defines the manufacturing method.
When figuring out your routings, consider:
The tasks that need to be carried out to manufacture an item
The work centers (where production activities are performed) in which these tasks are carried out
The sequence in which a product passes through the processes
Once you’ve completed this, you’ll have your routing document applied to each product you manufacture. This lists all production operations and processes, in chronological order, that take place to complete the final product.
Primarily, routing manufacturing will provide grounds for scheduling and measuring the capacity of production resources.
What is an example of routing in manufacturing?
To breakdown the definition of routing in manufacturing further, here’s what a typical manufacturing example looks like for a business that builds its own bicycles:
Frame welding — the first step in the routing process for a bicycle might be frame welding. This involves joining the various frame components together using welding equipment.
Frame painting — once the frame is welded, it might be sent to a paint booth for painting. The painting process might include several steps, such as sanding, priming, and applying multiple coats of paint.
Wheel assembly — the next step might be wheel assembly. This involves attaching the spokes to the rims, mounting the tires, and attaching the wheels to the frame.
Gear assembly — once the wheels are attached, gear assembly might be next. This involves installing the gears and derailleur onto the frame and attaching the chain.
Final assembly — the final step might be the final assembly. This involves attaching the bicycle’s handlebars, seat, pedals, and other finishing touches.
Quality control checks might be performed throughout the routing process at each step to ensure that the product meets the required standards.
For example, welds might be inspected for strength, the paint might be checked for evenness and durability, and gears might be tested for smoothness and accuracy. By carefully planning and optimizing the routing process, manufacturers can ensure the production process is efficient, effective, and high-quality.
What is process route modeling?
Process route modeling typically involves using flowcharts or diagrams to represent the process flow. A symbol or shape represents each step in the process, and the arrows between the symbols indicate the sequence of steps. The model may also include information on the inputs, outputs, and resources required for each step in the process.
Routing in production planning and control
Production routing means as soon as a manufacturing order is generated, you and your employees will know immediately what tasks need to be carried out at what work centers, significantly cutting down your manufacturing lead times.
This will vary depending on what type of manufacturing business you operate. For larger companies that use repetitive manufacturing, the products are standardized, so no managerial effort is really needed since the products go through one movement.
However, the quaint, proud, and scaling manufacturers will need to establish routes as their highly customized items whizzing all around the shop floor.
Routing a production order requires:
The information on the product being manufactured
Details of each relevant operation
The set-up time
The standard time is needed to finish the production
The routing procedure consists of six points:
1. Make and buy decision
You’ll need to decide which parts and components are to be made by yourself or bought in. You decide this by price comparison, availability of resources, if you have the appropriate tools, and whether the materials and machines are available.
2. Bill of materials
Your bill of materials determines the materials required for production. Using a BOM means procuring the relevant material and components before production starts.
3. Preparation of route sheet
This is where you’ll need to look at operations and pair them with a sequence to manufacture the product. This establishes the operations needed to process a product, listing them in their sequence on the route or operations sheet.
4. Lot size determination
This is where you determine the capacity that can be produced at one location. However, “If the product is to be produced to fulfill the consumer requirements, the question to determine the lot size does not arise.” This is mainly a concern for businesses that use a continuous or repetitive manufacturing workflow.
5. The scrap factor
You’ll need to estimate the amount of scrap produced during the manufacturing process. As we know, all the components produced at various workstations do not meet the required standards, and those that do not pass inspection will be neglected as scrap.
Scrap may be produced at one point during the manufacturing process or progressively. You’ll need to determine these points and take the appropriate action to deal with the buildup called a scrap factor. Normally this is decided from previous experience, and you’ll need to direct resources to remove scrap to avoid bogging down machines.
6. Provide necessary information and forms
As you probably know, manufacturing and business management can be dull and bureaucratic.
Unfortunately, your routing manufacturing is no different. You’ll need to have your manufacturing orders, job tickets, inspection tickets, move orders, tool tickets, and equipment tickets.
However, for businesses with around 2 to 15 employees, this might not be necessary. Although, it’s a good practice to have your floor-level management to this high standard of the organization to avoid bottlenecks and backlogs.
As you can see, preparing routing in production requires a mental sweat. But once you have taken the time to do this, you’ll be able to reap the benefits.
Cloud manufacturing software
Get real-time visibility of your entire workflow to make better business decisions. Find out why thousands of manufacturers use Katana to track their inventory and operations.
For a production routing example, let’s use a business that manufactures customized wooden glasses. They have their routing manufacturing planned out might look something like this in action:
Design — As per the customer’s specifications
Preparation of material and cutting — Getting everything ready
Shaping — Setting the shape of the glasses into the desired final shape
Varnishing (‘X’ number of cycles) — Varnishing the glasses, so they keep their shape. This has to be done several times
The final product — The final touches are made on the glasses
Packaging — The glasses are packaged and ready for delivery
Shipping — The glasses are shipped off to the customer
The production routing example shows that the final stages of manufacturing your products will be packaging and shipment. However, without planning the route beforehand, getting to this stage will be delayed by your items getting lost on the shop floor.
