Lean manufacturing concepts have been around for over 70 years, and machine shop owners are abundantly aware of the competitive benefits. By increasing value and reducing the amount of work required to perform tasks on a shop floor, many shops have experienced a transformation that has allowed them to significantly improve profitability and boost sales. A core part of lean manufacturing is the removal of waste from the manufacturing floor. The Toyota Production System identified eight wastes that are understood widely by machine shop managers.
1. Transportation. Nonvalue-added movement of parts, material and information.
2. Waiting. When people, parts, systems or facilities stand idle while waiting for a work cycle to finish.
3. Overproduction. Producing parts more quickly or in greater quantities than a customer
4. Defects. Producing parts so flawed that customers would deem them unacceptable.
5. Inventory. Accumulating leftover raw materials or finished goods that do not contribute to value creation.
6. Movement. Unnecessary movement of workers, material or equipment during a single step or at a single station.
7. Extra processing. Performing additional work even though it is not required to meet customer standards.
With the ever-widening skills gap in the machining industry, shop owners have been even more challenged by the eighth waste.
8. Underutilizing human potential. When employees can make a greater contribution yet are prevented from doing so because of other tasks they need to perform.
The only way that shop owners have been able to combat the final waste is by adding CNC machine tending automation. With robotic machine tending solutions on a CNC machine shop floor, workers have a better opportunity to contribute to the overall manufacturing process. As a result, shops that have embraced and applied this automation find that it is giving a competitive advantage from increased output and capacity. People are doing more cerebral work like programming, scheduling, inspecting and setting up CNCs for jobs. These shops also have benefited from attracting and retaining highly sought-after talent.
