Many factors affect the Life Cycle Costs (LCC) of power assembly tools for threaded fasteners. These include procurement, installation, operating costs, and maintenance costs. Each particular assembly application will have unique factors affecting the LCC of the assembly tool used.
When choosing between pneumatic and electric powered tools, it is seldom an “apples-to-apples” decision. Most of today’s electric tools provide dynamic torque monitoring and networking capabilities as part of the standard fastening system, whereas most pneumatic tools can be purchased without instrumentation. One must also consider the differences between replacing existing assembly tooling in a plant where the utilities are already in place, versus a new plant installation, where the power source choices may offer cost avoidance opportunities.
Here we look at only the energy consumption necessary to operate each type of tool for a typical threaded fastener assembly application in an auto final assembly plant. The energy cost comparison method can be used to estimate the energy consumption costs of any other assembly application and it can be extended to estimate plant-wide energy consumption for an entire population of assembly tools.
