The goal of this research is to develop energy consumption and
manufacturing cost models for the micro-drilling process on printed
circuit boards. As mentioned above, micro-scale machining is
very difficult to control the performance precisely. In order to
assess impact of each component, the energy consumption of each
machine module is identified and modeled using measured data.
The drilling characteristics are described in terms of process parameters,
and the resulting model is verified. The manufacturing
cost model is based on the tool and energy costs. Integrated
consideration of the total cost for each component is required,
including the tool and material usage, particularly for micromachining.
The measured data fit the constructed model well,
and thus the model is applicable to developing a process planner
based on energy conservation or cost-saving strategies
