The choice between numerical (CNC) and conventional machines may be in many cases a hard task. In the present work a practical method is introduced to choose either CNC or conventional machines based on a scoring system that evaluates the technical aspects in each case. The system considers 15 factors that affect the decision-making and for each factor it is assigned a weighing value. These factors are grouped into 3 blocks describing the nature of the product, the nature of production and the existing facilities in the working place. Based on the final total score, a selection decision can be made. A case study is presented where the scoring system has been employed applied to it.
