Conomatic Automatic Bar Machine

The following MasterTask lesson outline indicates the tasks needed to act as a machinist on Conomatic automatic bar machines. Because of the performance-based approach to training utilized within MasterTask systems, the outline below indicates what a trainee will be able to DO after completing each part of a lesson. Some of these tasks require the trainee to explain how something works to insure they have the required understanding of the processes and are not simply memorizing procedures. All of the tasks listed will be a part of the Performance Test within each lesson. To learn more about these tests and the training process itself, review The MasterTask Concept and Course Materials.
