STEP compliant NC for interoperable manufacture of turn/mill discrete components

This paper reports ongoing research on the application of new standards for CNC machining to enable quality assured customised part manufacture by implementing the new standard, ISO 14649 otherwise known as STEP-NC. The paper focuses on the use of this new standard, to address the process planning and machining of turn/mill discrete components. Today complex turn/mill components can be produced on a wide range of turning centre configurations with multi axes, twin spindles and dual turrets. Due to the complexity of programming there is a need to model their process capability to improve the interoperable manufacturing capability on machines such as turning centres. This paper proposes a STEP Compliant NC structure for generation of ISO 14646 code which can be used for turn/mill component manufacture.
