Abstract

The early KC machines and the current C:NC utilise the same standard programming of G&M codes formalised as the IS0 6893 standard to machine parts with complex shape in a precise manner. However, the G&M code contains implicit technical information and does not meet the requirements of modern NC technology as it uses low level codes to describe tool movements and instructions. Literature shows that the current CNC is difficult to manage, modify and verify NC data easily. IS0 14649 referred to as STEP-NC is the result of an international effort to achieve full interoperability and bi-directional information exchange throughout the manufacturing network. STEP-NC: has been designed in such a way that information remains in its context and without reducing to primitive instructions such as G&M code. This research will explore IS0 6983 (G&M code) together with IS0 14649 (STEP-NC) and utilise STEP-NC in overcoming the problems of G&M code and at the same time take advantage of current advances in computing and controllers. A new STEP-NC code generator (<;EN-MILL) which focuses on the milling process that is able to generate STEP-NC codes based on Example 1 in IS0 14649 I'art 11 was developed. The advantages of the proposed STEP-NC code generator (GEK-MILL) program was verified and evaluated by comparing the output generated by the software with IS0 14649 Physical File for Example 1. The STEP-N'C code generator (GEN-MILL) can understand and generate STEP-NC codes through a STEP-NC compliant interface and will give industries and academicians more in-depth understanding and confidence to switch from G&M code to STEP-NC.
