Enabling Machining Vision Using STEP-NC

Abstract

STEP-NC is a new data format for manufacturing control. One of its applications is to enable integrated on machine measurement of machining processes using vision systems and other sensors. In this paper we describe the manufacturing process and manufacturing resource models in STEP-NC that can be used to enable this type of measurement. These descriptions include the machine setup so that the configuration of the part can be identified and corrected, the machine kinematics so that the actions of a machine while adding or subtracting material can be verified, and the product tolerances so that the quality of the final part can be predicted and corrected during the machining.

A novel methodology for cross-technology interoperability in CNC machining

“…The CNC interoperability research started with developments in manufacturing technology and processes by Suh and Sheon in terms of a proposing a framework for intelligent CNC systems [15], this framework was followed by Hardwick as the first outlook for implementation of STEP-NC [16]. Consequently, a five-axis milling machine that accepted STEP-NC input was designed by Lee and Bang [17] and another prototype was proposed by Newman et al with a STEP-Compliant CAD/CAM system using ISO 14649 [18].…”

Modelling and implementing circular sawblade stone cutting processes in STEP-NC

“…STEP-NC programs can be described as a set of complex and structured tasks (workingsteps) to machine the features of a workpiece [25]. Figs.…”

A web-based CAD/CAPP/CAM system compliant with the STEP-NC standard to manufacture parts with general surfaces

“…With regard to the variability and complexity of the parts to be produced by manufacturing companies, machining surfaces and pockets with general shapes requires a long time, and causes many errors. One of the main objectives of the development of STEP-NC is to streamline the design and manufacture of such parts [8].…”
