Motion Control with Precision Noncontact Displacement Sensors

Introduction Noncontact displacement sensors are used in measurement applications where surfaces or processes do not allow contact and demand high precision. Capacitive, confocal, eddy-current and laser triangulation sensors have proven themselves in applications that incorporate motion systems. Noncontact sensors are available in many different versions. However, sensor range decreases significantly as the required precision increases.…

Customized Relationships and Coordinated Motion with StatusGetAxisItemFast()

Many applications require custom coordinated relationships between a system parameter or ancillary motion equipment and the motion of the primary machine mechanics. Likewise, it is common to need custom kinematic transformations between a virtual programming coordinate frame and that of the real mechanics. Aerotech’s AeroScript programming language includes the StatusGetAxisItemFast() function as an ideal tool…

Top 3 Ways to Increase Your Positioning System’s 3D Accuracy

Positioning systems are used to automate almost every high-precision manufacturing process. Many of these processes occur in 3D. Some examples include positioning a part’s surface in 3D to be 100% inspected and laser cutting a feature along a complex 3D path. For these types of processes, it’s exponentially harder to achieve manufacturing tolerances in terms…

Improving Automation Performance

At some point automation hardware inevitably becomes obsolete. It’s hard to know exactly when to retrofit or redesign, but there are indications that cannot be ignored. Quite simply, when the system’s tolerances and throughput can no longer meet market demand, it is time to upgrade. If the tolerances of the previous generation system can only…
