Read MoreThe Difference Between Stage-on-Granite and Integrated Granite Motion Systems
The selection of the most suitable granite-based linear motion platform for a given application depends on a host of factors and variables. It is crucial to recognize that each and every application has its own unique set of requirements that must be understood and prioritized in order to pursue an effective solution in terms of…
Read MoreMachine Positioning Uncertainty with Laser Interferometer Feedback
The purpose of this discussion is to explain the major contributors to machine positioning uncertainty in systems with laser interferometer feedback near the work point. We will use an example to quantify these uncertainties in a real implementation of a laser-feedback-driven machine. Laser interferometers are used as a measurement reference for machine correction and accuracy…

Read MoreLaser Raster-Scanning Patterns on Cylindrical Workpieces Using CADFusion and PSO Bitmap Tools
A large number of cylindrical laser processing applications program the laser writing campaign as if the two axes (one linear and one rotary) are both, in fact, linear in nature. In other words, the cylindrical pattern is “unrolled” to make the shape a more typical flat workpiece. While this technique might ease the motion control…
Read MoreHarmonic Cancellation Algorithms Enable Precision Motion Control
The internal model principle of control theory states that algorithms designed to perfectly reject input signals must contain a model of that input. Feedback control that adheres to this internal model principle has led to the development of harmonic cancellation algorithms and even more complex repetitive controllers. How Are They Useful? Periodic disturbances are commonplace…
Read MoreSynchronizing Position Synchronized Output (PSO) with Mode Locked Lasers
Many lasers are limited to firing pulses based on an internal clock source and cannot be asynchronously triggered from an external signal such as Aerotech’s Position Synchronized Output (PSO) feature. One approach to working with this laser type is to set the pulse width of the PSO output to be the same as the period…
