Maintain your Robot's Accuracy throughout Production - Incl.:

Duplicate Robot Programs with No Touchup - Incl.:

Robots have historically been taught manually, i.e. using the robot's 'teach pendant' to manually drive the robot's TCP to the desired point along the part to be operated on, while visually verifying – as much as feasible – the achieved accuracy. This is obviously a time-consuming process, to be painstakingly repeated for each (relevant) point along the robot's path in space; furthermore, this process clearly doesn't...[more...]

Whether a particular robot-cell has been initially put in service using traditional manual robot programming methods (with the teach pendant), or through Off-Line Programming Simulation-based techniques, that robot-cell might need to be duplicated. This is often the case when the level of production output requires multiple 'identical' robot-cells to perform the same task. Instead of painstakingly reprogramming...[more...]

Whether a particular robot-cell was originally programmed manually, or through Off-Line Programming (see "Off-Line Programming with No Touchup"), it is imperative to maintain the positional accuracy of these original robot programs throughout production – despite the many hazards encountered on any plant floor: for example...[more...]

Minimize Robot Downtime

Those same 'Recovery' calibration tools allowing one to maintain a robot-cell's initial Absolute Accuracy (see "Maintain your Robot's Accuracy throughout Production") offer an additional critical benefit: reduce robot downtime – following a sudden tool crash, replacement of a worn out transmission mechanism, replacement of a robot motor, etc. – to a minimum!
The roPOD™ and the AccuBeam™ systems are In-Line Recovery Calibration...[more...]

Off-line Programming with No Touchup

A robot is generally capable of repeating the same move towards a specific point in space, over and over, within a high level of tolerance (referred to as 'unidirectional Repeatability'), generally well below 0.1mm. But this does not mean that that particular point in space is well known relative some global coordinate frame (such as the robot base frame): the level of 'Absolute Accuracy' achieved by an 'off-the-shelf'...[more...]

Accurate Cutting, Sealing, Welding with your Robot

Robotic applications such waterjet cutting, laser cutting, applying a bead of sealant, arc-welding, etc. are generally 'path-intensive', in that such applications require the Robot's TCP to accurately follow a specific path along a part (located on a fixture), and that such path is often formed by a series of points at a rather close distance from one another (depending on the path's shape). Such paths are typically good candidates for Off-Line Programming: the part, and the desired...[more...]

Turn your Robot into Precision Machining Equipment

Manufacturing plants in all industries require ongoing inspection of their production parts, to monitor consistency and quality of the production process. Typical part features to measure are the diameter and the location of a hole (circle, slot, etc.), the location of an edge, the distance to a surface, the location and length of studs, etc. Historically, off-line measuring systems, such as CMM's, have been used to measure random part samples removed from the production...[more...]

Robot Performance Analysis

One typical issue to deal with in various robotic applications is the variation from part to part of the location of the fixture holding the part the robot is operating on; another typical case is simply the variation of (the location of) the part itself within the fixture. So, while robot calibration can accurately compensate, at the launch of the production line, for errors in the 'metrological chain' formed by the robot, the end-effector, the fixture, and optionally external axes and/or a positioner...[more...]

Targeted Robot Communication Solutions - Incl.:

Some robot applications require the highest possible accuracy – close to the robot's repeatability, i.e. typically < 0.1mm – which robot-cell calibration alone cannot achieve, especially in the case of external dynamic forces (e.g. the pressure exercised by drilling). The required accuracy should be achieved not just at the robot's final resting position (as is the case in Robot Guidance – see "Robot Guidance for Part-to-Part Variation") but along the entire path followed by the robot's...[more...]

Automated In-Line Gauging

Drilling, Routing, Trimming and other machining operations are high-force applications historically handled by dedicated equipment, such as CNC's. To increase flexible manufacturing and to reduce cost, robots are more and more used in such applications, with heavy sophisticated end-effectors mounted at their ends. Aerospace is one industry in particular where such installations are becoming prevalent...[more...]

Robot Guidance for Part-to-Part Variation

In today's world of flexible automation, end-users must be able to rely on the performance of their robot when executing various programs and applications. The ISO 9283 International Standard and the RIA 15.05 Standard define the performance criteria and related testing methods to quantify performance characteristics of manipulating industrial robots. These criteria and tests assess the static and dynamic performance of a robot...[more...]

Adaptive Robot Control for Ultimate Accuracy

Most of Dynalog's products require a solid communication line and reliable integration not only with the robot controller, but with other equipment as well, such as with numerous measurement devices, with different PLC's, and with customers' data servers. The need to 'Filter' robot programs with the...[more...]
