![]() In addition, a traffic light can signal that a measurement sequence is in process or completed.ĭepending on the size and complexity of the part, it may not be necessary for the robot to place the part on the measuring machine, move aside, then return to pick up the part. Depending on the outcome of the measurement, acceptable parts can be placed or dropped into the “good” tray and out-of-tolerance parts can be placed or dropped into the “reject” or “rework” tray. In addition, the measuring system can trigger the robot to return and pick up the part at the end of the measurement routine. Programming of the robot can trigger the measuring system to initiate a measurement sequence as soon as it moves away from positioning the part. Individual parts can be picked up from a tray or box, moved to, and positioned on a measurement system. In the simplest case a robot or cobot can be fitted with an end effector designed specifically for the part being measured. There are numerous implementations of automation for part handling with automated measuring systems. Although measurement of those parts can be fully automatic once they are on the measuring machine, the overall throughput can be improved, and associated costs reduced using robotic and motorized pallet loading and unloading under program control. Many SmartScope systems are operated on multiple shifts measuring batches of parts loaded on and removed from the systems by their operators. Any out of tolerance dimension is flagged for rapid, visual acceptance testing. That range of technologies allows numerous features of various sizes and resolutions across any surfaces of the part to be measured without operator intervention. With a versatile multisensor measuring system, optical imaging, laser scanning, and touch probing can all be part of a single measurement process on a single machine. Simply load a batch of parts on to the measuring machine and press the start button. In those environments the machinist who makes the parts measures them too. CNC measuring machines such as the OGP SmartScope range of multisensor metrology systems from Quality Vision International, automate the measurement of parts brought to the systems, which can be right in a work cell. Today manufacturers want to have the measurement process close to where the parts are being made. No longer is it acceptable to have parts queued up outside a quality lab while production schedules are tight. ![]() Automation of the inspection and measurement of the parts while in-process or post-process provides a number of benefits that relate to increased productivity across the supply chain. Numerous measurement technologies are used for quality control and process monitoring in today’s manufacturing environments. No matter how accurate the tools are for making parts, their important dimensions need to be verified to ensure they meet quality expectations, so they will fit and function appropriately as parts of higher level assemblies. By Fred Mason, Senior Vice President of Marketing for Quality Vision International, the parent company of Optical Gaging Singapore Pte. This is where use of CNC measuring systems that include automation of part handling can keep up with those demands. With management focus on minimising costs and maximising throughput, manufacturers would want to avoid any bottlenecks from the measurement process. A critical part of a manufacturing process for such parts is verification that they comply with the specifications on their design drawings. As machine tool technology continues to evolve, it is possible to create intricate, detailed parts from a wide range of materials.
