The General Process
In order to ensure consistent quality in their production process, manufacturing plants in all industries need to inspect the parts they are producing on a regular basis. For that reason, traditional metrology solutions – ranging from Coordinate Measurement Machines (CMMs), Checking Fixtures, or so-called “Camera Tunnels” – have thus been part, for years now, of the manufacturing process.
Another widely adopted metrology solution is Automated In-line Gauging – also referred to as Robotic Inspection or Flexible Measurement Systems (FMS).
The Automated In-line Gauging Advantage
A Robotic Inspection system is made of four major components. A standard industrial Robot carries a precision small-range Sensor in close proximity to the multiple features to be measured on each production part, thus effectively providing a large measurement envelope. One Robotic Inspection installation can include multiple Robot/Sensor systems. An appropriate Metrology Interface then allows the collected measurement data to be viewed, compared with CAD data, set against pass/fail criteria, analyzed with SPC software, etc. However, considering an industrial Robot’s low intrinsic accuracy combined with the harsh environment of production, adequate Calibration is required at all times to guarantee the maximum measurement performance of the Automated In-line Gauging system.
Compared to traditional metrology methods (e.g. CMMs, etc.), an Robotic Inspection system generally offers the following advantages:
Shorter measurement cycles (relying on the robot’s speed)
Increased measurement flexibility (just by re-programming the robot)
100% inspection capability (system installed right along the production line)
Durability for plant floor environment (system made of rugged industrial components)
The Dynalog Advantage – Performance
Dynalog, the world leader in the field of general Robot-cell Calibration solutions, developed a unique and patented Calibration approach for the specific purpose of FMS applications: the DynaFlex™ solution. Simply put, the purpose of the DynaFlex Calibration solution is to turn an off-the-shelf industrial Robot into a precision metrology instrument. In other words, without Calibration, FMS would simply not exist! Practically, the DynaFlex Calibration routine runs transparently in the background, automatically compensating for any robot deviation with a minimal impact – if any – on the cycle time.
More specifically, the DynaFlex Calibration solution provides two major capabilities:
To guarantee the Robotic Inspections’ Repeatability despite any temperature variations or any other environmental changes (i.e. “Relative Calibration” or “Temperature Compensation”)
To confer true volumetric Absolute Accuracy to the Robotic Inspection system (i.e. “Absolute Calibration”).
An FMS with Relative Calibration allows any changes of a particular production process to be monitored over time. With Absolute Calibration on the other hand, an FMS goes a step further as it provides “CMM-like” measurement data, which can be compared directly with CAD data. The DynaFlex Calibration system also offers the ability to automatically recover the FMS following either an unexpected “crash” or a routine repair of the Robot and/or the Sensor – with little or no operator intervention!
The Dynalog Advantage – Compatibility
Based on your manufacturing experience, you might prefer a specific Robot brand, be more familiar with a certain Sensor type, or have standardized on a particular Metrology Interface… Due to Dynalog’s worldwide acceptance, the DynaFlex Robotic Inspection solution is indeed compatible with a wide range of Robot, Sensor and Metrology Interface Brands (contact Dynalog for a complete list) You, the customer, choose the FMS components you prefer considering such factors as local support, price, performance/functionality, additional training, spare parts, etc. Whatever the mix of components, DynaFlex can provide a high-performance fully integrated Automated In-line Gauging solution!
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...
