Robotic cells are designed for high-precision measurements of geometric parameters (diameters, linear dimensions, chamfers, runout, alignment, etc.) of various bodies of revolution.
The core of the cell is the RF657.2D Series 2D optical micrometer, which actually controls the entire measurement process. The micrometer is equipped with a rotating table with a vacuum clamp, on which the robot places the part to be tested.
To implement the project, we significantly expanded the micrometer's functionality. The following Smart-blocks were added to the micrometer’s software:- "CiA 402 Motor" is a stepper motor driver control unit that complies with the CiA 402 protocol and EtherCAT interface. It is designed to control rotary tables and/or linear parts feed systems;
- "OPC UA" is a block implementing the server part of the industrial protocol OPC UA for two-way data exchange between external client systems (SCADA, MES) and internal blocks of the computing circuit;
- "S7 client" is a block implementing the client part of the S7 industrial protocol for two-way data exchange between external Siemens controllers (S7-300/400/1200/1500) and the internal computing circuit;
- "Classifier" is a block for automatic recognition the part type based on the input profile or contour. Classification is performed based on parameters specified in a JSON file, after which the program automatically selects the appropriate part measurement algorithm;
- "Runout & Concentricity" is a block for automatically measuring the radial runout, total radial runout, and coaxiality (concentricity) of a part profile relative to a specified reference surface. Measurements are performed while the part is rotating.
Thus, the method of programming a measurement algorithm based on the use of ready-made Smart Blocks allows for the rapid creation of a virtually unlimited number of measurement functions, the measurement of products of varying complexity, and the automation of measurements by organizing interaction with robots and control systems.
