Cloning of production lines
To avoid having to repeat the complex measurement for a second cell for deburring turbine blades, the robot cell is to be cloned.
Wiest advantages
Customer benefits
The programmes of the master cell were easily transferred to the cloned cell.
At the same time, both installations could be secured by measuring them. Replacement of fixed cutters can be geometrically mapped by re-measuring with LaserLAB. This ensures that the milling programmes function correctly.
Integration on the second line without reteaching
Increase availability
Prevention of downtime
Shortening the commissioning
Case
Cell description
In the customer’s robot cell is an ABB IRB 4400, which deburrs turbine blades for aircraft engines. The parts are gripped, placed in a positioning station and gripped again. The robot then deburrs the parts at a milling station consisting of several fixed cutters. The robot then moves the parts to a brushing station as the final processing step. Once the parts are finished, they are placed in a magazine.
Task
The robot programme for deburring turbine blades is extremely difficult to create. The key criteria are the specific radii that the blades must have. In the end, an acceptable result could only be achieved by measuring the blades and then reprogramming them in tenths of a millimetre. This process had to be repeated several times.
To avoid having to repeat this process for the second milling cell, the customer ordered the robot cells to be cloned.
Implementation
The robot was equipped with a manual tool change system. An adapter plate was supplied that could be fitted with either a single measuring rod for robot calibration with loop:in or with LaserLAB for measuring the cutters.
For the cutters, a measuring rod with a 6 mm pin was made to hold the chuck. The measuring rod is designed so that the centre of the ball coincides with the tip of the cutter.
