To determine the transformation from the workpiece into the coordinate system of the robot the software carries out the measurement of component stations or external stationary tools.
base:in is the Wiest software component that enables you to accurately measure a base or a work object at any time. Once you have determined your base coordinate systems, you can repeat the measurement at any time in order to adjust to mechanical alterations in your cell. Use it to minimise your setup times or rework times when a cell is relocated. Just like tool:in, the base:in software can also be used for cell backup.
The goal of measuring the robot base (base measurement) is determining the transformation from the workpiece into the coordinate system of the robot. This is especially important for offline programming, duplication of the robot programmes, as well as relocating of robot cells. With base:in you can exactly measure the component holding fixtures (stations), as well as external, stationary tools e.g. electrode holder and gluing jets.
Attach the measuring system LaserLAB to the robot hand and screw the measuring rods into the provided mating bores in the working space of the robot. Now measure the measuring balls by running a teach-in robot
programme or moving the robot manually. The searched transformation can be calculated on the basis of the measured values, which then can be transferred into the robot control by pushing a button.
Furthermore, you can measure stationary electrode holders and determine their movement direction by using the WIEST-measuring triangle or the WIEST-measuring beam. The measuring sequence stays the same.

The measuring models M1-M6 are available to you for base measurement. The measuring model is selected individually depending on the base you want to measure.
This measurement model is used exclusively for measuring spot welding guns. The corresponding measuring device for this is the measuring bone. The measurement result provides the coordinates at the centre between the two balls of the measuring bone, in other words the external TCP of the spot welding gun without orientation.
The measuring triangle is the device used for measurement model M3. The measuring triangle is attached to the base you need to measure or is held by it, and the three balls are measured. The centre of the triangle is the origin of the base coordinate system. The first ball defines the positive X-axis, from the centre of the triangle. The surface normal is the positive Z-axis. The base coordinate system can be adjusted if necessary by displacement along the Z-axis and rotation about the Z-axis.
Model M4 is the universal measuring model. Short or long measuring rods can be used for this. These are either screwed directly into adapter blocks on the base or into a setting master. The ball positions are determined beforehand in relation to the required point of origin of the base. If the four balls are now measured, the required base coordinate system is calculated from the relationship between the defined ball positions and the measurement results.
The positive Z-direction of a base can be measured directly with the M5 model, the measuring beam. Two balls are measured, one after the other. The first defines the origin, the second the positive Z-direction starting from the origin. The measurement result can be shifted along Z and rotated round Z later.
The M5 model is particularly useful for measuring machining centres with rotating tools such as spindles, milling cutters and cutting blades.
Model M6 implements what is called the 3-2-1 method for measuring a base. The balls are screwed on to the base and measured. The first ball defines the point of origin. The second ball defines the positive X-direction (from ball 1 to ball 2) and the third ball gives the positive X-Y half-plane.
