MMD-200
Brand New Precision Measurement Instrument
The Six-Dimensional Motion Measurement Device (MMD) is an innovative product of LEI & SO Co., Ltd. The MMD is designed to measure the motion of the tool relative to the workpiece on a machine in shop floor. The measured motion is six-dimensional, including three translations and three rotations.
Once the MMD is installed on a machine, it can be used for all kinds of measurements and inspections such as the calibration of DH kinematic parameters of an industrial robot, the calibration of link parameters of the two rotary axes of a five-axis machine tool, the tracking of dynamic motion errors and the measurement of thermal errors of a main spindle.

BBB-080
Planar Contour Measurement
The Ball Bar Box (BBB) is a 2D contour measuring system using two optical scale ball bars. After installing two ball bars on the table of a machine tool, the CNC controller drives the table to move relative to the tool on a 2D plane according to a NC test program. The BBB system measures the lengths of the two ball bars and computes the actual positions of the tool. After the measurement, the dynamic motion errors of the machine tool can be obtained by comparing the actual contour and the ideal testing paths.
