Application No. 08/434,010
(1) attaching the measurement arm of a passive three
dimensional coordinate measuring machine (CMM) having multiple
degrees of freedom to a multi-axis device and operating the CMM
through a selected 3-dimensional path or operation which emulates
the desired preselected programmed path or operation of the
multi-axis device;
(2) developing 3-dimensional data of at least one of (a)
position and (b) orientation from step (1) and storing said data,
said data defining the actual path or operation of the multi-axis
device;
(3) comparing the actual path or operation to the desired
preselected programmed path or operation;
(4) generating an error map comparing the actual path or
operation to the desired preselected programmed path or
operation; and
(5) using said error map to improve the repeatability and/or
precision of the multi-axis device.
