In this thesis, an actuation system is developed for a Two-Axis Gyroscopic (TAG) adapter.
This adapter is a fixture with two auxiliary axes which is used for the Single Point
Incremental Forming (SPIF) technique to enhance a three-axis mill to have five-axis
capabilities. With five-axis mill capabilities, variable angles between line segments of the
toolpath and the tool can be obtained. To achieve specialized angles between a line
segment and the SPIF tool, the sheet is rotated. Inverse kinematic equations for the TAG
adapter are derived to calculate the required rotations for the TAG adapter’s auxiliary axes
for a line segment of a toolpath. If the next line segment requires a different orientation of
the sheet, the sheet is rotated while the tool follows the rotation of the sheet to maintain its
position at the connecting point of the line segments of the toolpath. Five equations of
motions are derived to calculate the three translations of the mill and two rotations of the
TAG adapter’s frames, during forming. A toolpath execution algorithm is implemented in
MATLAB which uses the five equations of motion to execute a toolpath. The algorithm
generates an array of data points that can be used by a Computer Numerically Controlled
(CNC) machine to follow a desired path. A visual representation for the execution of the
toolapth is implemented in MATLAB and is used to illustrate the successful completion of
a toolpath. A computer controlled motor system is selected and tested in this thesis which
will ultimately be integrated with a worm gear system and a CNC machine to develop a
full CNC actuation system. / UOIT
