Abstract
The disclosure is directed to an apparatus and method for automated edge finishing using hybrid position/force control of an XY table. The disclosure is particularly directed to learning the trajectory of the edge of a workpiece by "guarded moves". Machining is done by controllably moving the XY table, with the workpiece mounted thereon, along the learned trajectory with feedback from a force sensor. Other similar workpieces can be mounted, without a fixture on the XY table, located and the learned trajectory adjusted
Claims19
An apparatus for automated edge finishing and deburring of a workpiece comprising:
- tool means operable at a fixed station;
- XY table means with a workpiece mounting means
- trajectory learning means;
- XY table position controller means for moving an edge of the workpiece along said learned trajectory;
- and
- force sensor means affixed on said tool means and operatively connected to said controller means.
A method of automated edge finishing and deburring of a workpiece comprising the steps of:
- a) providing a tool means at a fixed station;
- b) providing an XY table with a workpiece mounted thereon;
- c) providing means for learning a trajectory of an edge of the workpiece;
- d) providing means for controllably positioning the workpiece along the learned trajectory;
- and
- e) providing a force sensor affixed on the tool and operatively connected to said controller means.
