Abstract

A portable machine includes a controller to receive target parameters associated with a workpiece to be worked. A front assembly includes a first baseplate which is stationary during operation, a first actuator to controllably move the workpiece bidirectionally along a longitudinal axis thereof, a second actuator to controllably rotate a second baseplate relative to the first baseplate, and at least one tooling unit. A rear assembly includes a third baseplate with a rolling base, a fourth baseplate rotatably coupled to the third baseplate, and a rear workpiece clamp. Sensors generate signals representing a distance between the first and third baseplates, an orientation of the first baseplate relative to the second baseplate, and an orientation of the third baseplate relative to the fourth baseplate. The controller generates control signals to the tooling unit and the first and second actuators based on at least the target parameters and the sensor signals.

Dependent claims

A method of operating a portable machine for working a workpiece comprising the steps of:

continuously measuring a distance between a front assembly and a rear assembly;
generating control signals to a first actuator configured to move the workpiece in a first direction or an opposing second direction along the longitudinal axis, the control signals indicating the direction and distance to move the workpiece based on at least predetermined target parameters for working of the workpiece and the measured distance;
measuring a first orientation of a first baseplate of the front assembly relative to a second baseplate of the front assembly;
measuring a second orientation of a first baseplate of the rear assembly relative to a second baseplate of the rear assembly, wherein the first and second orientations correspond to rotation of the workpiece during the working thereof;
generating control signals to a second actuator configured to rotate the second front assembly baseplate relative to the first front assembly baseplate in a first direction or a second opposing direction about the longitudinal axis, based on at least the predetermined target parameters for working of the workpiece and the measured first and second orientations;
predicting a stability of one or more of the front assembly and the rear assembly, based on a determined weight and/or configuration of the workpiece further in combination with a determined weight and/or relative position of the front assembly and the rear assembly;
and
wherein one or more of the control signals to the first actuator and the control signals to the second actuator are adapted corresponding to a predicted stability being outside of one or more defined bounds.
