Abstract

Within the robotics machining industry, normally a work piece model is first used as a template for creating a robot path. Edges and/or faces are then selected from the work piece in order to create robot path. After polishing or grinding has been made, on-site engineers will have to rework the workpieces manually by processesing the red-marked areas anew.To solve this, we would like to add automatic track coverage for the generated robot paths.Advantages with the mentioned feature comes in terms of time saving, while at the same time yielding better results with improved finish.For operators, it can greatly reduce operation time and spare them extra time used for aftertreatment. This in turn will benefit the factories and stakeholders.

Machining Plus Track Coverage

Robotics Machining Track Coverage

Within the robotics machining industry, normally a work piece model is first used as a template for creating a robot path. Edges and/or faces are then selected from the work piece in order to create robot path. Below is an example of a work piece, where we have a planned robot path for the tool (Figure 1). The tool in this case can be both a grinding wheel or a polishing wheel.

Figure 1 - Work piece with robot path

When this work piece is being worked on (Figure 2), it will leave traces from the grinder or polisher, which will appear as higher elevations at the edges of the tool (Figure 3). Here we have marked the area that has been processed as green and elvations as red.

As of now, after polishing or grinding has been made, on-site engineers will have to rework the workpieces manually by processesing the red-marked areas anew.

To solve this, we would like to add automatic track coverage for the generated robot paths (Figure 4). The brown line indicates another set of robot paths and the green line a second set of added paths. These are generated automatically based on the original robot path(s) and the tool shape and size. These are all used to cover up the edges created by the grinding or polishing wheel (marked red in Figure 3).

Note that we will al...
