Write G Code program that can cut shapes from a 100cm long by 50cm high by 5 - 20 cm thick blocks of polystyrene.
Shapes range from circles, squares, rectangles to flowers, hearts etc.
As many shapes as possible should be cut from the block to save material.
Tool paths must be designed so that the hot wire would not exit a finished shape at the bottom to avoid excessive melting of the material. There should be at least 5mm between the edge of the block and the cut shape to allow for size variances in raw material.
The following programs are needed:-
Circles - 40cm, 45cm
Squares - 30cm, 35cm, 40cm, 45cm
We will need other shapes too if this work is done well. We'll need flower, heart, oval etc.
I've attached an example piece of code for 10cm circles.
