MACHINE DESIGN

We took MTM reconfigural modules as our reference to build the mechanism of our machine. The link to the project is here.

2. Next I made a test module from the MTM files itself and also generated 3d assembly from those files. Once the file was ready, Siddharth put it to CNC and I assisted him.

3. This gave us clarity about our own machine and we decided to use threaded rods for 1 direction and belts and pulley system for the other 2 direction. This decision was taken since we wanted faster movement in the vertical plane (x-y direction), so we opted for belts and pulleys system and the Z axis will be usually used for contouring so we could do with a slower but more precise system.

This is the assembly of the vertical plane system where we used belts and pulley. We realized that we can reduce a lot of weight by making it hollow which will help decrease the load on the threaded rod system below. Hence we designed a pattern which will also look aesthetically good and meanwhile serve the purpose of weight reduction. These frames were supported by triangular members at the corners to maintain Right-angle.

This was CNC file prepared in Rhino for milling. All the joineries were designed foro press-fit junctions to ease the process of assembly.
