Maximum electrical power and general requirements

The machine needs to be run from the electrical system within the workshop. This is a 240v 30A supply. However there is also a 2.25 KW compressor on the same circuit.

total power = 240*30= 7200w

This leaves 4950W available for the machine in its entirety.

The machine should be an automatic tool changing mechanism. The simplest way of performing this would be to add a stationary rack at the end of the table. The machine would then center over the top of the tool in a suitable holder. The Z axis come down to the tool holder and draw the tool holder and tool into a spindle. This will thus require pneumatics or hydraulics of some description.

Maximum tool size required in diameter: 13mm shank. This is partially dictated by the high spindle speeds as a result of MDF being the primary material being worked. But also as a function of the machine. Parts will be nested into a sheet and multiple parts cut at the same time. Therefore having a large cutter will be wasteful of material.

The machine needs to provide storage of some description of items like the compressor due to its foot print within the workshop.

The machine needs to be of a horizontal orientation despite the fact the this requires a larger foot print. However it does provide a lower center of gravity and thus is safer. It also allows materials to be easily loaded and positioned for clamping.

As this machine will be horizontal table height should be comfortable to lean across and position fixtures and other items. Work benches are around the correct height for this.

Many work benches are 900mm from top surface to floor. This will make for a suitable height.

The machine should have an accuracy of +/- 0.5mm in MDF and +/- 0.1mm in 6061 T6 Aluminum.

Smaller tolerance and repeatability would be beneficial. These are maximum theoretical values.
