I need a person with a sharp brain

mardi 30 décembre 2014

I have a new tool for my CNC.

It is a springloaded engraver.

I need to work out how much to turn the screw (1) to equal a force of 500 gram upwards of the plate (10)

I do not need to know how much weight to pull the plate down, I need the upwards pressure (resistance) on the spring.



In other words, that is the pressure I need for the bit to follow any unevenness in the material.

The plate will be resting on he top of the bottom (u-shaped) part of the tool.

The router is resting in the hole (10)
