At last, the power is in our hands. We have a working TriPO prototype. The graph below shows force, torque and power measured (computed) from the data for one revolution. Starting at bottom dead position, the greatest force is around 130 N, torque 22 Nm, and average power for the whole revolution 22 W. This might […]
We updated our Cene the CNC Guide with discoveries we made during our prototyping work. Among them are some that we think may spare you a few hours. Hardware and software setup, cutting parameters, … There is just too much stuff to write all here. You should download the whole package below – it includes:
Edit February 12nd, 2016: there has been an update to this post. Since we adopted Cene the 3040 4-Axis CNC, we’ve been working with it and on it. We added a few hardware improvements such as limit switches, tool length probe, LED lighting, closed coolant pump container, just to name a few. We have set
Beauty is hidden in the details, but not many people can find it. That’s why Chaotic-Tock has so huge gears. Usually, these elements are hidden from view, and even if they are visible, they are usually so tiny that details can’t be seen at all. But when gears are visible and big enough, they look
Calibration of a sensor means finding out a few parameters that are needed to convert raw readouts to actual results. A single sensor needs a few numbers. It is attached to a high-precision-high-complexity-high-price device in a calibration laboratory and a number of measurements is made to obtain the parameters. It takes time, money, knowledge and
There is a box of shame in our workshop that contains a number of more or less (but mostly less) successful attempts at building a decent prototype of force sensor. We never throw away anything because of one single reason. The funniest thing in the world is seeing how insanely stupid your former self was.
About Knof Knof is a common name for our family of force sensors. All of them are small, tough, accurate, extremely simple and therefore cheap. The main advantages are: simple design that requires no complex manufacturing techniques and no exotic materials small size with regard to given maximum force high overload tolerance wide range of
It’s the little details that usually ruin everything. When some tests failed they just confirmed what I always suspected wouldn’t work but sometimes there was a totally unexpected inconvienience waiting for us. Once upon a prototype, we had this incredible idea. A force sensor would be much like a sandwich, a thin layer of soft
