One obvious goal of making a RepRap replicatable is getting it to make it's own PCBs or other electronic circuitries. PCB milling is one of the more promising ways of Automated Circuitry Making.Recent firmwares understand a pretty standard flavour of GCode, opening the door to a lot of toolpaths already existing.This page describes a few promising ones.
HYDRAULIC CIRCUIT DESIGN AND ANALYSIS A Hydraulic circuit is a group of components such as pumps, actuators, and control valves so arranged that they will perform a useful task. When analyzing or designing a hydraulic circuit, the following three important considerations must be taken into account: 1. Safety of operation 2.

To make the Etching process faster, you can either stir the solution (with PCB dipped) in every 2-3 minutes or you can use some warm water to make the solution. Step 8 Now rub the PCB with the steel wool or fine sand paper to remove the black ink, or you can use thinner (Acetone) on a piece of cotton to remove Black ink.

MILLING OPERATIONS Milling is the process of machining flat, curved, orMilling machines are basically classified as vertical or irregular surfaces by feeding the workpiece against a rotating horizontal. These machines are also classified as knee-type, cutter containing a number of cutting edges. The milling ram-type, manufacturing or bed type ...
Copper Mining & Extraction Process Flow Chart. This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process. Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore).
Rice Milling 3.3 Multiple pass rice milling Commercial Mill The milling process in larger commercial mills combines a number of operations that produces higher quality and higher yields of white rice from paddy or rough rice. The process involves: 1. Pre-cleaning the paddy prior to milling 2. Removing the husk or outer layer from the paddy 3.
The AG mill circuits have not been able to sustainably achieve the design capacity of 30,000 t/d of underground ore. Thus, a fraction of the underground ore is diverted to the conventional circuit. The conventional circuit consists of crushers, rod and ball mills and traditionally has achiever lower copper recoveries than the AG circuit.
•Work on a milling machine is most often held in a vise clamped onto the bed. To make features aligned with the edges of the stock, it's necessary to align the vise with the feed axes of the mill. To do this, mount the vise on the bed and secure it with T-bolts, but only lightly so as to permit adjustment of the orientation of the vise.

A flow-control-and-check valve used in this circuit would allow reverse free flow. A meter out speed control circuit is shown in Fig. 16.2. 16.2.3 Bleed Off Speed Control. In this type of circuit flow control valve is not directly provided in the feed line but is connected to the pressure side as shown in Fig. 16.3.
The Model 20 has similar capability in terms of particle size to the Fluidized Bed Jet Mills. This closed circuit combines the particle-to-particle impact of opposed jet fluid energy milling with high efficiency classification, resulting in the production of steep distributions with close top size control.
