Compressed air is used in almost every industry you'd care to name. It's so flexible and useful that industry contacts sometimes refer to it as the "fourth utility."
Successful design of a compressed air system requires correct sizing all system components. This section provides information for designing the following system components
This tutorial is designed to assist the do-it-yourselfer with performing automobile repairs. It is structured around problem areas, such as "my car won't start", encapsulating the problem area with an overview of the diagnosis and repair.
Before bringing in a laser-calibration solution, consider the following steps involved in a machine-tool "tune-up." Machine-tool calibration starts with the geometric alignments—level, flat, straight and square
The first step on the road to knowing that parts coming off the machine meet specifications is ensuring in advance that the machine itself is capable of the desired accuracy.
Whenever one of the three lead screws changes its direction of rotation, the slideway it drives should begin to move immediately. This is the ideal situation. In reality this does not happen.
Most American style hybrid and contractor saws are constructed in a similar way, so if you need to align your table saw, this article may provide some useful tips.
Backlash in the X and Y axis of machining centers is most obvious when milling full circles. If any backlash exists, there will be a nasty witness mark on each quadrant line.
sources of the backlash on a given axis: Leadscrew & Nut, Leadscrew and/or Nut Mounting, Motor Drive Mechanism, Slideways and or Gibs, Machine Flexure and Rigidity
The procedure for doing reverse dial indicator alignment is not a difficult one. There are several steps which need to be taken for a successful alignment job
Make the following measurements of a motor of known dimensions to an accuracy of 0.0001 inch: shaft radial runout, inner bearing ring face runout, and outer bearing ring face runout.
Dial-indicators have been extensively used to check the machine geometry accuracy. However, because of the low resolution and the mechanical contact, its application for precision measurements are rather limited.
The test consists of questions relating to Fluid Power Fundamentals, specialized fluid power topics, ladder logic, system integration, and electrical control technology.
They eliminate the need for complicated systems of gears, cams, and levers. The fluids used are not subject to breakage as are mechanical parts, and the mechanisms are not subjected to great wear.
In order to avoid any damage due to ignorance, this document prepares the user for proper care and installation of the hydraulic equipment related to servo-valve controlled systems
By following an organized step-by-step testing procedure, the problem can be traced to a general area, then if necessary, each component in that area can be tested or replaced.
The golden rule of servo safety is cleanliness. Never assume anything is clean enough until you prove it. Any disassembly or modifications to the hydraulic system between the filter and servo-valve calls for a full scale flushing operation described
Optimal properties of hydraulic oils are achieved by a combination of a base oil and additives (anti-wear additives, detergents, Additives in lubricating oils#Anti-oxidants, anti-foaming agents, rust and corrosion inhibitors etc).
One of the most important requirements to consider for optimum operation of any hydraulic system is quality and cleanliness of the hydraulic oil. The cooling of the oil is accomplished by the proper design of the reservoir and efficiency of the heat exchanger.
The MathWorks SimHydraulics diagram from Simulink. Simulink is an environment for multidomain simulation and Model-Based Design for dynamic and embedded systems.
TrackPro Calibration Management software allows you to track the status of recurrent items such as calibrations, maintenance, validations, and reminders.
The first step on the road to knowing that parts coming off the machine meet specifications is ensuring in advance that the machine itself is capable of the desired accuracy.
Let's take a closer look at the practical side of Optical Tooling. We'll go over some examples of Optical Tooling principles at work and what you can do with the instrumentation.
The abbreviation CNC stands for computer numerical control, and refers specifically to a computer "controller" that reads G-code instructions and drives a machine tool
Milling is the process of machining flat, curved, or irregular surfaces by feeding the workpiece against a rotating cutter containing a number of cutting edges.
The lathe is a machine tool used principally for shaping pieces of metal (or other materials) by causing the workpiece to be held and rotated by the lathe while a tool bit is advanced into the work causing the cutting action.
A milling machine is a machine tool used for the complex shaping of metal and other solid materials. Its basic form is that of a rotating cutter or endmill which rotates about the spindle axis (similar to a drill), and a movable table to which the workpiece is affixed.
A Review of Basic Lubrication Concepts - Friction - Types of Lubrication - What every Lubricant Must Do - Components of a Lubricant - The Evolution of Synthetic Oils.
Motor Oil From Wikipedia, the free encyclopedia. While the main function is to lubricate moving parts, motor oil also cleans, inhibits corrosion, and cools the engine by carrying heat away from the moving parts.
Unlike changing the oil in your car based upon time or miles, oil changes for industrial equipment should be based on need where no other practical solution to restore proper lubrication is available.
Functions of engine oil stable oil film between sliding surfaces reliable engine operation in a wide temperature range Rust (corrosion) protection Cleaning the engine parts Sealing piston ring Prevention of foaming Cooling the engine parts
Lubricants, Oils, Maintenance. Don't Just Measure Performance … Manage It. Particle contamination control has several components, but it begins with good lubricant storage, handling and application methods.
Properties of gear oils; Proper viscosity; Ability to withstand extreme pressures (EP); Thermal and oxidation stability; Corrosion and rust protection; Compatibility with seal materials.
Bearings are among the most important components in the vast majority of machines and exacting demands are made upon their carrying capacity and reliability.
When a bearing in a critical piece of equipment fails prematurely, a maintenance specialist knows the failure usually indicates there is more here than meets the eye.
The software includes the very informative "Complete Guide to Learning CAD" by Randall Newton and Robert Berry (271 pages), the useful crossover guide "TurboCAD for Users" (144 pages) and a full multimedia Quick Tour
