CAD meet CNC

CAD meets CNC
CAD CNC example.
     While the Servomechanisms Lab was in the process of developing their first mill, in 1953, MIT's Mechanical Engineering Department dropped the requirement that undergraduates take courses in drawing. The instructors formerly teaching these programs were merged into the Design Division, where an informal discussion of computerized design started. Meanwhile the Electronic Systems Laboratory, the newly rechristened Servomechanisms Laboratory, had been discussing whether or not design would ever start with paper diagrams in the future.[13]

      In January 1959, an informal meeting was held involving individuals from both the Electronic Systems Laboratory and the Mechanical Engineering Department's Design Division. Formal meetings followed in April and May, which resulted in the "Computer-Aided Design Project". In December 1959, the Air Force issued a one year contract to ESL for $223,000 to fund the project, including $20,800 earmarked for 104 hours of computer time at $200 per hour.[14] This proved to be far too little for the ambitious program they had in mind, although their engineering calculation system, AED, was released in March 1965.

      In 1959, General Motors started an experimental project to digitize, store and print the many design sketches being generated in the various GM design departments. When the basic concept demonstrated that it could work, they started the DAC-1 project with IBM to develop a production version. One part of the DAC project was the direct conversion of paper diagrams into 3D models, which were then converted into APT commands and cut on milling machines. In November 1963 a design for the lid of a trunk moved from 2D paper sketch to 3D clay prototype for the first time.[15] With the exception of the initial sketch, the design-to-production loop had been closed.

Meanwhile, MIT's offsite Lincoln Labs was building computers to test new transistorized designs. The ultimate goal was essentially a transistorized Whirlwind known as TX-2, but in order to test various circuit designs a smaller version known as TX-0 was built first. When construction of TX-2 started, time in TX-0 freed up and this led to a number of experiments involving interactive input and use of the machine's CRT display for graphics. Further development of these concepts led to Ivan Sutherland's groundbreaking Sketchpad program on the TX-2.

     Sutherland moved to the University of Utah after his Sketchpad work, but it inspired other MIT graduates to attempt the first true CAD system. It was Electronic Drafting Machine (EDM), sold to Control Data and known as "Digigraphics", which Lockheed used to build production parts for the C-5 Galaxy, the first example of an end-to-end CAD/CNC production system.

CNC Kits

  Construction of a CNC machine means that require a lot of tools, parts or other components. Many are built using CNC kits. These are many types of components that must be put together to build a CNC machine.

When building a CNC machine you need to make a decision whether to use a facility or a servo stepper motor. Now, this is one of the most questionable CNC. It tends to get quite confused on what to use and when to use and why we are going as they should. The fact is that each type of engine is able to provide several advantages over the other. It really depends on applications.

We require the following to build a CNC machine. All components listed below are usually contained in CNC kits readily available on the market.

a) printed circuit board (industrial grade) 
b) Drilled solder mask and serigraphy 
c) the high-end electronics 
d) supports hex
e) the son of the cable are connected in parallel to the computer
f) Connectors to build extension cables for motors
g) Same as stepper motors
h) for configuring the CNC software
i) Manual with step by step guide
j) 12V 4A
k) of the transformer, diodes, electrolytic capacitors to build your diet

  You can also take the help of a professional or someone who has already built some CNC machines like this.

5 Axis CNC

5 Axis CNC

 

CNC 5-axis refers to the ability of a Computerized Numerical Control (CNC) machine to perform 5-axis simultaneously. Most manufacturers describe their CNC machine movement from three axes: X, Y and Z. Z axis is parallel to the spindle. The other two axes are provided by the ability of the machine to rotate around the axis X and Y.

The Rx axis rotates around the axis parallel and X. Ry axis parallel to the wheel and around the Y axis Rz-axis represents the bottom bracket installed in the center of the cut of the machine spindle.

Using 5-axis offers some benefits. With such a machine, you can make complex shapes in a single set-up. In turn, this reduces the preparation time, which increases production rates. Moreover, with the elimination of different set-ups, time and errors are reduced.

The characteristic functions of accuracy is also improved with a 5-axis CNC machine because the same zero reference or data frame is used throughout the manufacturing process. Moreover, since the simultaneous rotation is allowed along the Y axis and X, the more rigid and shorter tools can be used.

The upper spindle / speed cutting tool can be achieved by reducing the load on the cut. The cutters shorter and often slow down the vibration when machining deep pockets or features molded with 3 axes.
Some applications of 5-axis machines include the complex three-dimensional profiles, which are common for the turbine blades, impellers, molds and plastic instruments. Using this tool, the activities which comprise only know information about the movement of tools such as forms processing, processing and cutting condition.

When you want to work on sculpture surface machining on 5-axis milling machines with numerical control, you must determine the direction vector of the cutter. The direction vector is obtained from the premise that the bottom edge of the racing milling free-form surfaces with a Z-Map method.

This Z-Map method can be applied to all types of surfaces carved geometric. After the 5-axis NC part programs are generated, the sculpted surfaces are machined with a 5-axis machine CNC milling.

3D CNC software is used for the graphic simulation and timing. With it, you can simulate and optimize the process already at work planning. There is no need to make complex tests on the real machine.

The errors in the program are immediately displayed on the monitor. In addition, the position of the suction cups is displayed and controlled to avoid collisions with tools when processing non-stop.

Among the highlights are moving the overall layout, the rotation of the workpiece after a CN-stop, and the simulation seen at different points of view. Although processing times are displayed without simulation. There are also automatic reading of the configuration of the machine with 3 axis and 5 axis CNC machining.

5-axis CNC machining is used to carve designs on wood to make furniture and interior design. It 'also used to cut out shapes of different materials as part of a finished product as do plastic helmets.

CNC Information

CNC Information - Data Storage and Transfer




A CNC machine must be considered when there is need to improve the speed and accuracy. The machine works better to do repetitive tasks and to achieve great works faster. Carpentry or industrial machine most likely from their collection of equipment. He made a purchase of quality that is never a problem for tomorrow. CNC valuable information can create the desire to have one.

By focusing on cost reduction and operational structure, but without taking into account the need to invest in better equipment, will not be the case. Some information may be CNC worth the time.

Despite the enormous needs, most people choose not to spend limited budget on a new model of CNC machines. Information with CNC, the purchase of equipment used or rebuilt at a new mid-price is affordable for individuals.

Controllers digital computer or computer-controlled machines are numbered obviously something to do with the controller. The machines are to perform their tasks by using the codes. The programs make their way through the mechanism of effective systems for data transfer. It 'must have sufficient knowledge about the data transfer methods and their effectiveness in transmitting data from one point to another.

A data set is represented by holes that are drilled into a long strip of paper. This method of transfer and storage of data known as punched tape has proven to be versatile and useful. The machine receives commands from the data set. Tells the machine how to move and what to do. If necessary, a punched tape can be visually decoded.

The magnetic storage device called a small disk has revolutionized the transfer and data storage. It allows space efficient and faster transfer of data. The disadvantage of its use is its tendency to deteriorate quickly.

About CNC include knowledge of how the set of interconnected computers called network makes it easier to share data. This allows remote access and data transfer among multiple users. More efficient registration and the balance of the system was created, since the program began the process easier and faster.

Orders can be placed directly into the memory of the CNC machines for manual data entry. Several drawbacks affect the efficiency of this method. The operation is very risky and time consuming. Furthermore, compared to the method of the construction of the network is not fast. Even in slow economic times, this information is a welcome relief CNC.

CNC Linear Motion Systems

CNC Linear Motion Systems

The linear motion system plays a vital role throughout the CNC milling machine CNC linear are no exception. Without these systems, coupled with a drive system, a CNC router would be of little use.

The Linear Motion Systems system is responsible for three main tasks.

1) Machine Components Support
2) Support secondary loads such as torque, lateral loads, etc.
3) Guide the machine in a precise linear motion with minimal friction (for ideal case should be without friction)


LM is a system composed of a certain type of linear bearings and linear guide bearings. There are a number of types of bearings and guides, each with advantages and disadvantages. Given the importance of this system is of vital importance for a buyer to know about a component manufacturer Linear Motion Systems Components.
