The development of computer numeric controlled (CNC) routing, using affordable personal computers has already begun to revolutionise all aspects of the woodworking industry. In so doing it has created new opportunities for large and small businesses as well as for individual craftsmen.

CNC is a technique whereby the movement of a router head is controlled by instructions from a computer. These instructions come from a computer program or list that the user keys into the CNC 860 console or into a computer as ISO standard commands called ‘G’ codes.As an example, the code G01 X100 Y100, instructs the head to move in a straight line to a point horizontally and vertically 100mm away from its starting position.

The CNC 860 The Trend CNC package is based around the Elu/DeWalt CNC 860 Machining Centre, which has a machining area of 860mm x 860mm x 90mm. These dimensions relate to the three axes, X,Y and Z (width, length and height). Each axis is served by a separate stepper motor, controlling the movement of the routing head. Two head options are offered: a modified portable router or a continuously rated, high cycle motor, that provides improved performance for intensive machining applications.

Programming directly in G-codes through the console can be time consuming. To assist the operator, a PC software application called CNCTalk is included with the machine. This is a basic computer aided design (CAD) application which runs under DOS, the original PC operating system before Windows. It is useful for intermediate applications like cutting out irregular shapes. However, to gain the maximum versatility from the CNC 860,Trend’s Open Sign System Software for Windows is the most effective solution.

OSS consists of two separate software applications: OSS Draw which provides the drawing tools to create any shape or sign, and OSS Work which handles all the routing and tooling-related parameters like depth and offset. Graphical simulations are shown for all tool parameters enabling the user to perfect a design before routing any material.

Sign-writing As an example of how these products work together, the method of producing a simple sign is shown, incorporating two different lettering styles and a graphical logo. Having launched OSS Draw, the first step is to draw a box or boarder on the screen to indicate the overall area of the work. This can be either a simple rectangular boarder or a more decorative one. This border then needs to have a depth assigned to it. This is done by using colours to define the depth of each area.

The logo is then created using the drawing tools within OSS Draw. The words are keyed in using the text function. Again, colours are assigned to each area to produce a graphical representation of how the finished sign will look. The next task is to define the routing parameters. In the example, the red and blue areas of the logo and the lettering have been assigned a depth of 5mm and the green area assigned a depth of zero. The same dialogue box lets you specify whether a letter or object is engraved or routed through the material. The cutter profile that will be used can now be defined. With lettering, particularly serifed fonts, the cutter used needs to have a small diameter, perhaps 3mm. However, to achieve a 5mm cutting depth this will have to be routed in several passes.

A simulation of the cutting path is now drawn on screen. Having then created a G-code file of the sign ready for the CNC 860 to cut, the file is downloaded to the CNC 860. The design can now be routed, the material being held on the bed by an adaptable clamping mechanism. From the simulation, the path that the tool will take is known allowing a datum point to be set using the zero key on the console, and the program 8 INProfile is run using the start key. This type of routing operation takes around 20 minutes to complete and requires no further involvement by the machine operator. Other accessories Sign-writing is just one of the many complex and wide ranging routing operations that can be carried out using the OSS and CNC 860 package. OSS also has a range of tools for drawing component shapes and profiles directly or with an electronic sketchpad (graphics tablet). Vacuum Clamping To reduce the through-put time for this kind of operation, the CNC 860 can also be used with a vacuum bed. Trend offer a complete range of affordable vacuum pumps and jigmaking accessories to enable all CNC users to produce a highly automated production system to suit their own specific requirements.

What Is Spyware Software And What Does It Do?

What Is Spyware Software And What Does It Do?

If you own a computer and are connected to the internet then you will almost definitely have heard of spyware software and will also be at risk. The purpose of this article is to inform readers as to the risks of spyware software and explain exactly what spyware is and what it does.

Spyware as the name suggests is software that spy’s on you and collects information on your internet usage. The computer user will be unaware that this is happening as spyware software applications are usually hidden components in both freeware and shareware programs that can be downloaded from the internet. Spyware is installed without your knowledge or consent and poses some very real threats.

Once spyware software has been installed onto your computer it will actively begin monitoring your activity on the internet and will transmit all the information it gathers onto its owner which is usually an advertiser of some sorts.

Spyware software is very dangerous and this illegal software can record your internet history, passwords, and keystrokes, and some spyware can also record other confidential and private information. The only proven and successful way to get rid of spyware is to install a spyware blocker or anti-spyware software. These are available in both free and paid software versions.

If you use the internet, for whatever use, you should also use a spyware blocker or spyware removal software. It is also essential that you run this spyware removal software daily to remove any threats to your personal information. Doing this will not only help to keep your internet usage and private information safe but it will also help to keep your computer running efficiently.

Spyware software is as mentioned very dangerous and allowing your personal information which can include passwords and bank details to get into the hands of the wrong people can prove detrimental. Act now and install anti-spyware software and keep your information safe.

Software

Computer software programs enable computers to perform specific tasks. It is removable and is differentiated from the physical components of the computer system which is called hardware. Application software allows a user to do something specific as in a word processing software program. System software allows the computer to run application software by interfacing with hardware and other software made to user specifications.

In computers, software is loaded into the random access memory (RAM) and is executed in the central processing unit (CPU). At its lowest level, software consists of machine language specific to an individual processor. Software is a sequence of instructions that changes to state of the computer’s hardware in a particular sequence so that the programs can run properly.

There are many different types of software. Of course, the system software is the operating system such as Windows or Linux. Application software can be in the form of games, applications, word processors, spreadsheet programs, and more. It is installed in the RAM and a point and click link is put onto the desktop to allow the user to launch the program easily.

Another type of software is programming software. This is a program that provides tools to a user allowing them to write computer programs in a computer language without having to know everything about that language. Programming software will include text editors, interpreters, link generators, and more. A good example of programming software would be Dreamweaver that allows a person to develop a web page without having a working knowledge of HTML.

A simple example of the way software operates can be illustrated by what happens when a user selects an entry such as “Copy” from a menu. In this case, a conditional instruction is executed to copy text from data in a document area residing in memory. If a different menu entry such as paste is chose, the software may execute the instructions to copy the text from the clipboard data area to a specific location in the same or another document in memory.

The only limitations on the use of computer software in applications lies in the ingenuity of the designer/programmer. Large areas of activities formerly assumed to be incapable of software simulation are now routinely programmed. The only area that has so far proven reasonably secure from software simulation is the realm of human art, but developments in this area are surely not far away.
