Cnc Windows Software

CNC Windows Software
The development of​ computer numeric controlled (CNC) routing,​ using affordable personal computers has already begu​n 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.
