Takes an address for dwell period (may be X, U, or P). The dwell period is specified by a control parameter, typically set to milliseconds. Instead, they require four quarter-circle arcs programmed back-to-back.) (Some older controls do not support this because arcs cannot cross between quadrants of the cartesian system.

Full circles: When the arc start point and the arc end point are identical, the tool cuts a 360° arc (a full circle). Often, a short linear lead-in movement is programmed, merely to allow cutter compensation before the main action, the circle-cutting, begins. You must already have compensated in an earlier G01 block. Cutter comp: On most controls you cannot start G41 or G42 in G02 or G03 modes. Addresses for radius or arc center: G02 and G03 take either an R address (for the radius desired on the part) or IJK addresses (for the component vectors that define the vector from the arc start point to the arc center point). In fact, the interpolation is so precise (when all conditions are correct) that milling an interpolated circle can obviate operations such as drilling, and often even fine boring. As with G01, the actual toolpath of the machining takes place with the given feedrate on a path that accurately matches the ideal (in G02's case, a circle) to within very small limits. In the case of G02, the interpolation generates a circle rather than a line.

This process repeated thousands of times per minute generates the desired toolpath. Again, the control interpolates intermediate points and commands the servo- or stepper motors to rotate the amount needed for the leadscrew to translate the motion to the correct tool tip positioning. Thus the actual toolpath of the machining takes place with the given feedrate on a path that is accurately linear to within very small limits. The computer performs thousands of calculations per second, and the motors react quickly to each input. The control then calculates the angular velocities at which to turn the axis leadscrews via their servomotors or stepper motors. The program specs the start and end points, and the control automatically calculates (interpolates) the intermediate points to pass through that yield a straight line (hence "linear").

The most common workhorse code for feeding during a cut. Some machines offer interpolated rapids as a feature for ease of programming (safe to assume a straight line). This matters because it may yield a dog-leg or hockey-stick motion, which the programmer needs to consider, depending on what obstacles are nearby, to avoid a crash. Shorter vector usually finishes first (given similar axis speeds). It moves each axis at its max speed until its vector quantity is achieved. Programs for any machine and control can be prepared, simulated and verified even in the absence of the real machine.On 2- or 3-axis moves, G00 (unlike G01) traditionally does not necessarily move in a single straight line between start point and end point.

You can do all the tests you want, quickly, without risk and without taking the real machine out of production.īecause it allows you to avoid the risks of damaging expensive workpieces, tools breaking and collisions with machine parts such as the spindle, caused by programming errors.Įureka g-code is also useful for training new staff and allows you to work remotely. Why Eureka G-Code?īecause it allows you to have a digital replica on your computer of the machines you have in the workshop. Thanks to 20 years of experience and development, Eureka G-code is able to emulate all the most popular CNC controls on the market: Fanuc, Siemens, Heidenhain, Haas, Fagor, Okuma, MoriSeiki, Mazak, Fidia, Selca, Osai, Num and many others. Eureka simulates the actual G-Code sent to the machine, regardless of how it was created, manually, or post processed from any CAM system.
