Series 0 i-MODEL F The FANUC Series 0 i-MODEL F is the newest generation in the highly popular Series 0 i and integrates many features found on the Series 30 i-MODEL B. The Series 0 i-F brings faster, more accurate performance to a wide range of milling, turning, punching and grinding applications with more standard features, more advanced capabilities and faster communications than ever before.
The Series 0 i control is the industry's most reliable system with a Mean Time Between Failure rate of 52 years. The Series 0 i-MODEL F offers more axes, ladders and paths, as well as high-speed auxiliary machine functions and an expanded list of standard features.
Additional features available on the Series 0 i-MODEL F include 15' display, QWERTY keyboard, I/O Link i, high-speed rigid tapping, function for loader control, tolerance control, axis name expansion, program folder management, quick program restart, flexible path axis assignment, multi-path PMC function, ladder dividing management, EtherNet/IP and PROFINET. Optimized Speed The Series 0 i-MODEL F features a suite of advanced motion control software functions to reduce cycle times while enhancing part accuracy and extending machine life. 32-Alphanumeric Character Program Names The Series 0 i-F now allows program names with up to 32 alphanumeric characters so it is compatible with Series 30 i-B. High-Response Vector Control High-Response Vector control (HRV 3) is a high-speed DSP, digital servo and spindle current-control method that provides greater precision and allows for higher machining speeds. Bell-Shaped Acc/Dec Bell-shaped acc/dec minimizes machine shock and reduces the time it takes to accelerate and decelerate and can be applied to rapid, contouring and tapping motions. AI Contour Control AI Contour Control (AICC I/AICC II) uses advanced look-ahead algorithms to determine the optimal feedrate and acceleration. This can reduce cycle times and improve accuracy, which is especially beneficial when machining complex, curved surfaces such as aerospace or automotive parts or metal dies. Tool Retract & Recover Tool retract and recover simplifies tool inspection and replacement while machining.
When activated, the tool safely retracts from the part and then can be manually moved to an inspection position. When released, the tool moves back along the path created by the manual moves. Path Synchronization M-codes are used to make one path wait for the other path to complete an operation before proceeding. One path can also be commanded to wait until another path reaches a specified absolute coordinate position before continuing. Twin Table Control Twin Table Control adds flexibility for twin-table machining centers and routers. The movement of each table can be synchronized to act as one large table, or managed independently for complex production runs.
Program Restart Program restart allows mid-program startup when the program was interrupted for a tool inspection or the machine stopped for a prolonged break.
G84 G Code: Programming Tapping Cycles in CNC Rigid Tapping, Tapping Heads, and Tension Compression Tap Holders Introduction: Tapping on CNC Machines G84 g code is commonly used to program tapping. Tapping is a common operation used to thread holes on CNC Machines. For more on the Feeds and Speeds as well as the different kinds of taps and tap holders, see our companion.
In this article, we’ll be looking at two ways of programming tapping on a CNC: – Tapping Cycles that can use the Rigid Tapping capabilities of your CNC Machine. – Long Form (no canned cycle is needed or used) programming when a Tapping Head or Tension-Compression Tap Holder is to be used on machines that do not have Rigid Tapping.
How to Program Rigid Tapping With a Canned Cycle To use Rigid Tapping, your machine must support the synchronization of feed motion with the spindle speed. This is typically an extra-cost option for CNC Machines and is harder to come by on older machines. The most common GCodes for Rigid Tapping Cycles are: – G84 G Code: Tapping of right hand threads to be done with M3 spindle rotation.
– G74 G Code: Tapping of left hand threads to be done with M4 spindle rotation. With some machines and controls, just simply using these cycles is sufficient for Rigid Tapping. On others, you must trigger a Rigid Tapping motion mode using another code. M29 is the common way to do this on Fanuc controls, for example. Let’s say we want to tap a 1/4-20 thread 0.500″ deep at 0, 0. Here’s the code to do that with G84 G Code: M03 M8 ( Speed and Feedrate ) S400 F20 ( Tapping ) Z1.0 G00 X0.0 Y0.0 G01 M29 G84 Z-0.5 R0.2 Let’s go through line by line: M03 to get the spindle moving in the right direction and M8 to turn coolant on.
Next we set spindle speed to 400 RPM and feedrate to 20. With this particular cycle, it expects feedrate in threads per inch (or mm in metric mode).
Next we move down to Save Z and XY. We switch to G01 and we use M29 to turn on Rigid Tapping. Lastly, we run the G84 with Z indicating the bottom of hole coordinate and R indicating the retract coordinate. If we had more holes to tap we could list their XY coordinates immediately following like this: G84 Z-0.5 R0.2 X0.0 Y1.0 X0.0 Y2.0 etc. G84 G Code is modal like most canned cycles.
When we’re done with it, we use G80 to cancel or simply switch to an alternate motion mode such as G00, G01, another canned cycle, or an arc. Pretty simple with a canned cycle, right? That code is straight from, which can generate the gcodes for such cycles very easily.
Here’s what the Wizard’s popup looks like with the settings for this example: Answer a few simple questions and G-Wizard Editor’s Conversational CNC will generate your tapping code for you How to Program Tapping on Machines that Lack Rigid Tapping If your machine can’t do Rigid Tapping, you’ll need to use a special tap holder. There are two common types described in our: a Tapping Head or a Tension-Compression Holder. There are pros and cons for each described in the other article. The purpose of the special holder is to allow some up/down motion of the tap in case the spindle speed isn’t precisely right for the feedrate. This lets the threading process itself regulate the true feedrate and it works well.
A tapping head has some other functions that enable it to tap faster too. Here’s a quick video of a tension compression tapping head: Programming these is fairly straightforward. Here is some basic code: M03 M8 ( Speed and Feedrate ) S400 F20 ( Tapping ) Z1.0 G00 X0.0 Y0.0 G01 Z-0.5 Z0.2 G00 Z1.0 Same sort of thing but in this case, it is done long-form with no tapping cycle. You could use one of the canned cycles to shorten the code, but it’s so simple to use the long-form, why not? There are some embellishments to the code that may be helpful depending on the equipment you’re using: 1.
A Tapping Head may have a gear ratio that allows it to retract faster. You’ll want to change the feedrate when retracting if yours does.
A Dwell at the bottom of the hole may be helpful as the spindle reverses to even out the amount of spring adjustment being used. For a lot of these devices, it can be helpful to drag the feedrate a bit. About 5% should do it. This is due to many of them performing better in tension than compression.
