- This manual does not include the whole functionality of the control software FANUC SERIES 0-TC Turning, however emphasis was laid on the simple and clear illustration of the most important functions so as to achieve a most comprehensive learning success. In case any questions or proposals for improving this manual should arise.

- FANUC CNC GUIDE simulates CNC operator environments for programming and operation and includes the FANUC MANUAL GUIDE i. It runs on standard PC equipment with no need for additional hardware. We offer now the FANUC CNC GUIDE as a fully functioning test version until end of September 2020. Read about CNC GUIDE Download the CNC GUIDE.
Users must also observe the safety precautions related to the machine, as described in the relevant manual supplied by the machine tool builder. Before checking the operation of the machine, take time to become familiar with the manuals provided by the machine tool builder and FANUC. Free vmware esxi 5.1 license key crack.
Is Manual Machining Faster than CNC for Simple Parts?
CNCCookbook’s G-Code Tutorial
G-Code Tool Changes
Most CNC g-code programs will have one or more g-code tool changes programmed into them. This will be true even if your machine doesn’t have an automatic tool changer. That’s because the tool change programming serves two purposes. First, in the case of a machine with an automatic tool changer (ATC), the tool changing g-codes tell the ATC to load a particular tool in the spindle or, in the case of a lathe, to rotate that tool into position on the lathe’s turret. The second role of these codes is to set up a different tool length offset. The tool length offset tells the CNC machine how much the length of the current tool differs from tool #1. It will adjust its notion of where the tool tip is when you make your next move based on this.
Accomplishing these two functions can require anywhere from one to several g-codes. Let’s go through each possible g-code and it’s style of use.
T Tool Select and M06 Tool Change
The “T” word is commonly used to select a tool. On a VMC with ATC, usually the “T” word tells the mill to select that tool, but it requires the M06 word to be executed before the tool is actually changed. This gives the ATC a little bit of advanced warning, allowing it to rotate the new tool into position while the machine is busy doing something else, which can make for a faster tool change. On most lathes, and even for some mills, the M06 is not needed. On those machines, it is likely an error to use an M06.
Sample tool change using T + M06
N10 T12 ( Select Tool #12 )
N20 M06 ( Change to selected tool )
If the machine doesn’t use M06, the sample would look like this:
N10 T12
If you wanted to take advantage of the separate T and M06 to give your machine maximum time to get ready in order to make the tool change faster, you’d do something like this:
T12
M06
T14
(Machining with T12 in spindle, but T14 is ready for next M06)
M06
(Now T14 is loaded)
T02 (Setting up T02 for later)
(Machining with T14)
M06
(Now T02 is in spindle)

Random Memory Tool Selection
One trick some machines use to make tool changes go even faster is to set it up so tools don’t have to go back into a particular pocket on the changer. Instead, the machine just sticks the tool in the nearest pocket so it doesn’t have to take so long to rotate a pocket into position. The machine keeps track of which slot T02 is actually in, for example, and you can always refer to it as “T02”

Tool Offsets: Geometry and Wear Offsets
![Fanuc Fanuc](https://i.ebayimg.com/images/g/lx8AAOSwm-Zaujb3/s-l300.jpg)
Now what about that business of selecting a Tool Offset so the machine knows how long the tool is?
First thing to note is that there are actually 2 different length offsets–the Geometry Offset and the Wear Offset. The Geometry offset is associated with each tool by number and is the one that grossly determines tool length. The Wear Offset is a fine tuning change to the overall tool length that is used to compensate for wear and to give the machinist the ability to fine tune what’s happening from part to part. For example, you may be turning a part to diameter and discover that after measuring the diameter with a micrometer it is slightly off. Perhaps it is 0.0013″ too large. To correct, you can enter a wear offset of -0.0013 to cause the machine to come out much closer to the desired tolerance.
Let’s ignore the Wear Offset for the moment. When you do your tool change, your machine controller will automatically apply the Geometry Offset based on the information contained in its tool table about each tool.
Fanuc-Style Combined Tool Number and Offset for Turning
Now that we know about these offsets, let’s take a look at specifying a toolchange on a lathe using Fanuc’s syntax. It’s pretty simple. To select tool #2, we’d use:
T0202
“Why is the “02” repeated twice?” you wonder. That second “02” can be any 2-digits, and it selects the wear offset to use. By convention, most programs make the wear offset the same as the tool number so you don’t have to worry about matching them up.

You have the ability to specify the range of T#’s as well as how many digits at the end of the T# are used to specify the offset.
