It offers the most flexibility and the greatest potential power of any of the G-Code Programming Techniques.
Not all controllers support full Macro B, and there are variations supported by some non-Fanuc controllers. Until now, all of our g-coding has been done without any recourse to variables or formulas. If we wanted to go to a particular coordinate, we had to enter that coordinate, either absolute or relative, to get there.
A tremendous amount can be accomplished in that way, but just as algebra is more powerful than arithmetic, so parameterized programming is more powerful than basic g-code, and for the same reasons. Once you have variables, you can start to parameterize your programming.
Imagine being able to create your own custom canned cycles that can do almost anything. A custom drilling cycle, or perhaps a routine to automatically serial number your parts. Almost anything is possible. Covering the whole of parameterized programming will involve three chapters in our tutorial. The next chapter will delve into how to divide your code up into subprograms and access the subprograms.
Not all controls support parameterized programming. You may have noticed that different companies often make the CNC Controller versus the actual machine tool. In fact, this is nearly always the case. There are a collection of settings inside the controller that are called parameters that are used to perform that configuration of the controller to the machine tool. For example, the travels, spindle speed range, rapid traverse rate, and many other types of information that are critical to making the control work right with the machine.
You should make sure you have a good backup of all your parameters in case the battery fails on the controller or they get inadvertently changed.
Typically there is a procedure available for your controller to use DNC to perform a backup. First thing is first, what are variables? Simply put, they are just like algebra variables that you can use in your g-code. They can be assigned values, and when you refer to them, they give back the last value they were assigned. The syntax for a variable is the pound sign followed by a number up to however many digits your controller supports that identifies the variable. The variable 0 always has a null value, and you can give any other variable a null value just by assigning 0 to it.
These variables fall into ranges that affect their meaning and how they can be used. Here is how Fanuc thinks of these ranges, for example:. Fanuc Macro Variables: Note that these ranges may vary across controllers and especially for non-Fanuc controllers!
Mach3 has 10, variables available, from 0 to Use variables whenever you think you might want to change a value in different situations.
For example, suppose you have a macro or subprogram that cuts a square pocket. You probably want to have variables that let you define the size of the square and the feeds and speeds so they may vary as the material changes. Depending on the subprogram, you might want a variable for the top left corner of the square, or you might simply let that corner be the current position when the routine is called.
You may want a variable defining the depth of the square pocket. And lastly, you may want a variable that defines the diameter of the tool. System Variables and Local Variables have some special behaviors, so steer clear of those unless you specifically want those behaviors.Here are G-codes for Fanuc cnc control which are necessary for a cnc machinists to learn to understand cnc programming.

All rights reserved.A complete cnc part-program which shows how G98 and G99 canned cycle return level work with G81 drilling cycle and G83 peck drilling cycle for drilling of a component which have different heights.
G98 and G99 are modal commands that change the way canned cycles G81,G83 etc. When G98 is active, the Z-axis will return to the start position initial plane when it completes an single operation.
When G99 is active, the Z-axis will be returned to the R point plane when the canned cycle completes a single hole. Then the machine will go to the next hole. N Next drilling position Y10 as G99 is a modal g-code drill will keep on retracting to R-plane until G98 is given.

Fanuc G94 facing cycle is very simple to program and use. G94 G code parameters are explained below. N60 : G94 is a modal G code. It means G90 turning cycle remains active until another motion command is given like G00, G01 etc. But as you can see the cnc program block N60 only show the value for z-axis, so it means that the G94 facing cycle will continue to work and now G94 facing cycle will make the second facing cut, whose x-axis value will remain the same but the z-axis value will now be N90 : this cnc program block show a contradictory G-code for G94 which is G00, so this mean that the Fanuc G94 facing cycle has been ended.

All rights reserved.Ultimately, I use my own analysis in combination with intelligent based software. Wazzu's defense has steadily gotten worse as the season goes along. They allowed 91 to Idaho on the road and 81 to UC Davis as well.
Robert Franks and Malachi Flynn are averaging over 36 points per game combined. UTEP is feeling good after a 88-76 home win over New Mexico last time out. They will be once again without Matt Wilms in the middle. That will make the Miners defense much worse considering he's their enforcer type. Extra pressure now on Keith Frazier and Omega Harris. UTEP has gone over in 14 of their last 21 games when the total is 140 to 149. This game features the 13-11 Sixers and the 18-8 Cavs.
This game will be easy pickings as the Sixers will rest their star Joel Embid and this line just is too low. Cavs lost outrite last night at the Pacers and will not be to happy going into this one. In the last nine years, this situation is sensational 23-3.
The 7-5 Baltimore Ravens are in Pittsburgh to take on the 10-2 Steelers and for a number of different reasons, I think this on favors the visitors. Baltimore has won three straight. Pittsburgh enters off a come-from-behind 23-20 win over Cincinnati on Monday night. Note that this is a revenge game for the Ravens after they fell 26-9 to the Steelers in the first meeting back on October 1st. Denver, which has lost eight in a row after a 3-1 start enters into this game in a shambles.
HC Vance Joseph's first year as head coach hasn't gone as planned, and the entire team looks to be on the verge of mutiny. Meanwhile, the Jets behind veteran quarterback Josh McCown are doing well in what was supposed to be a rebuilding season. The experienced QB has 18 touchdown passes and only eight interceptions while playing every snap this season. Of the Jets' seven losses the jets have suffered during this campaign, only one has been by double digits, and they've had a fourth-quarter lead in three others and are a very under rated squad.
I'm betting the NFL offensive player of the week (McCown) and a cohesive blue collar group will once again be the catalyst behind a Jets victory here today. DENVER is 0-8 ATS in all games where the total is between 35. The Washington Redskins will visit the L.
Chargers at StubHub Center Sunday afternoon, and I think we'll see a high-scoring affair. The Redskins took a 38-14 loss at Dallas last Thursday and need a win here to keep their almost non-existent playoff hopes alive. Over is 14-3 in Redskins last 17 games following a straight up loss and 6-1 in their last seven games in December.
I expect a big game for rookie running back Samaje Perine against one of the worst run defenses in the league. The Chargers have allowed just a total of 16 points through their last two games, but first they played a Cowboys team still adjusting to the loss of Zeke Elliot and most recently the Browns.
