Fanuc Cnc Lathe Programs' title='Fanuc Cnc Lathe Programs' />Features Pros Have that Hobby CNC Controllers Dont. Hobby CNC Controllers have gotten to where theyre quite powerful. I recently saw an article on a single chip CNC controllerno need for a PC, just add a few outboard parts and it drives the stepper motors, provides an LCD screen UI, and quite a lot more. Amazing stuff, and its only going to keep getting better over time. Despite their newfound power, there are a number of features that Pro CNC Controls have that most Hobby CNC Controllers do not. Celebrated Cases Of Judge Dee Download Adobe. Here are 1. 0 of them 1. Better Macros and Subprograms Fanuc Macro B vs Mach. Linux. CNCThis is one of the biggest ones for me. The ability to program the g code in Pro machines is quite a ways ahead of the Hobby Controllers such as Mach 3 or Linux. CNC.  Whats specifically missing so far are branching structuresIF, GOTO, and WHILE loops. You can only do so much with variables and subprograms without branching. Branching is the ability for the g code to change what it will do based on outside inputs. More and Better Canned Cycles. This is another one that makes a big difference, particularly when programming lathes.

Rigid Tapping via Closed Loop to the Control. Theres a lot of Holy War diatribe about whether or not there is Closed Loop all the way back to the Control when discussing such things as Mach. Linux. CNC.  I prefer to look at what specific features the user gets from Closed Loop rather than worrying about the theoretical implications, so Im going to name a few here. First up is Rigid Tapping. Gcode also RS274, which has many variants, is the common name for the most widely used numerical control NC programming language. It is used mainly in computer. Over the past three decades, Intelitek has established itself as the leader in affordable CNC Computer Numeric Control machines, with over 13,000 CNC machines. Lathe Head stock or spindle Alignment. Check spindle alignment by chucking up a piece of material and performing a cut. The material should be a minimum diameter of 2. Can Android Os Be Installed On Iphone on this page.

In theory it should be pretty straightforward to get this into Hobby Controls given that they support an encoder for threading on lathes, but you dont see it very often. Its not easy to do it right for one thing. The acid test is rapid tapping into a blind hole. How To Program A Motorola Xts 1500 here. If theres a mistake you either get too little of the hole threaded or the tap hits the bottom and usually breaks. Its an unforgiving application. Increased Homing Accuracy via Closed Loop. G76-Thread-Cycle-a-CNC-Programming-Example.jpg' alt='Fanuc Cnc Lathe Programs' title='Fanuc Cnc Lathe Programs' />Another neat trick the Pros use is to tremendously increase the accuracy of Home Switches by tying them to the Encoders on each axis. The actual Home Switch only has to identify the neighborhood within 1 encoder revolution. The precise position can then be read from the encoder position to an accuracy thats much higher than can be achieved with a simple Home Switch. Advanced Acceleration and Shape Control. Acceleration is always a bit of a bugaboo for CNC machines. They cant accelerate to the commanded feedrate instantly nor stop on a dime.

We added some information to our G Wizard Editor that tries to tell you what acceleration is doing to g code program run times as well as whats happening line by line. Thats extremely useful for cost estimating and for tuning up g code part programs to run better. The very best Controllers are all over the acceleration problem. They not only understand the acceleration capabilities of the machine, they also understand the actual shape of the acceleration curve. This can lead to a number of advantages including greater precision, smootherfaster speed changes, better surface finishes, and ultimately, shorter cycle times. They user this information together with Closed Loop Information and Lookahead Information about what the g code will do next to try to anticipate and stay ahead of the game. They can provide capabilities like Automatic Corner Override, Advanced Contour Control, Advanced Feed Forward Control, and Advanced Acceleration Control. If youre doing 3. D profiling or running a fancy HSM toolpath you will love having these features available from your Controller. Machine Compensation. No mechanical device is perfect. No ballscrew is without at least some small amount of backlash, nor does every inch of the ballscrew thread advance with perfect precision. Sometimes a commanded move of an inch is 0. With the right software in your Controller, it can try to compensate for these issues. Theres Backlash and Pitch compensation for the aforementioned ballscrew problems. Add to that straightness compensation which adjusts for the fact that the axes of the machine are not completely orthogonal to one another. As you move a machine in X, it may change Y or Z some tiny amount. Another important source of error is addressed by Temperature Compensation. As your machine warms up, parts expand at different rates. On a hot day it may be one thing and then you fire it up in the winter before warm up and it is quite another. Good controls can compensate for all of these things using a variety of techniques. They are calibrated periodically by a Ballbar or Laser Interferometer test to reset the compensation settings. Really fancy machines may even have glass scales similar to DRO scales that are continuously reading how much each axis actually moved and using that to update the Controller on whats really going on. Some of this is available for Hobby Controllersbacklash compensation and leadscrew pitch compensation are the ones I am familiar with. But its done in a far simpler manner and Hobby Machines seldom get the precise calibration to dial in compensation that Pro machines do. Advanced Tool and Part Program Management. Pro CNC Machines are often used for long part runs, so they have features to help manage Tools and Part Programs that are geared to that application. Theyll keep up with how long each tool in the changer has been in use, for example. On the part program side they can track program usage, verify version data, and organize programs in folders with extended descriptors. Really fancy controls can provide some front end menus for the operator that help make their job easier and give them options. For example, it is often convenient to be able to skip some parts of the program, for example when reworking parts that already have those features machined and just need to do the later work. Tool Compensation. I like to think of Tool Compensation as the Poor Mans CAM, but it is so much more. Tool compensation is essentially the ability to program g code for the tool centerline instead of the tools edge. The control will move the tool over by the right amount for the cut. When we specify our programs in this way, it is easier to write programs by hand, hence the Poor Mans CAM nickname. But it also unlocks a lot of power for the Shop Floor to make changes using wear offsets without having to change the part programs g code. Suppose you run a part and inspect it. Some of the features are out of tolerance a little bit. Compensating for that without tool compensation likely means youre going to have to adjust it at the CADCAM levela complicated and slow process. But, if your part program uses Tool Compensation, you can simply dial in another wear offset and suddenly your part is right on. Professionals constantly use this capability to increase the precision of their parts and to make minor adjustments where it just wouldnt be worth it to go back through a CADCAM cycle. Wait a minute, youre sayingHobby Controllers have this feature. Yes, sort of, but there are so many reports of bugs in the feature that I dont know of very many Hobby CNCers that are successfuly using the feature very often.
