The program communicates with all existing models of Mazak dialogue controls using a standard RS-232C serial port or by using a USB to Serial to adapter on your computer.Several machines can be connected to one computer with different presets.I prefer to use C or R rather than I and K, so thats what I will explain here.
Mazatrol Program Samples Serial Port OrRather than add the Y-axis, a 3-axis lathe typically has X, Z, and C axes. In essence, it allows you to clock the spindle to specific angles. A three axis lathe with live toolign can do fairly arbitrary milling jobs on the part in the lathe chuck. We wont spend any more time talking about C-axis programming in this section because its beyond the scope of a simple introduction to CNC turning. In diameter mode, X-axis values specify diameters, while in radius mode, they specify a radius from the axis. You can set whether GW Editor defaults to radius or diameter in the post too. The difference is you can mostly ignore the Y coordinate (though there are lathes that have Y too). Just leave it out of the programs, and dont use the corresponding incremental J or V either. If your lathe has sophisticated canned cycles like G71 Rough Turning, this can be particularly easy, but even programming by hand isnt too bad. The X-axis zero is always chosen to be the spindle center line when turning for all sorts of reasons. But, the part is rarely against the chuck face, so this method introduces more complications in locating positions on the actual part. The disadvantage is that when machining starts, there is no finished part to touch off. Machinists typically use an allowance, or make a quick facing cut to create the finished end to get past that problem. First, the lathe uses no M06 commandthe tool is changed as soon as the T word is executed. Second, many lathes encode a tool wear offset into the address following the T word. Different controls may be set up with differing numbers of digits to select the tool and wear offset. This is done because turning work often needs to be to very tight tolerances, and the same tool is often used for multiple features on the part. By using a different wear offset for each feature, the machinist can measure the parts as they come off and tweak the wear offset so each feature is to the specified tolerances. Its beyond the scope of this intro chapter, but gang tooling will be covered in a later article. Suffice to say that with gang tooling, the tools are mounted on the slide and the program selects the tool by explicitly programming slide motions on the X and Z axes. Many controls provide a feature for just that purpose called automatic chamfer and automatic corner rounding. Mazatrol Program Samples How To Set ItOnce you get used to it, its a very handy feature to have, but it takes a little getting used to how to set it up.
