Mike Lynch1 minTapping on a turning center (without canned cycles) Unless your Fanuc controlled turning center came with live tooling, it’s likely that you don’t have canned cycles (G80-G89) like those you find on machining ...
Mike Lynch6 minCan you speed up your tool change time? Machining centers, of course, have automatic tool changing devices to automate the tool changing process. Current models boast very fast tool changing times ...
Mike Lynch6 minSetting Up User Defined G and M codes Parameters control countless things about the way your CNC machine tools behave. In each Parameter preference segment, we will expose parameters that have an...
Mike Lynch7 minOutputting Fixture Offset Settings Two special commands are used in custom macro B to send data out through the communications port (RS-232c port). One called BPRNT allows the output of alpha-...
Mike Lynch4 minProgram Offset Entries Whenever Possible As you know, certain offsets must be entered before a job can be run. For machining centers, these offsets include fixture offsets, tool length compensation ...
Mike Lynch2 minThe safe approach procedure As you know, CNC machines have extremely fast motion rates. When you're verifying a program (new or proven programs), you also know that each tool will rapid...
Mike Lynch2 minHow do you enter the parameter setting mode? In past issues of The Optional Stop Newsletter, we've discussed several times when you might want to check the current setting of a given parameter to determ...
Mike Lynch2 minThe varied uses for M99 M99 can be used for several purposes. Here are the ones we know of: As an end of sub-program command The is the most common application for M99. As you proba...
Mike Lynch2 minUsing G53 - machine coordinate system You know that G90 specifies the absolute mode. Any coordinates specified after G90 will use the program zero point as the origin for the motion. This is the ...
Mike Lynch4 minUsing the machine's current absolute position in a custom macro One of the application categories for custom macro is user created canned cycles. In this category, you're creating your own canned cycle. As you know, most ...
Mike Lynch1 minWhich fixture offset should I use? This is a question that recently appeared in the CNC Tech Talk forum on our website. As you know, Fanuc controlled CNC machining centers use fixture offsets ...
Mike Lynch4 minSome special feature of G76 (the threading command) Fanuc's threading command is pretty powerful - and very helpful. It will allow you to completely machine a thread with one command in your program, regardles...
Mike Lynch2 minRunning a special series of commands in a program There may be times when you need to have the machine execute a series of commands that are related to your program, but not necessarily part of the program. ...
Mike Lynch2 minUnderstand Your Turning Center's Chuck Clamping Direction Selection Almost all current-model CNC turning center that are equipped with three-jaw chucks have a way to select clamping direction. An inward (toward chuck center) ...
Mike Lynch3 minUnderstand spindle speed limiting on turning centers Today’s CNC turning centers allow very fast spindle speeds. It is not uncommon for a machine having an eight inch diameter hydraulic chuck to provide 6,000 r...
Mike Lynch2 minChanging initialized states When you power up a CNC machine tool, certain modes are initialized – that is – automatically selected. With many machines, for example, the machine will com...
Mike Lynch2 minActivating a custom macro from a T word This is necessary if you want to incorporate the techniques shown in the Macro Maven article of this newsletter. With custom macro B, you have the ability to...
Mike Lynch3 minRestarting after breaking a tap One of the most frustrating problems a CNC operator can have is breaking a tap in the middle of taping many holes. The broken tap, of course, must be removed...
Mike Lynch7 minThe most important thing a CNC operator must know Most companies expect a lot from their CNC operators. Common tasks include: Loading and unloading workpieces Activating and monitoring the CNC cycle Measurin...
