    Work co ordinate setup

    Hello rj, Yes, it's only redundant until you have a situation like the OP, where the Work Shift Offset is set to the default Offset when Reset is executed' For the sacrifice of the little memory consumed by including this information with every tool, it's made up many fold by the ease of being...

    Work co ordinate setup

    I suspect that you continue the program from the start of a Tool Operation, rather than in the middle of machining part of the Tool Operation. It could be unsafe to try and start the program part way through the cutting part of a tool operation, unless you know exactly what you're doing, for...

    Error RS232C_2

    As Kevin suggests, that's a band aid fix at best. Slow the baud rate down enough and the program can be sent successful with no handshaking whatsoever. As mentioned in my previous Post, buffer overflow is uncommon when transmitting a program to the memory of the control, if the RS232 protocol...

    G12.1 on a Mori Seki Wont do a Radius...

    With all due respect, based on the program you listed in your earlier Post, you either need to get a decent Post Processor for CAM System, or, if you're going to continue with manually creating programs using Polar Interpolation, learn how to calculate the correct start and finish coordinates...

    Error RS232C_2

    Buffer Overflow is rather uncommon when just transferring a program from an external device to the Control Memory, if settings at the Control and External Device are correct, particularly the Handshake method. Its far more common to experience Buffer Overflow when operating the machine via DNC...

    Error RS232C_2

    It's the reaction of the External device UART that can cause the Buffer Overflow at the control when Software Handshaking is being used. The DC characters are transmitted in the same way and baud rate as data characters and its the external device sending more than 10 characters of data after...

    Error RS232C_2

    There are two types of Handshake available, Software (Xon Xoff) and Hardware. Having the wrong Handshake Method set at the control, or external device, relative to the cable configuration will give rise to this error. Mismatched Baud Rate between the two devices will just give you rubbish data...

    Macro Programming Fundamentals

    Hello Moriseikiman, Most of your messages in the Message Blocks, contain more that 26 characters, including spaces, therefore, will be truncated to 26 characters when displayed. This may have the message not make much sense to the operator; accordingly, an abbreviated message is better than a...

    Tooling for a 1/2"-5 Acme double start internal thread 1.25" long

    Hello Marcus, Yes, I've had a brain fog moment. For some inexplicable reason I took the 10 and 5 as mm, rather than TPI. Accordingly, 5 TPI would be the Lead as SND stated and 10 the pitch. In the other example, 2.5 TPI the Lead and 5 the pitch. It's convention that with Multi Start Imperial...

    Tooling for a 1/2"-5 Acme double start internal thread 1.25" long

    For clarity for those reading that don't know much about multi start threads, you have your terms arse about. The Pitch of a Tread is obtained by dividing the Lead by the Number of Starts and conversely, the Lead by multiplying the Pitch by the Number of Starts. Therefore, in your first example...

    Okuma LB15 stuck chuck on spindle taper

    The method of using the Draw Tube to push the chuck loose normally works, but you need to screw the draw tube back to being fully engaged with the chuck; there will still be enough forward motion left to dislodge the chuck.Don't try using the hydraulic with the draw tube only engaged by a few...

    Help with a Lathe tapping cycle

    As suggested by Ox, but also delete G97 S85 M03, M29 S85 and the Tapping Cycle will start the spindle. It depends on the implementation of Rigid Tapping by the MTB as to whether starting the spindle prior to calling the rigid tapping will affect the operation, so having the spindle started from...

    Boring Head Pullout

    Hello Painkeeper, There are quite a few Canned Cycles for boring, but in particular for accurate bores, G85 cycle will will feed in to the specified Z coordinate and then feed back out to the "R" plane specified. G87 cycle will feed into the specified Z coordinate, the spindle will: 1. stop and...

    Cylindrical interpolation: Thumb rule to determine direction of G2/G3

    Hello Jaanyaar, Whether G18 or G19 is correct will depend on which axis the C axis has been set parallel to in parameters. If set parallel to the X axis, G18 will be correct. If set parallel to the Y axis, G19 will be used. Regards, Bill

    Cylindrical interpolation: Thumb rule to determine direction of G2/G3

    I'm not offering a testimonial, nor am I seeking your approval. I know what I know and the likes of Kevin, AKA Vancbiker, others and I, learnt NC and CNC programming when there were no teachers, or Forums; it was basically a matter of swimming or sink. Particularly when running your own...

    Cylindrical interpolation: Thumb rule to determine direction of G2/G3

    Absolutely. I have put up evidence that supports my own experience, and directed you to view articles in Fanuc Manuals, that clearly supports what I have Posted, but you still seem to doubt its validity. As I've pointed out in previous Posts, many other makes of controls have the CI features...

    Cylindrical interpolation: Thumb rule to determine direction of G2/G3

    He and you seem to think that the direction of G02/G03 are revered. I'm telling you that they are not, and I've provided ample proof that they're not. The whole concept of CI is that the cylindrical surface is programmed as if unwrapped, laid flat and programmed as you would an X/Y profile on a...

    Cylindrical interpolation: Thumb rule to determine direction of G2/G3

    Well, seeing as I've gone to great length to try and explain to you how CI works and that the direction of G02/G03 are in fact not reversed, perhaps you could be more specific and point it out.

    Cylindrical interpolation: Thumb rule to determine direction of G2/G3

    This sketch was more for explaining to those where I was installing a machine and conducting training, as to how to determine which actual axis the imaginary axis is parallel to, which is a requirement for setting a parameter associated with CI. The direction of rotation of the rotating axis was...
