Intercon (offline) G84 tapping?

Post by frijoli »

When I set-up tapping in Intercon it stops on this line of code with no messages as to what is happening.

What am I missing?

Is the spindle running? (it looks like it's running CCW. Depending on your M29, it may be waiting for the spindle to run CW. For rigid tapping, Z axis movement is slaved to spindle encoder.. From the manual:

Parameter 36 - Rigid Tapping Enable/Disable (check in both offline and control)
This parameter is a bit field that enables or disables Rigid Tapping and its options.
Bit Function Description Parameter Value
0 Enable Rigid Tapping? Yes = 1, No = 0
1 Suppress sending "Wait for Index Pulse" during Rigid
Tapping?
Yes = 2, No = 0
2 Allow Spindle Override during Rigid Tapping? Yes = 4, No = 0
3 Use Spindle Off system variable bit?
(see note below)
Yes = 8, No = 0



M29- Set Tap Mode for G84
M29 sets the tap mode for G84; either right-hand or left-hand tapping. Right-hand tap mode is the initial default at
job start-up. If Left-hand tap mode is required, M29 and P1 need to be specified on the same line.
Tap Mode Command
CW ( Right-hand ) M29
CCW ( Left-hand ) M29 P1


G84 – Tap/Counter Tap
G84 performs both right-hand (Tap) and left-hand (Counter Tap) cycles. The tap direction, spindle speed, spindle
direction, feedrate and/or thread pitch should be set before the G84 is invoked. The tapping direction is set by
calling M29 with or without a P1 parameter (see M29 in Chapter 12). G84 defaults to right-hand Tap cycle if M29
P1 is not specified beforehand. The spindle should be started beforehand using M3 (Spindle CW) for the Tap
cycle, or using M4 (Spindle CCW) for the Counter Tap cycle.

For a floating tap head, the combination of the modal feedrate and spindle speed implicitly determines the
approximate thread lead or pitch. However, if Rigid Tapping is enabled, a Q may be used to explicitly set the
thread lead or pitch. However, because Q is not modal in the case of Rigid Tapping, you must specify Q on every
line at which Rigid Tapping is to occur.
The Tap/Counter Tap cycle might to cut a short distance beyond the programmed Z height as the spindle comes to a
stop before reversing. When tapping blind holes, be sure to specify a Z height slightly above the bottom of the hole
to prevent the tool from reaching bottom before the spindle stops. The exact distance you must allow will depend
on your machine and the diameter and pitch of the tapping tool.
WARNING FEED HOLD is temporarily disabled during the tapping cycle, but it will be reenabled
at the end of the cycle.
NOTICE Pressing CYCLE CANCEL while the tap is in the hole will very probably break the tap
or strip the threads in the tap hole. However, do so if it is an emergency.

How do you make the spindle run when using Intercon offline?
This code was programmed through the DEMO program. Rigid tapping bit is on.
Where is the M29 supposed to be added when using ICN CAM?

Thanks for the quick response.

You can't make the spindle run in offline. I thought you meant you were generating your g code in offline but running on control.

Okay, thanks Scott.
So, no way to dry run offline for rigid tapping and threading correct?
