Overview
TMAC uses a jobs-based system to store monitoring information. A job contains all parameters that TMAC needs to monitor tools for any operation in a machining task. A valid operation must include a tool, section, and channel(s). A job must contain at least one operation. For each operation in a job, limits and para- meters must be specified.
Each job is stored in the database. An unlimited number of jobs can be created. Tool numbers from 1-99999999 and section numbers from 1-99 can be specified for each operation. Once a job is created, it can be loaded at any time using the Job Operations Menu or by external command. The job-based structure is utilized specifically for Cutting Mode operations.
Note: Calls for the job and operations can be included in the part program. While in Learn mode, TMAC can utilize these calls to automatically create the job and populate it with the called operations.

Duplicating Operations
Selecting Duplicate from the Job Options menu allows the user to duplicate the tool or a section from the selected operation. Duplicating a tool creates a new tool and duplicates all sections associated with the selected tool. Every para- meter, feature and limit from the old operations are copied to the new operations with new tool and section numbers. Duplicating a section creates a new section associated with any tool and copies all parameters, features and limits from the selected section to the new section.
Note: Duplicated operations can not access the chart data used to create time increments from the old operation. For example if Tool 2 Section 1 was duplicated from Tool 1 Section 1, the time increment editor can not be opened for Tool 2 Section 1 as there is no chart data available for the new tool. If a tool already has time increments when it is duplicated, the time increments will be duplicated as well.

Features
The following sections document the features available in the Job Editor. As cer- tain features are enabled, the fields available in the Job Editor may change. These changes are documented specifically in the feature description. Some features that require more extensive documentation are documented in separate chapters of the manual. These features are as follows:
- Time Increment Editor
- Limits and Delays
- Adaptive Control
- Approach Override
Learn Once
The Learn Once feature permits TMAC to re-learn a specific operation. During the next execution of the part program, TMAC will enter learn mode for the designated operation. Once the operation is complete, TMAC updates the learn parameters and disables the Learn Once feature automatically.
Enabling Learn Once
In the Job Editor:
- Specify the operation by selecting the tool, section, and channel from the lists on the left side of the Job Editor. The selected operation is displayed at the top of the Job Editor.
- Activate the Learn Once feature by clicking its check-box. The Learn once check-box is located in the Learn Mode Options section of the Job Editor.
- Click SAVE.
Each time the operation is called while TMAC is in Learn mode, TMAC will switch to monitoring mode for the duration of the operation. After the operation is complete TMAC returns to learn mode.
Learn Disable
Learn Disable disables learn mode for the specified operation.
Utilizing Learn Disable
In the Job Editor:
- Specify the operation by selecting the tool, section, and channel from the lists on the left side of the Job Editor. The selected operation is displayed at the top of the Job Editor.
- Activate the Learn Disable feature by clicking its check-box. The Learn Disable check-box is located in the Learn Mode Options section of the Job Editor.
- Click SAVE
Each time the operation is called while TMAC is in Learn mode, TMAC will switch to monitoring mode for the duration of the operation. After the operation is complete TMAC returns to learn mode.
Dither
In some machine tool operations, tool chatter can occur from harmonic vibrations during the cut. Oscillating the spindle speed over a period of time disrupts the harmonics that causes tool chatter. Enabling the Dither feature allows TMAC to control and oscillate the spindle speed.
The dither settings are as follows:
- Mode: Designates one of two dither modes; Step and Ramp.
- Period: The amount of time in seconds to oscillate the spindle speed between the highest and lowest variation and back to the normal spindle speed.
- Delta: The oscillation percentage above and below spindle speed. For example, if the spindle runs at 1000 rpm and the delta percentage is set to 10%, the spindle speed will oscillate between 1100 rpm and 900 rpm over the time period.
- Note: TMAC does not need to be configured to monitor spindle speed to use the Dither feature.
Step Mode
When using Step Mode, the spindle speed is increased and decreased rapidly at certain time increments. When Dither Step mode is enabled and a start command is issued, the spindle speed immediately increases to the positive delta percentage for half of the programmed period. The spindle speed then drops to the negative delta percentage for the second half of the period.
Ramp Mode
When using Ramp Mode, the spindle starts at 100% speed and increases over time to the positive delta percentage programmed. It then decreases to the negative delta percentage, followed by an increase back to 100%.
Fixed Scale
TMAC utilizes a combination of learned values and programmed limits to automatically determine the scale for an operation. There may be instances where fix- ing the scale for an operation is more desirable. In those instances, it is helpful to set a fixed scale. Enabling Fixed Scale in the Job Editor unlocks the scale field found in the Learn parameters.
Setting a Fixed Scale
In the Job Editor:
- Specify the operation by selecting the tool, section, and channel from the lists on the left side of the Job Editor. The selected operation is displayed at the top of the Job Editor.
- Activate the Fixed Scale feature by clicking the check-box. The Fixed Scale check-box is located in the Features section of the Job Editor.
- Click the Scale field in the Learn Parameters section of the Job Editor and enter the desired scale
- Click SAVE
Monitor Hold
The Monitor hold feature disables monitoring for a specific operation. This is use- ful for temporarily disabling monitoring when fine-tuning the monitoring limits for a operation. During Monitor Hold, the TMAC process continues to monitor all other operations where Monitor Hold is not specified. Data for the specified operation is still collected for purposes of review, but the signal is not tested against the programmed limits.
Enable Monitor Hold
In the Job Editor:
- Specify the operation by selecting the tool, section, and channel from the lists on the left side of the Job Editor. The selected operation is displayed at the top of the Job Editor.
- Activate the Monitor Hold feature by clicking the check-box. The Monitor Hold check-box is located in the Features section of the Job Editor.
- Click SAVE.
When the part program is executed, TMAC enters a disabled state for the duration of the operation. Once the operation is complete, TMAC returns to monitor mode.
Idle Follows
The Idle Follows feature re-captures the idle value any time the motor value decreases below the previously captured idle. This can prevent TMAC from storing an incorrect idle when a machine is first started. Idle Follows is commonly used on machines with large spindles that tend to use more power to get up to speed. Using Idle Follows allows TMAC to recapture the idle value after the spike in power, thus properly monitoring the tool.
Note: Be sure to re-learn any operation where idle follows is specified.
Specifying Idle Follows
In the Job Editor:
- Specify the operation by selecting the channel, tool and Section from the lists on the left side of the Job Editor. The selected operation is displayed at the top of the Job Editor.
- Activate the Idle Follows feature by clicking the check-box. The Idle Follows check-box is located in the Features section of the Job Editor.
- Click SAVE.
Idle Reset
Idle Reset is a feature specific to time increments. If Idle Reset is specified for a time increment, TMAC automatically samples the monitored value at the instant the time increment begins. The system then uses that sampled value as the new idle value for all subsequent time increments unless Idle Reset is specified for a subsequent time increment.
Specifying Idle Reset
In the Job Editor:
- Specify the operation by selecting the tool, section, and channel from the lists on the left side of the Job Editor. The selected operation is displayed at the top of the Job Editor.
- Specify the time increment by selecting it from Time Increment Time-line. The selected time increment is displayed to the left of the time-line.
- Activate the Idle Reset feature by clicking the check-box. The Idle Reset check-box is located in the Features section of the Job Editor.
- Repeat steps 2 and 3 for any additional time increments, if necessary, then Click SAVE.
Filters
TMAC can utilize filters to reduce unwanted signal noise. TMAC has the following options for filters:
- Averaging Filter: Centers the signal at zero and averages the total magnitude of the signal. Typically used with vibration monitoring.
- Low Pass Filter: Passes low-frequency signals but reduces the amplitude of signals with frequencies higher than the cutoff frequency
- Filter Cuttoff Options: .075 Hz, 1.5 Hz, 3 Hz, 6 Hz, 12 Hz, 18 Hz, 24 Hz
Setting A Filter
In the Job Editor:
- Specify the operation by selecting the channel, tool and Section from the lists on the left side of the Job Editor. The selected operation is displayed at the top of the Job Editor.
- In the Filter Options section of the Job editor, select a filter mode from the drop down
- If selecting Averaging continue to step 3
- If selecting a low pass filter, select a cutoff frequency from the drop down menu
- Click SAVE
Start Delay
A Start Delay inhibits monitoring during a specified start delay period. There are many situations in which a start delay helps avoid an unnecessary alarm by delay- ing the capture of the idle value.
Note: All limits are inoperative while the start delay is in progress. No other delays begin until the start delay has timed out.
Setting a Start Delay
In the Job Editor:
- Specify the operation by selecting the tool, section, and channel from the lists on the left side of the Job Editor. The selected operation is displayed at the top of the Job Editor.
- Enter the desired delay in the Start Delay field. The Start Delay field is located in the Timing Section of the Job Editor.
- Click SAVE
Is Tap
If the control is configured to support this feature, a tapping operation can be specified. This feature permits a special case extreme alarm called a “tap alarm” to be issued when the programmed extreme limit is reached for that operation. A tap alarm causes the machine to reverse the tap out of the part before the machine is put into an interrupt or alarm state. How the tap alarm behaves is determined by alarm settings located in the Instance parameters. The settings are as follows:
- Tap Extreme Delay: Sets a delay between when the Tap Output turns off and when TMAC is put in extreme alarm that triggers a feed hold or interrupt.
- Output Off Delay: This setting determines how long the Tap Alarm Out-put stays on. This timer determines how long the machine has to finish reversing the tap out of the part before an alarm is triggered.
- Adaptive On Follows tap: This is an optional setting that turns on the adaptive output when the Tap output turns on. This parameter is for specific use cases.
Note: These settings are typically set by integrators and only available for specific machines.
