ExactDress™ Wheel Dressprocess Control Card
Improve dressing efficiency and extend wheel life.
SBS ExactDress™ reduces dressing time and increases wheel
life for both profiled and standard grinding wheels. ExactDress uses
SBS AEMS proprietary acoustic sensor technology to monitor thehigh ­frequency signals generated on the grinding ­machine structureduring the dressing process. It compares the current AE process
signal of a wheel dress to a stored Reference waveform of a known
good dress to determine and report when the dressing process
has been successfully completed, maximizing the efficiency of the­dressing process.
Setup couldn’t be easier. Simply dress a wheel to teach the system
the AE Reference waveform of a successful dressing process. The­system maps the entire duration of the process and breaks it into
time slices or “zones,” indicated by a bar graph on screen. ­During
operation, the system displays which (if any) of the zones in thedressing process are not complete, and informs the CNC control
when the entire dress process has completed successfully.
ExactDress also includes gap and crash control. Initial contact ­between
the wheel and the dressing tool can be detected so the ­machine­control can stop wheel in-feed without operator inter­vention, reducing
cycle time. It can also detect and report an ­abnormal contact within
milliseconds, allowing the in-feed to be stopped, avoiding a crash,damage or injury.
ExactDress monitoring permits the operator or CNC control to(1) determine if the wheel is being dressed fully across its width,(2) control the aggressiveness of the process, and (3) maintain thequality of the dressed wheel while conserving process time andwheel material.

DETAILS
Measurement Parameters for Dressing Control
Zone Minimum:
This parameter specifies what percentage of the Reference Waveform must occur as a minimumat each zone of the process. During the teach process, the system divides the cycle automaticallyinto zones. Each zone corresponds to a time slice of the entire process. During monitoring eachzone of the current Process Signal is compared with the corresponding value of the Reference
Waveform. If the zone minimum value percentage of the Reference is not achieved for any zone,
the machine performs another dressing pass.

Clear visualization of the entire
timeline of the dress processprovides unique informationand insight.

On screen indication of relay
status shows if process is intolerance.

Maximum Minimum:
The parameter provides an adjustable upper signal level limit for the process, which serves as anindication that too much dressing contact has occured. If it is exceeded, the dress in-feed mayneed to be adjusted to reduce the aggressiveness of the process.
Ignore Level:
This parameter establishes a baseline signal level for all process zones. Any zone in the reference
waveform that has a signal valve below the Ignore Level will be automatically excluded fromanalysis. This allows for suppression of normal signal noise during process analysis.
Zone Edit:
The EDIT menu can be used to edit the saved Reference Waveform to turn off evaluation of theProcess Minimum status for any zone(s) within the process. This can allow any zones that represent a portion of the process that does not require process control to be ignored in the determination of process status. This can have benefits where a portion of the process does not produce
consistent AE signal levels and where this portion of the process is outside the area of concern formonitoring.

Available Outputs to CNC
Gap Detect:	Indicates the AE signal level has risen above backgroundlevels, showing that wheel contact has been initiated.
Crash Detect:	Indicates a wheel crash event has occurred within 2ms of thesignal detection.
Process Minimum:	Indicates if all zones of the current process have met theminimum signal level threshold for complete dressing.
Process Maximum:	Indicates if the Process signal of any zone has risen above themaximum threshold set.
