Arc Radial Error
Specifies the arc error tolerance to be used when checking the current segment for dimensional
accuracy. All ESSI or EIA programs are comprised of lines, arcs and circles. Arc Radial Error is
used to ensure that the starting and ending radial vectors are within tolerance to describe a valid
geometry.
Auto Closure Detect
This parameter is used to allow the control to detect that it has returned to the starting point. With this
feature ON, the control stops the motion of the tracer when the part is complete allowing a lead-out to
be programmed.
Closure Over/Under Lap
By specifying a positive value for this parameter, the control does not stop the tracer until it has gone
past the start point by the amount of this parameter. By specifying a negative value, the tracer stops
as soon as the tracing head position is within this parameter’s distance of the starting point. This is
only available if the Auto Closure Detect is ON.
Kerf Direction
Selects the desired kerf for cut segments.
Traverse/Pierce
Switches between the traverse and cut segments of the part as it is taught.
Tracing a part
To trace a part while at the Teach Trace screen, select Auto mode, then select traverse or pierce.
You may switch between traverse and pierce during the tracing procedure. Position the optical
sensor near the part drawing and press Start. Use the sensor positioning controls to direct the sensor
towards the part. Once the sensor has located the part, the tracing system will follow the part outline
until completion. When completed, press Done. The part file can now be cut, saved or edited.
Please refer to the instructions provided with your Optical tracing system for further details.
