DMIS - Sensor Setting
An excerpt from the DMIS Handbook. Learn how to write programs in DMIS. This book will help you master the DMIS Language.
In these DMIS articles we will start with the basics and move to more complex DMIS statements
Syntax:
SNSET/setting_type (,reference), value
DMIS syntax at the beginning of a program.
SNSET/APPRCH, 5.0000, ON
SNSET/RETRCT, 5.0000, ON
SNSET/SEARCH, 50.0000
SNSET/DEPTH, 3.0000, 3.0000
SNSET/CLRSRF, 30.0000
Again, your software input may look different, but it is shown here to demonstrate how a CMM software allows the input that will be written in the DMIS code.
APPRCH
Approach controls the distance from a feature nominal that the CMM will depart the POSVEL (Position Velocity) and move into MESVEL (Measurement Velocity).
SEARCH
Search controls how far the CMM will search for a touch point along the normal vector set in the nominal feature statement.
RETRCT
Retract controls the distance the probe will move away from a probed touch point.
Here we changed the retract to 8mm with a 5 mm approach
Care must be taken in a diameter, slot, etc..., any feature with an opposing wall so that either the approach or the retract will not the wall.
CLRSRF
CLRSRF – provides the clearance plane height for the stylus to travel to the next feature.
CLRSRF
Green - Path with reference
Red - Path without reference
Yellow - CLRSRF
Example:
SNSET/CLRSRF, 30.0000
Sets the clearance surface height to 30mm
This is an easy way to understand CMM programming in native DMIS. Learn the secrets to higher level DMIS programming with the DMIS Handbook.
