Chapter 1 Planning Your Measurements
Introduction
1-2 Measurements Reference Guide
Introduction
This guide provides detailed instructions on making measurements with
the Agilent 5530 Dynamic Calibrator. However, before you take a machine
out of production and begin making measurements, it is important that
you plan your measurement carefully. Planning is also an important
factor in increasing efficiency.
This chapter provides guidelines to help you plan your measurement
correctly. Refer to the Agilent 5530 Getting Started Guide for additional
overview information.
Measurement Planning Guidelines
To minimize machine downtime, before making a new measurement
follow these guidelines:
• Determine the travel limits for each axis you will make measurements
on.
• Determine the start position for each axis. Also, determine which
direction is positive and which is negative.
• Make sure the machine’s limit switches are set at the correct
positions.
• Determine what type of position feedback system the machine uses.
Also, determine its thermal coefficient of expansion. To do this, refer
to the machine’s maintenance or operations manual or call the
manufacturer.
• Determine if the machine’s controller is designed to accept an error
correction scheme. If it is, determine the type (for example,
incremental errors or absolute errors).
Before you change the parameters or the error correction look-up
table, refer to the machine tool manual.
• Determine the machine’s least programmable resolution unit.
