This section GB/T 16857 Part 2.

This section is in accordance with the rules given GB/T 1.1-2009 drafting.

This Part replaces GB/T 16857.2-2006 "Geometrical Product Specifications (CMM) CMM acceptance testing and re-inspection Part 2. Coordinate measuring machine for measuring dimensions ", compared with GB/T 16857.2-2006, the main technical changes are as follows.

--- Modify the standard name;

--- Increase the length of the probe when the bias is 150mm measurement error E150;

--- Increased length measurement error repeatability R0;

--- Canceled the shortest block length of not more than 30mm requirements;

--- Details of the use of laser interferometer method;

--- Increase the low expansion coefficient standard than the measurement requirements;

--- Unfavorable retest times reduced from 10 to 3 times;

--- The detection error is transferred to GB/T 16857.5.

This section uses the translation method identical with ISO 10360-2.:2009 "Product Geometrical Specifications (GPS) Coordinate Measuring Machine (CMM) Acceptance testing and retesting testing - Part 2. Coordinate measuring machines for measuring linear dimensions ".

1 Scope

GB/T 16857 provisions of this part of the coordinate measuring machine for measuring linear dimensions, in accordance with the manufacturer given the performance indicators Acceptance test verification method. At the same time, also provides the user to the measuring machine periodic re-examination of the verification method.

This part of the acceptance testing and re-inspection detection method is only applicable to discrete point detection mode contact detection system Cartesian Coordinate Measuring Machine.

This section does not explicitly apply to.

--- non-Cartesian coordinate measuring machine coordinate; with the consent of the parties, this section can also be used for non-Cartesian coordinate measuring Measuring machine.

--- coordinate measuring machine using optical probe; with the consent of the parties, this section can also be used for optical measuring head coordinate measuring machine.

This section specifies the manufacturers or users specify the CMM characteristic indicators of acceptance testing or re-examination of the detection methods and inspection the rules of consistency.
