CNC milling small worm - Part 1. Testing of the accuracy
1 Scope
This section GB/T 25660 specifies the geometric precision CNC milling small worm, location accuracy and precision requirements and testing
Testing method.
This section applies to a maximum workpiece diameter 80mm, maximum modulus to 3.5mm CNC machining small worm milling machine (hereinafter referred to as
"machine tool").
2 Normative references
The following documents contain provisions which, through reference GB/T 25660 in this section constitute provisions of this section. For dated reference documents
Member, all subsequent amendments (not including errata content) or revisions do not apply to this section, however, encouraged to reach under this section
Parties to research agreement to use the latest versions of these documents. For undated reference documents, the latest versions apply to this
section.
GB/T 10089-1988 cylindrical worm and precision
GB/T 17421.1-1998 Test code for machine tools - Part 1. under no-load or finishing conditions Geometric accuracy of machines (eqv
ISO 230-1.1996)
GB/T 17421.2-2000 Test code for machine tools - Part 2. CNC axis positioning accuracy and repeatability of determination
(Eqv ISO 230-2.1997)
3 General requirements
3.1 section all linear dimensions are in millimeters (mm) as the unit; angle deviation is mainly represented by the ratio. In some cases the
Clear, but also with microradians (μrad) or arcsec ( ") as the unit in terms of its relationship formula below.
0.010/1000 = 10 × 10-6 = 10μrad≈2 "
3.2 Use this section shall GB/T 17421.1, especially heating pre-installation testing tools, spindles and other moving parts, testing
Recommended methods and inspection precision tools. Installation of the machine level and ambient temperature should meet the following requirements.
--- According to GB/T 17421.1-1998 3.1 Adjustment of the machine installation level. The level meter on the mounting plate, a level in
Vertical and horizontal readings are not more than 0.04/1000;
--- When test, the ambient temperature should be maintained at 20 ℃ ± 2 ℃. Machine Tool and Gage placed a long enough time in the measurement environment to
Ensure steady state is reached before the test.
3.3 part of the order given in the test project does not represent the actual inspection order. In order to facilitate assembly and disassembly inspection and testing tools, according to any one of
Italian order of inspection.
3.4 inspection tools, according to the structural characteristics of the machine does not have to test all the items in this section. For the purpose of acceptance testing requirements
When, by the user to obtain the manufacturer agreed to choose some interesting test items, but these items should be clearly stated at the time of ordering the machine.
Test tools specified in section 3.5 of example only, you can use the same indicates the amount and precision of other inspection tools. Indicators should have
0.001mm or higher resolution.
3.6 working accuracy test, test specimens shall be carried out after finishing.
3.7 When the software can be used to compensate for some of the test items deviation, the user and the manufacturer's protocol press, can use or not use these compensation
Inspection-related projects under the circumstances. When using a software compensation, should be indicated in the test project.
3.8 When the length of the measured length with the provisions of this section are not at the same time, it should be able to measure the length tolerance GB/T 17421.1-1998 in
Provisions 2.3.1.1 translated. Result of the conversion is less than 0.002, based upon the 0.002 meter.
3.9 axis parallel to the axis of the spindle axis is Z-axis perpendicular to the spindle axis of the X-axis.
