NC press brake - Testing of the accuracy 1 Scope This standard specifies the inspection requirements, allowable values and inspection methods for the accuracy of NC press brake. This standard is applicable to the NC press brake. 2 Normative references The following referenced document is indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition (including any amendments) applies. GB/T 8170 Rules of rounding off for numerical values & expression and judgment of limiting values GB/T 10923-2009 Test code of accuracy for metal forming machine 3 Inspection requirements 3.1 General requirements 3.1.1 The installed press brake shall be adjusted to be leveled before the inspection of accuracy, which shall not exceed 0.20/1,000 in the longitudinal and transverse directions. 3.1.2 The geometric accuracy and numerical control accuracy shall be inspected under the condition of no load. 3.1.3 The accuracy inspection shall be carried out after full load test. 3.1.4 During the accuracy inspection, the mechanism and parts affecting the accuracy shall not be adjusted. 3.1.5 The accuracy inspection and inspection gauge shall comply with GB/T 10923. 3.1.6 When the actual measured length is less than the length specified in the tolerance clause, the accuracy shall be converted according to the actual measured length, and then rounded to micron digits according to GB/T 8170. 3.1.7 The limit deviation of specimen length and width is ±2mm, and that of specimen thickness is ±0.3mm. 3.1.8 For multi-motor synchronization NC press brake, the geometric accuracy and working accuracy are inspected on single machine respectively. 3.2 Working accuracy inspection conditions 3.2.1 The specimen length shall meet the requirements of Table 1.
