Method for automatic measurement and setting of workpiece plane of machine tool measuring head

Abstract

The invention belongs to the field of numerical control machining and particularly discloses a method for automatic measurement and setting of a workpiece plane of a machine tool measuring head. The method comprises a first step of selection of a basic measurement program of a numerical control system; a second step of selection and allocation of measurement parameters; a third step of structuraldesign of the measurement program; a fourth step of parameter design of a measuring head motion track required for measurement; and a fifth step of comparative judgment of measured values. Through themethod, programming optimization is performed according to measurement operation required in actual machining; and by inputting track programming parameters required for the measurement, complicatedand tedious G-code programming is simplified, convenience is brought to common operators and programmers, and product quality and working efficiency are improved.

Description

technical field [0001] The application belongs to the field of numerical control machining, and specifically relates to a method for automatically measuring and setting workpiece planes by a machine tool probe. Background technique [0002] Machining technology generally follows the "positioning-processing" operation mode. According to this mode, how to realize the precise positioning of the processed workpiece according to the design and process requirements has become a primary issue to ensure the qualified processing of the workpiece. The alignment and setting of the Z0 plane in NC machining is a necessary process of NC machining. The traditional alignment method is that the operator uses a standard tool setting block to set the tool on the machine tool to find the position of the Z0 plane reference, and then use the calculation function of the machine tool or Manually input relevant data into the numerical control system to set the coordinate system of the workpiece. Thi...

Problems solved by technology

In batch processing, due to the cumbersome operation, operators often use random spot checks to check and set Z0, which may lead to undiscovered consequences of incorrect clamping of unsampled workpieces, resulting in the occurrence of out-of-tolerance scrapping of workpieces

Most of the parts in the aviation manufacturing industry are complex in shape, high in process requirements, and expensive in materials. The out-of-tolerance scrapping of parts due to operational errors has brought huge losses to the company.
