A method for automatic measurement and setting of workpiece plane by machine tool probe

Abstract

This application belongs to the field of numerical control machining, and is specifically a method for automatically measuring and setting a workpiece plane by a machine tool probe, which includes the following steps: Step 1, the selection of the basic measurement program of the numerical control system; Step 2, the selection of measurement parameters and Assignment; Step 3, measurement program structure design; Step 4, parameter design of the probe motion trajectory required for measurement; Step 5, comparison and judgment of measured values. This application optimizes the programming based on the measurement operations required in actual processing. This method simplifies the complicated and cumbersome G code programming by parametrically inputting the trajectory programming required for measurement. Bring convenience, improve product quality and work efficiency.

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.
