Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the examples, which are explanations of the present invention rather than limitations.

[0029] A kind of PDC drill processing method based on machine tool programming, comprises the following operations:

[0030] 1) The flow channels of the PDC drill bit are respectively established as EspritCAM free-form surface features (that is, the outer surface of the drill bit), and these established free-form surface features will be used for rough and fine milling. Use the macro function of EspritCAM software to record the operation process of selecting free-form surface features into a macro, and package it into a DLL file to make an external plug-in and load it into the software with icon commands. In order to identify more accurately, the VB code that is recorded as a macro and opened in the EspritCAM macro function can be used to generate a new macro suitable for the quick selection of the f...

Abstract

The invention discloses a PDC drill bit machining method based on machine tool programming. In a special structure of a PDC drill bit, repeated characteristics are searched and utilized, the sizes areconsistent, and the cause of larger workload is that the characteristics are not in the same plane, so that a machining coordinate system needs to be continuously changed to realize programming of the characteristics; according to the PDC drill bit machining method based on machine tool programming, the machining of flow channels, teeth and holes is combined with machining plane coordinate systems, and the previous numbered procedures of a process manager are applied to the characteristics through an automatic characteristic identification function, so that the programming time is shortened to 30 minutes to 1 hour; and the templated operation is realized, technicians with general programming levels also can start and operate quickly, so that programming time is shortened, programming workefficiency is improved, and then machining efficiency is further improved.

Description

technical field [0001] The invention belongs to the technical field of petroleum steel body PDC drills, and relates to a processing method of PDC drills based on machine tool programming. Background technique [0002] Petroleum steel body PDC drill bits have a special structure, such as each cutting tooth, each water hole position, has its own different spatial angle position, and according to the size of the drill bit, the number of these cutting teeth ranges from a dozen to hundreds There are several to more than a dozen water holes. The characteristics of so many different planes require a lot of repetitive operations when using a five-axis machine tool to process and program petroleum steel PDC drill bits, which consumes a lot of time and energy, and some highly skilled personnel need 5-8 hours. to complete all procedures. Contents of the invention [0003] The problem to be solved by the present invention is to provide a PDC drill bit processing method based on mach...
