Embodiment 1

[0072] refer to figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the deep hole drilling programming method according to the embodiment of the present invention.

[0073] In Embodiment 1, the method for deep hole drilling programming includes:

[0074] Step 101, obtaining the hole features of the pre-selected hole model;

[0075] Preferably, said obtaining the hole characteristics of the pre-selected hole model includes:

[0076] Obtain the coordinates of the normal direction of the six surfaces of the pre-selected hole model;

[0077] converting the data of the pre-selected hole model into the coordinates of the normal direction of the six curved surfaces;

[0078] A hole feature is obtained according to the data in the transformed coordinates.

[0079] Specifically, this application uses a three-dimensional digital model of a hole model generally generated by other CAD software. For example, a 3D digital model file containing hole elements is g...

Embodiment 2

[0118] refer to figure 2 , figure 2 It is a schematic flowchart of the second embodiment of the deep hole drilling programming method according to the embodiment of the present invention.

[0119] On the basis of Embodiment 1, after obtaining the checked hole features according to the hole features and the preset checking algorithm, it further includes:

[0120] Step 103, generate a dotted tool path according to the checked hole features, and the dotted tool path is used to identify the position of the hole to be deep drilled.

[0121]Specifically, after the feature filtering of holes is completed, a dotted tool path must be generated before the deep hole drilling tool path is generated. The dotting toolpath here refers to all the hole features on the same surface, which are all generated as the same dotting toolpath.

Embodiment 3

[0123] refer to image 3 , image 3 It is a schematic flowchart of the third embodiment of the deep hole drilling programming method according to the embodiment of the present invention.

[0124] On the basis of Embodiment 1, after obtaining the checked hole features according to the hole features and the preset checking algorithm, it further includes:

[0125] Step 104, generating a tool path for deep hole drilling according to holes of different diameters;

[0126] Step 105 , when generating the tool path for the deep hole drilling, if an intersecting hole is encountered, at the hole breaking position, the acceleration and deceleration are automatically performed at a corresponding rate according to a certain ratio.

[0127] Specifically, for the deep hole drilling process, after the dotting tool path is generated, the tool paths for deep hole drilling must be generated according to different diameters in the same normal direction of the surface. When generating the drill...

Abstract

The embodiment of the invention discloses a deep hole drill programming method and device. By obtaining hole features of a hole model selected in advance, the hole features after checking are obtained according to the hole features and a preset checking algorithm, wherein the checking algorithm comprises diameter checking, checking of the hole depth corresponding to the diameter, checking of concentric through holes in opposite directions, checking of concentric blind holes in the same direction and / or deletion of a centre hole, so that programming of full-automatic deep drilling is achieved, the programming workloads of programmers and machining personnel can be greatly reduced, the machining quality of a deep hole drill is improved, and the machining efficiency is also improved. As the efficiency and quality are both considered, the service life of a drill bit is prolonged, and the production cost is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of mechanical processing, and in particular to a method and device for deep hole drilling programming. Background technique [0002] In mechanical processing, for deep holes with a ratio of hole depth to hole diameter greater than 6, gun drilling is generally used for deep hole drilling. The current method of generating NC code files for deep hole drilling can be manually programmed, or generated by human operation using CAM software. [0003] Among the two current programming methods, due to the complexity of the model and the large number of holes, in the current mechanical industry, CAM is generally used for auxiliary deep hole drilling programming. However, the existing method of using CAM software programming is that the programmers or processing personnel manually operate the programming software, manually find the holes on each surface of the model that need to be processed,...
