Problems solved by technology

However, based on the traditional NC program operation control method, it only includes the laying path and the connecting path. For laying problems, the positioning and relaying of defective tows can only be manually intervened, manually stop and run to the starting point of laying defective tows laying, or directly relying on t

Example Embodiment

[0035] The present embodiment discloses an automatic fiber placement program execution control method of the present invention as a basic embodiment, comprising the steps of:

[0036] Step S1: Planning composite fiber placement trajectory, generates several strips 5 for each ply, as figure 2 FIG, 5 is provided with four strips, each strip 5 contains fiber placement device placement strip path 5 to complete the deposit must pass 1;

[0037] Step S2: establishing relative positional relationship between the model and the automated fiber placement equipment model, set as a fixed point placement safe anchorage point 6 in the device coordinate system;

[0038] Step S3: for each strip 5, generates motion path without mutual interference of the three;

[0039] Step S4: Based on the movement path of the deposit safe anchorage point laying path 1 in step S1, step S2 and step S3 6 plated NC program is provided;

[0040] Step S5: automatic fiber placement NC part program based on placement, ...

Example Embodiment

[0042] Example 2

[0043]This example discloses an automatic screen operation control method, as a preferred embodiment of the present invention, in Example 1, the placement of safe bell point 6 away from the laying model to ensure automatic paving equipment In the moving safety berth point 6, there is no interference between the paving model; in step S3, the three mutually immistent motion paths are: detergent path 2, and the laying of safe beverage points 6 to the starting path of 1 Motion path; backhaul path 4, laying path 1 end point to the motion path of 6 safe beverage points; transition path, the current strip 5 Paving path 1 end point to the next belt 5 pickup path 1 starting point Connection path, such as figure 2 Indicated.

[0044] Further, in step S4, the setting NC program includes a set web program that includes the following steps:

[0045] Step S41-1, based on the paver path 1, the paving safety bell point 6 and the motion path editing the NC code, including the de...

Abstract

The invention belongs to the technical field of prepreg tow automatic laying forming and particularly relates to an automatic tow laying program operation control method. The method comprises steps that an automatic composite material tow laying track is planned, a plurality of strips are generated for each laying layer, and each strip comprises a laying path through which automatic tow laying equipment must pass to complete strip laying; a relative position relation between the laying model and the automatic fiber laying equipment model is established, and a fixed point under an equipment coordinate system is set as a laying safety mooring point; for each strip, three motion paths without mutual interference are respectively generated; and an NC program is set, and automatic fiber placement parts are laid in the NC program. Compared with the prior art, according to the method, safe and automatic returning to a laying safety mooring point is achieved, then functions of automatic fiber laying problem automatic returning, rapid re-laying and the like are achieved, laying efficiency is improved, the manual participation amount in the laying process is further reduced, and the equipment operation risk is reduced.

Description

technical field [0001] The invention belongs to the technical field of automatic laying and forming of prepreg tow, and in particular relates to an automatic laying program operation control method. Background technique [0002] With the rapid development of composite material technology and its processing technology and inspection and maintenance technology, the amount of composite materials used in military and civilian aircraft is increasing significantly. The automatic production process of composite materials represented by automatic tape laying and tow laying has greatly improved. Application of composite materials in aircraft structures. The automatic laying technology uses a multi-axis linkage laying head to bundle multiple bundles of prepreg tows into a variable-width prepreg according to the path planned by the process through the functions of feeding, heating, laying, compacting, cutting, and restarting. The technique of laying down the tape after dipping it on t...
