Problems solved by technology

[0011] However, this arrangement does not allow cutting along the width and / or length of the sheet (i.e. along its major dimension), but only in the thickness direction
In particular it no longer allows cutting with complex trajectories, as is the case with sinusoidal trajectories

Embodiment Construction

[0074] figure 1 and 1A A cutting device 1 is shown for cutting out a workpiece 2 from a blank block B made of metallic or composite material having a length L, a width 1 and a thickness E (see figure 1 and 1A dotted line in and see Figure 1B ). The device has a guide 3 along a defined trajectory 4 (dashed line), for example as Figure 1C Curve 5 shown in .

[0075] More precisely, curve 5 is defined by point M(x 0 ,y 0 ), where x 0 and y 0 is a function of the parameter t such that:

[0076]

[0077] and

[0078] This trajectory defines a cutting strip 6 with a width 2e, itself defined by the data of the curves 7 and 8 with a distance of 2e between them. The cutting strip (trait de coupe) is centered on the curve 5 which also forms the neutral line (fibre neutre) of the cutting.

[0079] Curves 7 and 8 are then defined as follows:

[0080]

[0081]

[0082] The device 1 has a circular chain saw 9 (see figure 1 ), the circular chain saw 9 is driven on ...

Abstract

The invention relates to a device, a method for cutting a set of workpieces in a blank block B made of metal or composite material along a defined trajectory, and the cut set of workpieces. The device has a guide (3) forming said trajectory and a support (chainsaw 9) slidably mounted in the guide, said support having a lateral disc (23) with at least one cutting blade ( 24), the cutting blade is equipped with a raised cutting edge (25) for cutting along the normal direction (26) with respect to the lateral disc.

Description

technical field [0001] The invention relates to a cutting device for cutting workpieces made of metallic or composite materials along a defined path. [0002] The invention also relates to a cutting method for cutting such workpieces made of metal or composite material along defined trajectories and the workpieces obtained using this method. [0003] The present invention, although non-exclusively, is particularly widely used in the field of cutting mechanical workpieces with high hardness, that is, with a Rockwell hardness greater than 30, especially for forming metal materials such as can be used in the aerospace field (especially Aluminum, titanium, steel) or composite material (especially with carbon fibers and a thermosetting or thermoplastic matrix) rough workpiece. Background technique [0004] More precisely, in the case of the manufacture of metal mechanical workpieces, it is known to start from a blank of raw material, for example a billet of cast iron, which is t...
