Rules for Sample Making
When making plush toy samples, pay attention to the production principles of straight lines, arcs, angles, proportions, symmetry and positioning of the samples. The textual description should be written on the front of the samples. The principles for making a sample are as follows: the straight lines of the sample should be straight, the arcs should be smooth, the knife holes should reach, and the angles and proportions should be consistent. Templates with center lines such as trapezoids should be symmetrical on both sides. The straight lines opposite the edges of the rectangular template should be kept parallel. The positioning points should be accurate. The positioning points used for splicing or provincial roads should be consistent without any omissions.
The allowable error range of the sample
When replicating production samples, attention should be paid to accuracy and consistency with the original samples. For samples with a length of less than 10cm, there must be no error. For those with a length of more than 10cm, the error is generally within the range of 0.5cm. To maintain the accuracy of the sample, it is necessary to check the degree of deformation of the sample and frequently compare it with the original sample during use. If there is any damage or deformation, it should be replaced in time. When the fabric shrinks due to different materials or processes after cutting, it is advisable to consider enlarging the sample size, but this can only be confirmed after sealing the sample.
The marking requirements for the sample
In order to facilitate the correct identification of the sample, the marking of the sample is very important. The marking of the sample includes: product model, product name, part name and sample number, and material name (processing requirements). Thread flow direction, number of cut pieces, positioning marking. All the above contents should be marked on the sample. If the sample area is too small to mark all the contents, the sample number should be marked and it should be prompted to refer to the process technical requirements sheet. At the same time, the corresponding content should be found on the process technology requirements sheet. Controlled signs should be marked on the sample. The original sample should be stamped with the control seal of the technical department, and the production sample should be stamped with the control seal of the production department. The control seal should have the name or code of the person sealing the sample.
Copy the quality requirements of the sample
The accuracy of replicating production templates is a prerequisite for ensuring the accuracy of cutting pieces. The quality requirements for replicating the template are: precise shape, correct marking, and complete information.
Interpret the layout diagram
The layout diagram is a schematic diagram indicating the arrangement of each sample at the minimum material usage. The layout diagram usually indicates the general information of the wire flow or hair direction of the sample, the reverse and forward arrangement or the same direction arrangement of the sample, and the sample nesting.
When performing the cutting operation, based on the information indicated in the layout diagram and the requirements of the production batch, calculations and layout should be carried out to calculate the unit cutting piece quantity. Discharge materials in the way that consumes the least amount of materials.
Use a digitizer or industrial photography to convert it into vector graphics for sample layout
Nowadays, digitizers are widely used in sample layout. Digitizers are a kind of graphic input device with very wide applications in professional fields, consisting of electromagnetic induction plates, cursors and corresponding electronic circuits. When the user moves the cursor on the electromagnetic induction plate to the designated position and aligns the intersection point of the cross with the digitized point, pressing the button, the digitizer will arrange the corresponding command symbol and the coordinate value of that point position into an ordered set of information, and then transmit it to the main computer through the interface (mostly serial interface). A digitizer is a super-large writing pad. Users can write or draw graphics on it with a special electromagnetic induction pressure-sensitive pen or a smooth brush and transfer them to the computer system. However, in terms of software support, it is quite different from the graphics tablet, and in terms of hardware design, each has its own emphasis.
Industrial photography is carried out with high-precision cameras, and then the graphics are vectorized and transformed through software, making layout more convenient and faster.
During the layout process of plush toy samples, large-scale drawings need to be drawn. It is impossible to fully complete the drawing process relying solely on the CAD system, and there will also be significant deviations in precision. Therefore, methods such as converting to vector graphics through digitizers or industrial photography must be adopted to meet the layout requirements.
The PGM TC series fully automatic cutting machine system is a perfect combination of model rooms and cutting rooms. Highly integrated with automation, software, fabric cutting and other technical functions, it automatically completes the entire process of pattern making, material arrangement, fabric laying and cutting.
