Technological map for manufacturing wood products. Technological map for making a cutting board and its features. Lesson topic: “Technological documentation”

A kitchen board is an indispensable element when preparing food. The technological map for making a cutting board allows you to build a high-quality wooden craft under modern conditions.

The technique of artistic processing of wooden products was used back in the 9th century. Wooden crafts have been made by many generations of craftsmen. For this purpose, wood of different species was used, characterized by different artistic qualities: texture, natural structure of the trunk, knots.

Burning as an advantageous way to process materials

Decorative wood processing is performed in various ways, including artistic burning. This craft is very popular and inextricably linked with folk traditions. Its development was accompanied by other types of processing:

  • carving;
  • turning;
  • mosaic;
  • artistic painting.

Burning diversified these arts, but gradually turned into independent types of creativity.

Several decades ago, steel rods were used to make kitchen cutting boards, their tips heated by fire. It was practiced to use special figured stamps, through which relief patterns were engraved.

In modern production, electric burners are used. They include a transformer for converting electrical current, an electrical cable and a handle with a rod. To perform the working part, nichrome wire is used. It simplifies the technological process and allows you to smoothly change the direction of work.

Before starting work, you need to select a workpiece, this will allow you to determine the shape of the product. Any processed wood in the form of:

  • boards;
  • timber;
  • plywood.

The wood must be thoroughly and evenly dried; craftsmen recommend using the center of the log for blanks, as it is less susceptible to deformation. The expression of texture and shade is very important.

Deciduous trees are characterized by the most acceptable qualities for decorative burning. The growth rings are not too visible in them, the texture is quite uniform. Products from the following species will have the best appearance:

  • Linden;
  • poplar;
  • maple;
  • alder;
  • young birch.

The wood must be light in color and not shiny, then the finished product will have an attractive appearance.

It is necessary to pre-treat the surface; this is done with medium and then fine-grained sandpaper.

Board burning technique

Before starting work, you should have a clear idea of ​​the future drawing and the methodology used. There are three types of burning:

  • along the contour;
  • by silhouette;
  • artistic processing.

Burning along a contour is comparatively simple and resembles a pencil drawing of a contour on a sheet of paper. This type is often practiced by many beginners, often this operation is performed with the tip of a rod. Contour burning is convenient for making inscriptions, and when applying an ornament, shading can be applied in this way.

Silhouette burning is performed using two techniques: “smooth stroke” and “annealing”. Using the first of them, it is easy to achieve a smooth black surface. The area processed in this way can be quite large. By quickly moving the needle, different shades of the design are achieved.

When “annealing”, a strip is made along the edge of the workpiece, achieving the designation of the outer contour of the image. The name of this method comes from the nature of the work - annealing the edging.

The artistic or pictorial type of burning is characterized by a combination of the two previous methods. As a result, a three-dimensional image is achieved, taking into account the play of light and shadow. When manufacturing a product, it is necessary to ensure the correct display of objects at different distances in space. The transfer of different structures of objects is achieved by various techniques of shading and shading.

To master the burning technique perfectly, you must have good drawing skills. Regular exercise will improve your powers of observation. They will also help develop the necessary qualities. Before the process itself, craftsmen develop sketches in pencil. This approach will simplify the work on the workpiece.

Multi-board production technique

The manufactured set includes:

  • 2 cutting boards with dimensions 10×170×360 mm;
  • wooden pendant 20×90×360 mm;
  • 2 wooden rods with a diameter of 12 mm and a length of 42 mm.

For manufacturing you will need the following tools and devices:

  • ruler, right angle square, compass;
  • a simple pencil for marking;
  • wood hacksaw;
  • awl;
  • or a drill, but the drill diameter is 12, 20 mm;
  • jigsaw, cutting table;
  • sample;
  • sandpaper;
  • brush, wood glue;
  • mallet;
  • lathe with cutting and through cutters;
  • clear varnish;
  • electric burner.

The design of the board is quite simple.

Manufacturing technology:

Cost Analysis

This set of cutting boards is inexpensive. Pegs can be made from unwanted leftover materials. So little glue is needed that craftsmen recommend not taking its cost into account. You only need to buy wood and varnish.

The average price of wood is about 4 thousand rubles; in the case of the production of cutting boards, the material required is 0.008 cubic meters. meter, the cost will be 32 rubles, and 150 grams of varnish will cost 21 rubles.

Wage costs are determined by half the cost of materials - 26.5 rubles. Other overhead costs - a quarter of the amount of wages and materials - 19.8 rubles.

Adding up all expenses, the total cost of the product will be 99.3 rubles.

Safety precautions during burning

For these jobs, like any other, the specialist is required to comply with safety regulations.

When sawing wood, the master must adhere to the following principles:

  • use limiters and guides;
  • do not allow your free hand to be near the hacksaw blade;
  • Do not blow off the chips; they are swept away with a brush.

When performing work on a lathe, a specialist must perform the following actions:

  • read the occupational safety manual for this equipment;
  • Process only by trained people.

When performing drilling, the master must pay attention to the following rules:

  • install the drill in accordance with the requirements for the machine or drill;
  • the product being drilled must be securely fastened;
  • the drill feed should be carried out without acceleration or jerking;
  • at the exit of the drill, slow down the movement.

When performing paintwork:

  • Do not keep the container with varnish open for a long time.
  • While doing work, do not bring the varnish to your face.
  • The room must be ventilated.
  • It is necessary to use personal protective equipment: protective mask, gloves.
  • Upon completion of work, wash your hands thoroughly using soap.

When using an electric burner:

  • ensure air flow into the room;
  • conductive parts must be reliably insulated;
  • When finishing work, you should turn off the device from the network.

Making boards requires a craftsman to spend approximately 12 hours; the technique is simple and does not require large financial investments. There are a huge number of options for the shape of finished products, as well as their finishing; it all depends only on the imagination of the performer.

This lesson is designed to help you perform the planning and scheduling work of a creative project; it is one of the most difficult elements of the project.

The technological sequence of operations has been developed for artistic turning of wood on a TV-4 screw-cutting lathe using this type of machine, which has a number of advantages over wood lathes.

Advantages of the TV-4 screw-cutting lathe over the DIP wood lathe:

  • The screw-cutting lathe has a set of direct and reverse cams, with which you can process a workpiece up to 120 mm, first installing the reverse cams and turning the finishing base,

Having supported the workpiece with the center of the tailstock, then straight cams are installed, the workpiece is supported by the center of the tailstock and all subsequent operations are performed using the required cutter.

  • This type of machine can be used to process hardwood, as it has a very beautiful natural wood texture compared to softwood, which is recommended to be processed on wood lathes.
  • The cutters in screw-cutting lathes are fixed in a tool holder and are fed to the cutting site using screw mechanisms. More precisely, using longitudinal and transverse feed, which is completely safe compared to working on wood lathes, where the student holds the cutters with his hands, observing the gaps and other conditions for processing wood.
  • If necessary, the workpiece can be easily removed and placed again as necessary for further processing.
  • Boring cutters and any other devices for artistic turning can be attached to the tool holder.
  • The tailstock is used for installing a drill and other cutting tools, as well as for turning a 10-12 degree cone.
  • If a cone of a certain size is needed, it is made using the upper turntable.
  • The rotation speed of the workpiece is changed by switching the handle, which is very important for fine turning and grinding.

Working on these machines is much safer and faster than on wood lathes.

The creation of any product takes place in several stages, and the first of them is the design of the future product.

Don't rush to start making it right away. You can make a mistake, do something wrong, and all the work will have to be redone. No wonder there is a saying: “Measure twice, cut once.”

First you need to make sketches, or outlines, of various options for the future product. Then they analyze in writing the advantages and disadvantages of each option, which allows you to choose the best one.

For the selected product option, technical documentation is developed: a sketch, technical drawing or drawing indicating dimensions.

After preparing the technical documentation, they begin to select high-quality workpieces and mark them. A blank is a material of certain dimensions from which a part will be made (the dimensions of the blank for any part are always larger than the part itself). One or more parts are obtained from the workpiece.

The connection of parts into a product is called assembly.

The transformation of a workpiece into a part or product must strictly comply with the technological process, i.e., a certain sequence of actions.

The technological process of manufacturing a product consists of a number of technological operations. For example, technological operations are sawing out a workpiece on a carpentry bench, drilling holes on a drilling machine, painting the product in a special room, etc.

The sequence of operations for processing a workpiece and making a part from it is recorded in special technological or route maps.

The technological map (Table 6) describes in detail the sequence of technological operations, provides a graphic representation of the workpiece corresponding to each operation, and indicates the tools and devices used.
