The spiral toolpath did not completely cover the area left by the contour toolpath, so I needed to use a second finishing toolpath to cover the area it missed. This also contributed to a further improvement in surface quality.

Steam motor

One of my inspirations was a beautiful brass model of a steam engine from Engineman.

Organize all sketches, photographs, specifications, or other details about the part. View them, organize them, and make them available for easy use when creating a CAD model.

Another approach to consider is raster tracing or vectorization. If you have photos of a part you want to take, many CAD programs will allow you to upload the photos, scale them, and either trace or automatically vectorize the elements you see in the photos. This way they will be accurately modeled using CAD software.

In some cases, accuracy is not particularly important. For example, when modeling a decorative part in a wood carving application.

Classification of metal-cutting machines, their types and types

Units for processing metal products are divided into nine large groups. In accordance with this division they can be:

turning (group code – 1);
boring and drilling (code – 2);
finishing, grinding, sharpening and polishing (code – 3);
special (code – 4);
thread- and gear-processing (code – 5);
milling (code – 6);
split (code – 7);
slotting, planing, lingering (code – 8);
different (code – 9).

The units of each group, in addition, are usually divided into different types:

lathes: multi- and single-spindle, as well as specialized (a subgroup of semi-automatic and automatic machines), revolving, multi-cutting copying, rotary, drilling and cutting, special, frontal;
boring and drilling metal-cutting machines: semi-automatic multi- and single-spindle, vertical, radial and horizontal drilling, coordinate, diamond and horizontal boring, various drilling machines;
polishing and other installations of the third group: roughing, internal, cylindrical and surface grinding, sharpening, specialized;
units for processing teeth and threads: gear hobbing, gear cutting (their device allows processing conical wheels), gear cutting (cylindrical wheels), thread cutting, thread and gear grinding, checking and gear finishing, thread milling, for working with the ends of teeth, for worm machines steam;
metal-cutting milling machines: continuous, cantilever (vertical, wide-universal and horizontal), longitudinal, non-cantilever vertical, engraving and copying;
planing and similar equipment: longitudinal with two or one stand, broaching (horizontal and vertical), transverse planing, slotting;
cutting units: with a smooth disk, with an abrasive wheel, with a cutter, saws (hacksaw, disk, band), straightening and cutting;
various metal-cutting machines: dividing units, for monitoring grinding wheels and drills, balancing, filing, centerless and straightening, tangential sawing.

In addition, the equipment we are interested in is divided into the following types:

by geometric dimensions and weight: large, unique and heavy;
by level of specialization: special (metal-cutting machines for working with products of the same standard sizes), specialized (the sizes of the processed parts are different, but they belong to the same type), universal (allow you to work with any products);
in terms of accuracy: P (increased accuracy), N (normal), A (especially high), B (high), and also C (precision), the latter units are also often called particularly accurate.

Marking of units for metal processing

As you yourself understand, the classification to which metal-cutting machines are subject was invented for a reason, but so that a specialist can instantly determine the type, basic structure and operating features of the machine, the symbol of which he sees in front of him.

The marking of different machine models is a few numbers and letters, which encrypt basic information about the unit. The first number indicates the group of the machine, the second – its type, the third (sometimes also the fourth) – the standard size.

If any letter appears at the end of the code (after all the numbers), it tells us about certain special characteristics of the machine, its level of accuracy, or that the equipment has been modified. But the letter after the very first digit in the marking of a metal processing unit indicates that it has undergone modernization (or it is a different version of it, different from the basic version).

To make the coding principles clear to you, let’s decipher the markings of the 6M13P machine. By the first digit we can easily determine that it is milling, classified as the first type of milling equipment (number 1), has a 3rd standard size, belongs to high-precision units (the last letter in the code), and has been modernized (the first letter after the first letter).

Level of automation and other equipment features

Metal-cutting machines used for mass and large-scale production are called aggregate machines. Their structure is approximately the same; they are produced using standardized work tables, work heads, beds, spindles and other components. If machines are manufactured for single and small-scale production, their design may be unique.

According to the level of automation, the units we are considering are:

Semi-automatic. They install the workpiece to be processed, start up the equipment, and dismantle the product after processing by a person. The remaining procedures, classified as auxiliary, are performed automatically.
Automatic. Such machines need to be set up (set the necessary conditions for processing a particular batch of products) and launched. They will perform all work operations themselves.

CNC machines (computer numerical control) deserve special mention. Their work is “guided” by a special program containing a coded complex of numerical values. Such a program sets all the working operations of the machine, starting from the rotation speed of its working tool and ending with the speed of execution of a specific process.

Modern CNC systems contain the following mandatory elements:

Operator console (console). It makes it possible to enter a program, transfer metal-cutting machines to manual operation mode, set equipment operating modes, and so on.
Controller. A special device on CNC units that sets and monitors the accuracy of technological control commands, the trajectory of movement of the working device, is responsible for changes and general control of the machine, and also performs additional calculations. These days, a controller can be a powerful industrial computer, a logical programmable device, or a conventional microprocessor.
Operator panel (screen, display). This CNC element is designed so that the specialist working at the machine can visually observe the process of processing products, and, if necessary, make any changes to the control program.

The essence of operating CNC equipment is relatively simple. First, a control program is compiled for metal-cutting equipment, which is entered into the controller by the operator (a programmer is used for these purposes). When the unit is turned on, the CNC issues sequential commands to the machine components. After completing all commands for processing the part, the equipment turns off.

The high accuracy and speed of performing work operations, which characterize metal-cutting machines equipped with CNC, have led to their active use as part of automatic workshop lines and very large production automated systems.

Brief information about the design of metal-cutting units

The machines of different groups and types that we describe have many common features in their design. Their design is based on the fact that all technical devices and mechanisms installed on the units must guarantee the ability to perform two movements:

feeding the cutting device or workpiece;
direct cutting movements.

To ensure the indicated movements, as well as the stable operation of all equipment, a metal cutting machine must have the following structural elements:

controls (responsible for starting the unit and stopping it, necessary for constant monitoring of the operation of the machine);
transmission device (it is needed to transmit movement from the engine to the actuator and to convert movement);
drive (electric, mechanical, pneumatic, hydraulic);
actuators (devices for cutting metal are placed on them; it is these mechanisms that carry out metal processing).

Set the X and Y axes to zero

For my part, since I had plenty of extra stock, I only needed to mark the center of the piece with pencil lines. I then used a pointed tool to grab the pencil cross to set the X and Y axis zero points.

The excess stock gave me enough room for error to keep the finished shape within the confines of the piece of raw wood I used.
