Generally, tool compensation in CNC refers to the wear caused by the cutting tool during the cutting process, which forms a positive tolerance. Therefore, adding tool compensation in the CNC panel can only directly eliminate the wear recommendations and avoid re-tooling to save time. Theoretically speaking, the tool will only wear out, the gap will become larger, and there will be no need to reduce the compensation value. Unless the tool is changed, it must be re-calibrated.
The original intention of tool compensation is to allow users to program without considering the size of the tool, but to program directly according to the contour size of the workpiece. Otherwise, the tool is always changing, the program needs to be constantly changed, and problems such as excessive before and after must also be considered.
Generally, tool compensation is divided into two parts:
1. Radius compensation
2. Length compensation
(1) When programming, it is regarded as the movement of a point to compile the movement trajectory. In fact, the tool always has a certain radius of the tool or the arc radius of the tool tip, so the movement trajectory of the tool position point during the contour processing of the part It is not the actual contour of the part. There is a tool radius difference between them. In order to make the motion path of the tool location point coincide with the actual contour, it must be offset by a tool radius. This offset is called tool radius compensation
(2) Tool length compensation is the tool position compensation for the tool tip to reach the programmed position.
You can refer to the relevant machine tool manual to set the relevant compensation in the parameters to ensure the accuracy of the processing.

The slotting machine is actually a vertical planer, which belongs to the same category as the bull’s head planer in terms of structural principles. The linear reciprocating motion of the inserting knife in the vertical direction with the ram is the main motion, and the intermittent motion of the workpiece in the longitudinal, transverse and circumferential directions is the feed motion. The production efficiency of the slotting machine is low, the surface roughness Ra of the machined surface is 6.3-1.6 microns, and the perpendicularity of the machined surface is 0.025/300 mm. The main parameter of the slotting machine is the maximum slotting length.
The main purpose is: it is used for processing inner keyway or spline hole in single or small batch production. It can also process flat, square or polygonal holes, etc. It is often replaced by milling machine or broaching machine in mass production.
The main parameter of the broaching machine is the rated tension.
Broaching
A machine tool that uses a broach as a tool to machine through holes, planes and shaped surfaces of workpieces. Broaching can obtain higher dimensional accuracy and smaller surface roughness, high productivity, and suitable for mass production. Most broaching machines only have a broach for the main motion of linear broaching, but no feed motion. In 1898, J.N. Lapointe of the United States manufactured the first mechanical transmission horizontal internal broaching machine. In the 1930s, a double-cylinder vertical internal broaching machine was manufactured in Germany, and a large flat side broaching machine for processing cylinder blocks was manufactured in the United States. In the early 1950s, continuous broaching machines appeared.

CNC lathes and turning centers are high-precision and high-efficiency automated machine tools. Equipped with multi-station turret or power turret, the machine tool has a wide range of processing performance, and can process linear cylinders, oblique cylinders, arcs and various threads, grooves, worms and other complex workpieces. It has linear interpolation and arcs. Interpolate various compensation functions, and play a good economic effect in the mass production of complex parts.
The Programmable Logical Controller (PLC) is also a general-purpose automatic control device based on the proud processor. It is also called a Programmable Controller (PC) or Programmable Machine Controller (PC). Programmable Machine Controller, referred to as PMC), is used to complete various logical operations and sequence control of CNC machine tools, such as machine start and stop, workpiece clamping, tool replacement, coolant switch and other auxiliary actions. The PLC also accepts instructions from the machine tool operating panel: on the one hand, it directly controls the actions of the machine tool; on the other hand, it sends related instructions to the CNC for processing control and creation. The PLC in the CNC system has a built-in type and an independent type. The internal I type PLC and CNC are combined and designed, also known as the integrated type, which is a part of the CNC; the independent type PLC is produced by an independent professional factory, also known as the exterior type.
The operation of the CNC machine tool is realized through the man-machine operation panel, which is composed of the CNC panel and the machine tool panel.
The numerical control panel is the operation panel of the numerical control system, which is composed of a display and a manual data input (Manual Data Input, referred to as MDI) keyboard, also known as an MD panel. The lower part of the display is often provided with a menu selection key, which is used to select a menu. In addition to various symbol keys, number keys, and function keys, the keyboard can also be set with user-defined keys. The operator can realize the system management through the keyboard and the display, and input, store, edit and modify the numerical control program and related data. During processing, the screen can dynamically display system status and fault diagnosis reports. In addition, the numerical control program and data can also be imported through the disk or the communication interface box.
The machine tool operation panel is mainly used for the operation of the machine tool in the manual mode, and the operation of the machine tool in the automatic mode. There are various buttons and selection switches on it, which are used for the start and stop of the machine tool and auxiliary equipment, the selection of processing methods, the selection of speed and override, etc.; there are also digital tubes and signal display. The operation panel of medium and small CNC machine tools is often integrated with the CNC panel, but there is a clear boundary between the two. The communication interface of the numerical control system, such as a serial interface, is permanent and located on the machine operation panel.
