锯床系统伺服位置控制模块采用采样插补和预见控制相结合的位置控制（具体控制略），决定关闭送料油缸的位置，使送料油缸停止时刚好达到目标位置。由于电磁机械滞后及运动惯性，通过“通”“断”控制送料滑台移动0.1mm几乎不可能的。为了保证最小送料长度及送料精度，后钳使送料滑台后退到到LK位置，然后向前移动到预测位置LT关闭送料电磁阀。当送料油缸运动停止时后钳夹紧。
圆锯床
圆锯床也称圆锯机，分全自动与半自动。圆锯片作旋转的切削运动，同时随锯刀箱作进给运动。圆锯床按锯片进给方向又分为卧式(水平进给)、立式(垂直进给)和摆式（绕一支点摆动进给）3种。此外还有各种专用圆锯床，如用于切割大型铸件浇冒口的摇头锯床；用于钢轨锯切和钻孔的锯钻联合机床。
带锯床
环形锯带张紧在两个锯轮上，并由锯轮驱动锯带进行切割。带锯床主要有立式和卧式两种。立式带锯床的锯架垂直设置，切割时工件移动，用以切割板料和成形零件的曲线轮廓，还可把锯带换成锉链或砂带，进行修锉或打磨。卧式带锯床的锯架水平或倾斜布置，沿垂直方向或绕一支点摆动的方向进给，锯带一般扭转40°，以保持锯齿与工件垂直。卧式又分为剪刀式、双立柱、单立柱式带锯床；根据使用情况分为手动型（经济型手动送料手动切割物料）、自动型；根据使用控制器的自动化程序可分为手动型（半自动手动送料）全自动型（自动送料自动切割）
弓锯床
装有锯条的锯弓作往复运动，以锯架绕一支点摆动的方式进给，机床结构简单，体积小，但效率较低。弓锯床锯条的运动轨迹有直线和弧线两种。弧线运动时锯弓绕一支点摆动一小角度，每个锯齿的切入量较大，排屑容易，效率较高，新式弓锯床大多采用这种方式。
The servo position control module of sawing machine system adopts the position control combining sampling interpolation and preview control (the specific control is omitted), which determines the position of closing the feeding cylinder, so that the feeding cylinder just reaches the target position when it stops. Due to the hysteresis and inertia of electromagnetic machinery, it is almost impossible to control the movement of the feed slide by 0.1 mm through “on” and “off”. In order to ensure the minimum feeding length and feeding accuracy, the rear tongs make the feeding slide back to LK position, then move forward to the predicted position LT, and close the feeding solenoid valve. When the feeding cylinder movement stops, the rear clamp is clamped.
Circular sawing machine
Circular saw machine, also known as circular saw machine, is divided into automatic and semi-automatic. The circular saw blade makes a rotary cutting motion, and at the same time, it makes feed motion with the saw blade box. According to the feed direction of saw blade, circular sawing machine can be divided into horizontal (horizontal feed), vertical (vertical feed) and pendulum (swing feed around a fulcrum). In addition, there are various kinds of special circular sawing machines, such as the moving head saw for cutting large casting risers, and the combined sawing and drilling machine for rail sawing and drilling.
Band sawing machine
The circular saw belt is tensioned on two saw wheels, and the saw wheel drives the saw belt to cut. There are two main types of band sawing machines: vertical and horizontal. The saw frame of vertical band sawing machine is set vertically, and the workpiece moves during cutting, which is used to cut the curve contour of sheet metal and forming parts. The saw band can also be replaced by file chain or abrasive belt for filing or grinding. The saw frame of horizontal band sawing machine is arranged horizontally or obliquely, feeding along the vertical direction or swinging direction around a fulcrum. The saw band is generally twisted by 40 ° to keep the saw tooth perpendicular to the workpiece. The horizontal type is divided into scissor type, double column type and single column type band sawing machine; according to the use situation, it can be divided into manual type (economical manual feeding, manual cutting material) and automatic type; according to the automatic program of the controller, it can be divided into manual type (semi-automatic manual feeding) and full-automatic (automatic feeding and automatic cutting)
Sawing machine
The saw bow equipped with saw blade makes reciprocating motion and feeds by swinging the saw frame around a fulcrum. The machine tool has the advantages of simple structure, small volume and low efficiency. There are two kinds of moving tracks of the saw blade of the sawing machine: straight line and arc. When the arc moves, the saw bow swings around a fulcrum with a small angle. The cutting amount of each saw tooth is large, the chip removal is easy, and the efficiency is high. This method is mostly used in the new type of sawing machine.
