The application of Xindashida motion control systems in woodworking engraving machines in the machine tool industry.
Project Background
A wood carving machine is a type of mechanical engraving machine used for decorating furniture, the musical instrument industry, wooden handicrafts, large-area flat surface engraving on boards, solid-wood furniture, solid-wood artistic murals, cabinet and door/window carvings, screen panel engravings, and more. The wood carving machine consists of three main components: a computer, a wood carving machine controller, and the machine’s main body. Operating principle: Specialized engraving software installed on the computer converts graphic files into signals that can control the movements of the machining equipment. These signals are then transmitted to the wood carving machine controller, which in turn translates them into signals (position command pulse trains) capable of driving the motors, thereby controlling the movement paths of the machine’s axes. Meanwhile, the high-speed rotating carving head (spindle) mounted on the machine uses cutting tools to carve the workpiece fixed on the worktable, enabling the creation of various two-dimensional or three-dimensional relief graphics and text designed on the computer, thus achieving automated engraving operations. The advent of wood carving machines has made it possible for the entire process—from initial sketching to final finishing—to be completed automatically by the machine itself, significantly reducing the time required for carving. Multi-head wood carving machines can even process multiple pieces of wood simultaneously, further minimizing manual labor and greatly improving work efficiency.
Customer needs
Requires faster response speed, precise positioning, short setting time, and clear engraving shapes.
Xinshida Solution
Scheme advantages
The servo drive operates in position mode. The host computer sends position commands to the servo drive via a pulse control card, and the servo drive then drives the motor to operate according to the given command signals.
Relevant parameter settings:
The position, velocity, current, and other parameters can be monitored via the host computer, allowing users to accurately observe the waveforms of both the command signals and feedback signals, thus facilitating debugging and application.
• Speed gain adjustment
For commands received from the higher-level system, the driver must actuate the motor as promptly and accurately as possible in accordance with these commands. To make the motor’s response more closely match the commands, gain adjustments are performed.
• Electronic gear ratio setting
Taking the Z-axis as an example, after manually moving upward to a target value of 10 cm, use a tape measure to determine the actual value. The reciprocal of the ratio between the target value and the actual value is the electronic gear ratio.
• Position gain adjustment
Under normal circumstances, the default position-loop gain is sufficient to meet the requirements of the engraving machine. If the engraving quality is not smooth, you can add filtering to the position command.
Scheme Composition
The system consists of four sets of dual-axis servo drives and servo motors, plus one machine frame, eight sets of spindle frequency converters and motors, and a computer control system.
Functions of each axis:
X and Y axes: horizontal linear motion, with the motor directly connected to the lead screw;
Z-axis: Vertical motion; the motor with brake is directly connected to the lead screw.
Axis A: Eight reducers are connected in series to drive the wood in rotational motion. After finishing machining one surface, the workpiece is flipped over to the other surface for continued processing. Combined with the other three axes, this setup enables three-dimensional machining.

Project Results
The Xinshida Ω6-W series servo supports dual-axis drive and can accommodate absolute encoders with up to 23 bits. It features multiple built-in bus interfaces and boasts advantages such as high-speed response, precise positioning, short settling time, and smooth operation. During high-speed machining, the entire machine virtually eliminates vibration; after machining is complete, there are no burrs or tool marks, and the carved shapes are clear and accurate—earning high praise from customers who use wood carving machines.
The figure below shows the finished product machined using the Xindashida Ω6-W series servo.
