The Techno motion controller is primarily a standalone type that does not require a PC. For example, the one-board motion controller (SLM8000) can be used as an NC simply by powering on the main unit (board). This means it can be used with processing machines even without a PC. However, for instance, the data output from CAD/CAM may be expected to be large in size. ======= If we consider the command time for one instruction (linear interpolation) to be 0.1 seconds and the processing time to be 10 hours (36,000 seconds), the number of commands would be 360,000. Assuming one command is 64 bytes, the operating program would be approximately 22 MB. ======= In such cases, it is not possible to store all G-code programs in the memory of the motion controller. Therefore, DNC is used.

"Multi-head assembly machines linked on a circular table" and "sheet winding" require multi-axis synchronous control. Traditionally, synchronization was achieved through mechanical cams and linkage mechanisms, but there are increasing examples of replacing this with servo and electronic cam control. The electronic cam method offers various advantages compared to the mechanical cam method. However, to truly benefit from these advantages, it largely depends on the functions and performance of the motion controllers and servos. In specialized electronic component manufacturing, there may be cases where precise repetitive motion is required at high tact rates of several tens of milliseconds. Additionally, there are multi-axis synchronous systems with nearly 100 axes. At Fine Motion, we can achieve the industry's fastest synchronous control and ultra-multi-axis synchronization with a combination of general-purpose servos. For more details, please contact us.

• Assembly Machine

In automated production lines, efficient transportation and stocking of workpieces (products) between stations such as assembly, processing, and inspection is an important theme. As the demand for fine, high-density, and high-speed transportation increases, not only simple positioning but also precise trajectory control becomes necessary. Additionally, due to the limitations of the mechanism's rigidity and the mass and inertia of moving parts, it is essential to achieve the highest speed and high precision through optimal acceleration and deceleration control for smooth operation. There are many combinations with image processing for work inspection and alignment, and further integration of assembly, implementation, transportation, processing, and inspection within the same system is progressing. Fine Motion realizes a high-value precision transportation system characterized by "precise motion," "multi-task processing," "flexible customization," and "real-time linkage between PC and PLC."

Winding requires very high precision. Fine wires are aligned and wound, but if the traverse pitch (the feed amount per rotation) does not match the winding diameter, gaps or lumps can occur. Furthermore, once misalignment happens during the winding process, the product cannot be completed. Additionally, since the unit cost of winding is low, it is necessary to increase productivity by winding at high speeds. [Challenges] - I want to easily program winding commands. By parameterizing the traverse width, pitch, total number of turns, spindle rotation speed (for low-speed and high-speed layers), spindle acceleration and deceleration, and timing corrections for reversals, I want to easily program the winding operation. Example: Error in bobbin shape: fine-tune the traverse width Change in wire diameter: fine-tune the pitch - I want to achieve sufficient winding precision. - I also want to easily perform tasks like soldering and cutting.

• Software (middle, driver, security, etc.)

High-precision latches are used for automatic measurement of tool lengths, shape inspection (measurement) with touch probes, and three-dimensional (3D) shape inspection (measurement). Touch probes (which detect contact with a special sensor) are attached to a multi-axis drive mechanism (head) and brought into contact with the workpiece being measured. At that time, the sensor input latches the feedback counter coordinates (stores them in hardware) to measure the positional information. For example, when considering a machine tool for metal processing, it enhances machining accuracy by inspecting the displacement of the metal workpiece when it is positioned and by inspecting the shape of the metal workpiece. When inspecting with a camera, it is often the case that the required precision is not achieved due to light reflections; however, with mechanical sensors and high-precision latches, consistent and high-precision inspection (measurement) is possible as they are not affected by external disturbances such as light.

High-precision contour control is required for laser processing, high-precision transport, coating, cutting, and precision mounting. However, when turning corners at high speeds, inner trajectory errors occur due to delays in the servo system. By adjusting the speed at corners where there are significant changes in velocity and limiting the resulting acceleration during pre-interpolation acceleration and deceleration, we minimize the inner trajectory and the reduction of arcs. For more details, please contact us.

Tool diameter compensation is an effective function for laser processing and milling (end mill) processing. Although the operating program is created with the finished shape (as it is easier to visualize and simpler), it functions by having the tool path go outside the finished shape by the radius of the laser spot or tool.

In multi-axis interpolation, the delay in the servo system causes an inward deviation of the trajectory. As a result, there is a discrepancy between the actual trajectory and the ideal trajectory. The shape correction function compensates for the delay in the servo system, improving trajectory accuracy. This is effective for devices that require high speed and high precision, such as mold processing, polishing, and shaping. Additionally, the logging tool "TPC Logging" allows for the extraction of CSV data, enabling quantitative analysis of trajectory accuracy using Excel. For more details, please contact us.

In cutting shapes with cutters such as fabric, sheets, or boards, it is necessary to always orient the blade tip in the tangential direction of the shape trajectory (the direction of the cutter's movement). If the direction of the tangential line and the orientation of the blade tip differ, the blade may break. The axis that rotates the cutting tool (θ-axis) should constantly manage the direction of the XY vector and rotate automatically. Additionally, at corners, it is necessary to temporarily raise the blade tip, align the θ-axis with the next movement direction, and then lower the blade. In other words, the blade tip must always be controlled in the tangential direction. For more details, please contact us.

Here are some representative measurement examples using actual machines. It is a precision multi-axis machine controlled at a 10nm level. The reduction of the radius in normal arc interpolation is improved by a high position loop gain and pre-interpolation acceleration/deceleration. Furthermore, in high-precision arcs, quadrant protrusions also become an issue, but this is improved by linear motors. Measurement of roundness accuracy can be easily performed using Techno's motion controller tool, TPC logging, and analysis software such as Excel. Various tests can be conducted in a short time by changing the operating and control conditions. For more details, please contact us.

The techno motion controller allows for high-precision trajectory and speed control in interpolation and synchronous operations. The accuracy is about 1 pulse. If we assume the pulse unit is nm, the command error would be 1 nm. While there are error factors in the actual operation, including the entire servo system comprising the servo amplifier, motor, encoder, and mechanism, the motion controller on the command side can control very accurately and smoothly. The accuracy analysis function (TPC logging) can also be used for easy evaluation and verification. Here, we will introduce examples of "accuracy verification of linear interpolation trajectory and speed" and "torque measurement." For more details, please contact us.

With the increase in size and precision of stages, a gantry structure and parallel axis drive mechanisms are becoming necessary. If the table is driven from the center when operating the mechanism, the resistance in the driving direction will occur evenly on both sides. In contrast, if one side is driven due to the mechanism's configuration, twisting (yawing) of the table will inevitably occur. This yawing will lead to inaccuracies in the position of the workpiece on the table. Additionally, there may be cases where central driving is simply not possible due to the table being very large or structural constraints. In such cases, the key point is how to drive the table without yawing. A useful feature in such situations is the "Same Command Dual Axis" function. For more details, please contact us.

Continuous path motion is a fundamental performance requirement for motion controllers, and in precision motion control, it is a crucial point that can be considered its essence. It can be rephrased as the accurate continuity of multi-axis interpolation. Accurate continuous interpolation means "no positional error; the trajectory is precise" and "no velocity error; the speed and time are as specified." Fine and high-precision movements consist of a series of very small vectors. In processes such as machining, polishing, and winding, it is necessary to accurately maintain a large number of small interpolations continuously. The operation (processing) time T for one interpolation is determined by the feed speed F and the interpolation length L, where T = L/F. There is a limit to how small this time can be, beyond which the motion controller's control cannot keep up. This is why the minimum time for accurately continuous processing of small interpolations serves as a performance indicator for motion controllers. Techno's motion controllers can achieve continuous interpolation with a control cycle as short as 125 μsec. Accurate speed and smooth continuity are directly linked to the precision of operations and processing, significantly impacting work quality. For more details, please contact us.
