Training CAM operators and skill enhancement! What are the five key points for successfully performing long hours of finishing work?

In the finishing of product surfaces and design surfaces of mold parts, a high number of processes can easily lead to "machining steps." Therefore, to achieve a good finish, it is necessary to perform finishing operations with as few tools as possible. As a result, the initial finishing process that shapes the entire form often involves using a small-diameter tool for extended periods. 【 Five Important Points for Finishing Operations 】 ◇ Regarding Tool Selection 1. Precision of Ball End Mill Tip... Stable R precision over 180° 2. Tool Rigidity... Use a strong pencil neck when the protrusion is long 3. Coating Characteristics... Important to suppress chip welding and ensure lubrication ◇ Regarding Machining Methods and Cutting Conditions 4. Semi-finishing... Do not leave large bumps or excess material after roughing 5. Cutting Conditions... Set the rotation speed low to avoid sudden changes For more details, please refer to the PDF document. If you have any questions, please feel free to contact us.

What are the key points for solving the 'processing step' that is likely to occur in product finishing? We are currently offering materials such as "Case Studies on Troubleshooting in Mold Processing"!

In finishing processes, if there are many leftover steps and a large number of tools are used, thermal displacement of each axis and the main spindle of the machine can easily cause "machining steps" on the finished surface. Therefore, to reduce or eliminate machining steps, it is essential to minimize the types and number of tools used during the finishing process. 【Five Important Points in Finishing Processes】 ◇ Tool Selection 1. Use tools with good cutting performance and edge accuracy (no variation in R accuracy or outer diameter). 2. Use tools with low deflection and high rigidity (use a pencil neck when the protrusion is long). 3. Use tools with coatings suitable for the work material (especially for soft steel). ◇ Machining Methods and Cutting Conditions 1. Ensure that roughing before finishing does not leave any material in corners or recesses. 2. In semi-finishing, process the entire area to a uniform finishing allowance (do not leave large bumps). 3. In finishing, avoid high-speed rotation to minimize the expansion and contraction of the machine spindle. 4. Use cutting fluid to improve chip removal and lubrication of the cutting edge.

To improve the precision of NC machining, "control of tool deflection and bending" is crucial! What kind of problems are occurring in actual machining sites?

The left image shows a case where "gouging" occurred on a ribbed wall shape, which is an example of a machining problem. The cause was that "the tool tip bent significantly due to cutting resistance" during rough machining. In contour path machining, when entering a solid ribbed shape, the tool tip experiences the greatest cutting resistance. However, if the groove width is narrow, the tool tip may bend and gouge into the wall. The amount of tool deflection varies significantly not only with the magnitude of cutting resistance but also with the tool's overhang length. If the overhang length doubles, the deflection increases by a factor of eight, proportional to the cube. Additionally, the deflection amount also changes with the tool diameter. It is inversely proportional to the fourth power, so the deflection of a tool with a diameter of Φ8 is about 2.4 times that of a tool with a diameter of Φ10 (assuming the same overhang length). Therefore, when machining with small diameter tools (Φ4 or less), using pencil neck tools and considering "rigidity in tool selection" is particularly important for stable cutting operations.

To suppress tool deflection, it is important to consider "tool selection based on rigidity"! Technical materials that are helpful for training CAM operators are currently available!

To improve the accuracy of NC machining, controlling "tool deflection" is essential. However, issues such as tool engagement occurring at the vertical walls, corners, and recesses of rib grooves (see image) can lead to machining troubles. To achieve direct engraving without causing these problems, there are three important points to consider: 1. During roughing of rib groove shapes, keep the deflection of the cutting edge below the finishing allowance. 2. To reduce the deflection of the cutting edge, minimize the cutting resistance acting on it. 3. Increase tool rigidity within permissible limits concerning the height of the machining shape and the slope angle of the vertical walls. Therefore, to perform stable cutting operations with small-diameter tools of Φ4 or less, selecting "sturdy" tools, such as pencil neck tools, becomes particularly important.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If you require a detailed technical explanation, please contact us.
