Machining Accuracy of Machine Tools
Technical Information Machining Accuracy of Machine Tools Productivity and accuracy of machine tools are important competition aspects. Rapidly changing operating conditions for machine tools, however, make it diffi cult to increase productivity and accuracy. In the manufacture of parts, increasingly small batch sizes have to be produced economically, and yet accurately. In the aerospace industry, maximum cutting capacity is needed for the roughing processes, whereas the subsequent fi nishing processes must be executed with maximum precision. For milling high-quality molds, high material removal rates are required during roughing and excellent surface quality must be obtained after fi nishing. At the same time, maximum contouring feed rates are necessary to realize the required minimum distances between the paths within acceptable machining times. Thermal accuracy of machine tools is becoming increasingly important considering the strongly varying operating conditions in manufacturing. Especially with small production batches that require constantly changing machining tasks, a thermally stable condition cannot be reached. At the same time, the accuracy of the fi rst workpiece is becoming very important for the profi tability of production orders. Constant changes between drilling, roughing and fi nishing operations contribute to the fl uctuations in the thermal condition of a machine tool. During the roughing operations, the milling rates increase to values above 80 %, whereas values below 10 % are reached during fi nishing operations. The increasingly high accelerations and feed rates cause heating of the recirculating ball screw in linear feed drives. Position measurement in the feed drives therefore plays a central role in stabilizing the thermal behavior of machine tools. -
Introduction to Selecting Milling Tools Iimportant Decisions for the Selection of Cutting Tools for Standard Milling Operations
Introduction to Selecting Milling Tools IImportant decisions for the selection of cutting tools for standard milling operations The variety of shapes and materials machined on modern milling machines makes it impera- tive for machine operators to understand the decision-making process for selecting suitable cutting tools for each job. This course curriculum contains 16-hours of material for instructors to get their students ready to make basic decisions about which tools are suitable for standard milling operations. ©2016 MachiningCloud, Inc.

Lapping Plate
Lapping Plate 05M20.20 Patent Pending Lapping is the process of rubbing two surfaces together with an abrasive and a lubricant to improve the quality of at least one of the surfaces. Although lapping can be used to create fl at surfaces, in the context of woodworking, lapping better serves to minimize the roughness of a surface – known as surface conditioning. By minimizing the roughness in the sole of a plane, there is reduced friction between the plane and the workpiece, which in turn reduces abrasion. For blades or chisels, the cutting edge can be made sharper if both intersecting surfaces are free of scratches, even if the back of the blade isn’t perfectly fl at. Straight cutting edge on a lapped blade. Jagged cutting edge on a ground blade. Figure 1: A ground blade versus a lapped blade. Lapping can remove only small amounts of material. If the sole of your plane or the back of your blade is twisted, wavy or bowed, it will be necessary to sand or grind off the high points prior to lapping. Lapping is always performed with an abrasive oil slurry, which not only allows the object to slide Small Abrasive about the lapping plate (called a lap), but also Particles provides a means to remove abraded particles and worn abrasive. Oil Object Abraded Metal Lap Groove in Lap Large Abrasive Particles Figure 2: Lapping mechanics. 2 Important Notes The lapping plate is made of soft iron and will wear over time. These instructions provide information on how to ensure the lap remains fl at for a lifetime. -

Appendix D – Machining Guidelines
Appendix D – Machining Guidelines A. Holding and Chucking When holding any composite billet or part it is important to remember that, unlike metallic materials, polymers will deform/distort under excessive holding pressures. This is very important when machining parts/billets with a thin cross-section (0.250 in / 6.35 mm or under) and for finish machining. Parts/billets that are held too tightly may spring back after release from the holding mechanism and result in parts that are not concentric and/or undesirable dimensions. 1. Standard Jaw Chucking Four or six jaw chucks are acceptable for thick cross-section parts and billets. Ensure medium chucking jaw pressure to prevent material distortion. 2. Pie Jaw Chucking Pie jaw chucking, contacting as close to 90% of the OD as possible, is a superior holding method over standard jaw chucking. This works well for any operation and is preferred over standard chucking for finish machine operations. 3. Adhesive Bonding / Gluing As an alternate to standard chucking directly to the composite, a billet can be glued to a fixture of alternate material prior to machining operations. If this method is used, it is recommended that guidelines from the adhesive manufacturer be followed to ensure sufficient quantity and coverage. Both Loctite® 4090 and 3MTM Scotch-WeldTM Acrylic Adhesive 8405NS have been successfully used. 4. Holding Fixtures Use holding fixtures to grip composite components during finish machining operations. Holding fixtures shall contact 100%of either the OD or ID and should be a snug fit (in/out by hand). PTFE is the best material of construction for fixtures with PVC being a close (slightly more rigid) second choice. -
