4 Technical Information for Special features thread A thread on the external surface of a cylinder screw or cone epth of thread The distance between the crest and root measured from normal to theaxis The distance between the corresponding points on adjacent thread forms measured parallel to the axis. This distance can be defined in millimeters or by the tpi (threads per inch), which is the reciprocal of the pitch Root Crest thread Major Ø Ø Minor Ø Thread Angle Helix Angle Major diameter The largest diameter of a screw thread diameter On a straight thread, the diameter of an imaginary cylinder, the surface of which cuts the thread forms where the width of the thread and groove are equal Minor diameter The smallest diameter of a screw thread Helix angle For a straight thread, where the lead of the thread and the pitch diameter circle circumference form a right angled triangle, the helix angle is the angle opposite of the lead Nominal diameter The diameter of which the diameter limits are derived by the application of deviation allowances and tolerances thread A thread on the internal surface of a cylinder or cone Straight thread A thread formed on a cylinder Taper thread A thread formed on a cone Left handed thread Right handed thread The helix angle Helix angle Lead (L) A thread which, when viewed axially, winds in a counter clockwise and receding direction. All left handed threads are designated LH A thread which, when viewed axially, winds in a clockwise and receding direction. Threads are always right handed unless they are specified X diamiter () For a straight thread, where the lead of the thread and the pitch diameter circle circumference form a right angled triangle, the helix angle is the angle opposite of the lead Machining a multi-start thread A thread in which the lead is an integral multiple, greater than one, of the pitch. A multi-start thread permits a more rapid advance without a coarser (larger) thread form First start machined Second start machined Third start machined (Final, 3 starts thread) Insert profile style Partial profile Full profile Full profile for fine pitches Semifull The V partial profile insert cuts without topping the outer diameter of the thread. The same insert can be used for a range of different thread pitches which have a common thread angle The full profile insert will form a complete thread profile including the crest. For every thread pitch and standard, a separate insert is required The full profile for Fine es will form a complete thread The topping of the outer diameter is generated by second tooth The Semi profile insert will form a complete thread including crest radius but without topping the outer diameter Mainly used for trapezoidal profiles 3

6 Technical Information for Thread infeed method Infeed Radial infeed Flank infeed (modified) Alternate flank infeed When the pitch is smaller than 16 tpi For material with short chips For work with hardened material When the thread pitch is greater than 16 tpi. Using the radial method,the effective cutting edge length is too large, resulting in chatter. for TRAPEZ and ACME. The radial method results in three cutting edges, making chip flow very difficult This method divides the load equally on both flanks, resulting in equal wear along the cutting edges Alternate flank infeed requires more complicated programming, and is not available on all lathes Application Radial infeed is the simplest and quickest method The feed is perpendicular to the turning axis, and both flanks of the insert perform the cutting operation Radial infeed is recommended in 3 cases Flank infeed is recommended in the following cases Use of the alternate flank method is recommended especially in large pitches and for materials with long chips Shim Standard shim ATE () ATI (Through) Helix angle 1.5 Insert size Holder d L Ordering code ER(L)H IR(L)H ATE16 ATI ER(L)H ATE22 IR(L)H ATI ER(L)H IR(L)H ATE27 ATI27 Standard shim has lead angle 1.5 Application grade Grade Features Available insert type PC5300 Universal grade For chip breaker type only Stable machining on a wide application due to fine-grained carbide substrate with balanced heat resistance and toughness Excellent wear resistance and oxidation resistance due to AiTN coating film Outstanding performance on high speed machining ERM/IRM (Insert with Chip breaker) Specialized grade for threading inserts A tough sub-micron substrate with TiAlN coating provides good fracture toughness and excellent wear resistance Outstanding performance on STS and hard to cut materials ER/IR (Ground insert) PC9070 Specialized grade for threading inserts Strong wear resistance in stainless machining thanks to multilayer PV coatings ER/IR (Ground insert) Recommended cutting speed as per workpiece (vc) Workpiece P Carbon steel, Alloy steel, Cast Steel PC5300 M Stainless steel, Heat resistant steel, Titanium alloy steel PC5300 PC9070 K Carbon Iron, Aluminum, Cast Steel, Copper PC5300 5

This helical motion combines circular movement in one plane with a simultaneous linear motion in a plane perpendicular to the first. For example, the path from point A to point B (Fig,A) on the envelope of the cylinder combines a circular movement in the x-y plane with a linear displacement in the z direction On most CNC systems this function can be executed in two different ways: - GO2: Helical interpolation in a clockwise direction - GO3: Helical interpolation in a counter-clockwise direction Fig. A Fig. B The thread milling operation (Fig. B) consists of circular rotation of fhe tool around its own axis togerther with an orbiting motion along the bore or workpiece circumference. uring one such orbit, the tool will shift vertically one pitch length. These movements combined with the insert geometry create the required thread form. There are three acceptable ways of approaching the workpiece with the tool to initiate production of the thread: 1. Tangential Arc Approach 2. Radial Approach 3. Tangential Line Approach 40

42 Technical Information for Thread Milling Tangential arc approach With this method, the tool enters and exits the workpiece smoothly. No marks are left on the workpiece and there is no vibration, even with harder materials. Although it requires slightly more complex programming than the radial approach (see below), this is the method recommended for machining the highest quality threads thread thread 1-2: rapid approach 2-3: tool entry along tangential arc, with simultaneous feed along z-axis 3-4: helical movement during one full orbit (360 ) 4-5: tool exit along tangential arc, with continuing feed along z-axis 5-6: rapid return Radial approach This is the simplest method. There are two characteristics worth nothing about the radial approach: A. a small vertical mark may be lift at the entry (and exit) point. This is of no significance to the thread itself B. when using this method with very hard materials, there may be a tendency of the tool to vibrate as it approaches the full cutting depth Note: Radial feed during entry to the full profile depth should only be 1/3 of the subsequent circular feed thread thread 1-2: radial entry 2-3: helical movement during one full orbit (360 ) 3-4: radial exit Tangential line approach This method is very simple, and has all of the advantages of the tangential arc method However, it is applicable only with external threads thread 1-2: radial entry with simultaneous feed along z axis 2-3: helical movement during one full orbit (360 ) 3-4: radial exit 41
