This article systematically introduces the principles of tool selection in turning operations, focusing on the selection methods for external turning inserts.Through practical examples of different turning types, it helps readers master key application techniques.<\/p>\n
<\/p>\n
When selecting tools, clamping reliability and modular tool priority must be considered.During the turning process, ensuring secure clamping between the insert and tool holder is critical as it directly affects machining stability.<\/p>\n
The type of tool holder selected is influenced by the lead angle (entering angle), shape, and size of the insert being used.Meanwhile, corresponding tool holder systems should be chosen based on different operation types.Additionally, deciding between negative or positive rake angle inserts is an important consideration.To facilitate replacement and adjustment, modular tool options should be prioritized.<\/p>\n
Next, we will delve into the selection methods for external turning inserts. One of the four main application areas is longitudinal turning or face turning, which represents the most common type of turning operation.<\/p>\n
<\/p>\n
In longitudinal turning or face turning, diamond-shaped C-type inserts paired with appropriate lead angles constitute the most commonly implemented solution.<\/p>\n
<\/p>\n
In longitudinal turning or face turning, the diamond-shaped C-type (80\u00b0) insert is a commonly used option.<\/p>\n
The tool holder’s lead angle is typically set at 95\u00b0 and 93\u00b0 (entering angles of -5\u00b0 and -3\u00b0) to ensure optimal cutting performance.<\/p>\n
In addition to C-type inserts, D-type (55\u00b0), W-type (80\u00b0), and T-type (60\u00b0) inserts can serve as alternatives to accommodate different requirements.<\/p>\n
<\/p>\n
Selecting appropriate lead angles to ensure machining versatility and accessibility is crucial in contour turning.<\/p>\n
<\/p>\n
In contour turning processes, selecting an appropriate KAPR (entering angle) is crucial.<\/p>\n
Typically, a 93\u00b0 lead angle (corresponding to a -3\u00b0 entering angle) is most commonly used as it achieves an internal contour angle of 22\u00b0-27\u00b0, ensuring machining versatility and accessibility.<\/p>\n
D-type (55\u00b0) and V-type (35\u00b0) inserts serve as frequently used alternative options to meet different cutting requirements.<\/p>\n
<\/p>\n
Tools require radial feed movement with proper lead angle selection to ensure cutting stability and machining quality.<\/p>\n
In face turning, tools feed radially to complete workpiece machining.<\/p>\n
This turning method demands appropriate insert and lead angle selection to guarantee process stability and output quality.<\/p>\n
Common lead angles include 75\u00b0 and 95\u00b0\/91\u00b0, with corresponding entering angles of 15\u00b0 and -5\u00b0\/-1\u00b0 respectively, fulfilling diverse cutting needs.<\/p>\n
Additionally, C-type (80\u00b0) and S-type (90\u00b0) inserts are standard alternative choices.<\/p>\n
<\/p>\n
Implementing round inserts for shallow grooving to enhance production efficiency represents a key methodology in contour groove turning.<\/p>\n
<\/p>\n
An effective method for shallow grooving or groove widening operations.<\/p>\n
<\/p>\n
Round inserts demonstrate excellent performance in plunge turning, suitable for both radial and axial feed directions, significantly enhancing machining flexibility.<\/p>\n
The 90\u00b0 neutral holder design represents the most common round insert configuration, particularly favored in face turning applications.<\/p>\n

Large Lead Angle Advantages<\/p>\n
Effectively directs cutting forces<\/p>\n
Ideal for shoulder turning operations<\/p>\n
Note: Potential machining quality impacts constitute a distinctive characteristic of large lead angle designs.<\/p>\n
<\/p>\n
In face turning operations, the large lead angle (or small entering angle) design effectively directs cutting forces toward the chuck, enhancing machining stability.<\/p>\n
This configuration is suitable for shoulder turning, expanding processing capabilities.<\/p>\n
However, when machining superalloys and hard materials, groove wear may potentially affect machining quality.<\/p>\n
<\/p>\n
Concentrated cutting forces adapt well to multiple working conditions<\/p>\n
Note: The core advantage of small lead angle design lies in mitigating groove wear concerns<\/p>\n
<\/p>\n
The small lead angle design (i.e., large entering angle) offers the following benefits in practical applications:<\/p>\n
Concentrated cutting forces facilitate stable chuck control<\/p>\n
Thinner chip thickness during machining helps improve productivity<\/p>\n
Reduced groove wear extends tool life<\/p>\n
<\/p>\n
Proper selection ensures machining strength and tool longevity. The influence on cutting force distribution is a key factor in contour angle selection.<\/p>\n
