This article provides a structured overview of commonly used CNC lathe G-codes, covering positioning, interpolation, threading, compensation, coordinate systems, and fixed machining cycles.
Ultra-thin-walled metal component machining serves as a key indicator of precision manufacturing capability. While current internationally leading roll forming processes can produce “tearable steel” sheets as thin as 0.03mm, they face limitations such as limited processing versatility and high equipment dependency.
When performing CNC programming, the programmer must determine the cutting parameters for each machining operation and incorporate them into the program as instructions.
Mold elbow joints are critical connecting components in injection molds, widely used in the injection molding industry. These joints feature complex structures, typically composed of multiple curved pipes, designed to connect different components or systems for fluid transmission or control functions.
Laser welding, with its advantages of high energy density and minimal heat-affected zone, is widely applied to components such as car doors and frames. However, defects like porosity and cracks frequently occur during actual production, compromising joint strength and driving safety.
Gears, as vital transmission components, find extensive application across the entire mechanical field. With technological advancements, increasing rotational speeds and load capacities have heightened the importance of operational smoothness, while simultaneously imposing stricter structural requirements on gears.
In machining, the tooling equipment used to secure workpieces in precise positions for processing or inspection is called machine tool fixtures. These fixtures effectively ensure machining accuracy, enhance work efficiency and quality, and broaden the application scope of machine tools.
Lightweighting is a key characteristic of products in aerospace and defense applications. As a heat-treatable, high-strength aluminum alloy with excellent toughness and hardness in the Al-Zn-Mg-Cu series, 7075 aluminum alloy is widely used for thin-walled components.
The complex external shape and internal structure feature numerous undercut surfaces, requiring multi-angle conversion for comprehensive machining. Existing three-axis or four-axis equipment struggles to accomplish this task. Even with custom fixtures, multiple setups result in low overall efficiency and subpar machining quality.
Turning-milling composite machines integrate dual turning and milling capabilities, enabling the completion of all or most machining processes on a single machine.
With the continuous advancement of aerospace product development and the leap in performance requirements, a large number of complex monolithic aluminum alloy structural components are being widely adopted in next-generation aerospace products.
