Parallel kinematics is a branch of mechanics that focusses on manipulators formed by closed kinematic chains, i.e., mechanisms that have an endeffector joined to the fixed frame by several limbs. Parallel Kinematics for Machine Tools SpringerLink
Since its introduction in the middle 90s, parallel kinematics machine tools (PKMT) created high expectations through their possible roles in industry. More than twenty years have gone since then (1994), and even though these kinematic structures have provided excellent performance regarding dynamic capacity, stability, precision, and rigidity
Parallel kinematic machines (PKMs) have been attracting attention in research institutes as well as in the machine tool industry because of their structural rigidity due to their closed kinematic loops and their conceptual capabilities in high dimensional accuracy.
Compared to a conventional serial kinematic machine tool, a parallel kinematic machine tool has advantages for high speed and multi-degrees of freedom positioning.
rigidity and high dynamic capacities. Indeed, the parallel kinematic arrangement of the links provides higher stiffness and lower moving masses that reduce inertia effects. Thus, PKMs have better dynamic performances. However, the design of a parallel kinematic machine tool (PKMT) is a hard task that requires further research studies before wide
As a result, prototypes of a new class of machine tools based on parallel kinematic structures, known as parallel kinematic machines (PKMs), have been introduced. The six degree-of-freedom Stewart platform [1] is one PKM configuration that has been used recently in a number of new machine tool designs. A Stewart platform machine tool typically

Today, parallel kinematic machine tools, slowly but surely, entering the commercial market and are already established in niche applications [14, 13, 20]. CLASSIFICATION OF PARALLEL KINEMATICS MACHINES A parallel manipulator is a closed‐loop mechanism in
Parallel Kinematics Machining (PKM) is considered the biggest breakthrough in machining technology since the invention of CNC machine tool. With PKM’s unique freedom of axis movements and 360 degree rotating cutting head, you can mill, drill tap, rough, and finish all sides (left, right, top, down, front, rear) of part in 1 setup.
The system includes kinematic/dynamic analysis, kinetostatic model, CAD module, FEM module, CAM module, optimization module and visual environment for simulation and collision detection of the machining and deburring. It is an integration of the parallel kinematic machines (PKM) design, analysis, optimization and simulation.
A conventional wrist is additionally mounted on the mobile platform. This resembles another device, the parallel kinematic machine (PKM), which is a machine tool with a spindle. The result of the parallel design is a robot that has increased stability and arm rigidity,
Based on Exechon's parallel kinematics processing technology, advanced 5-axis control, we manufacture and sell parallel link modules. GKM CO., LTD. was born out of BBS Kinmei, that is pursuing processing technology and precision of M achine, which realizes automation and labor saving of production lines of all industries.
We propose a technique to measure position-independent geometric errors (PIGEs) in the rotary and spindle axes of a hybrid parallel kinematic machine (PKM). The PKM investigated here includes one more rotary axis than an Exechon PKM, which is used to improve the productivity of hybrid processes, such as machining and direct-energy-deposition three-dimensional metal printing.
Existing machine tools with parallel kinematics permit higher supply speeds and accelerations, but cannot match the rigidity of classical designs. For designs with parallel kinematics, the rigidity is 5– 200 N/μm, depending on the structural features [4, 5].
Also receiving discussion is the design of mechanism systems such as kinematic analysis, stiffness analysis, kinetostatic modeling, and optimization. Author Dan Zhang uses his years of experience in the field to also: Cover the latest material in parallel kinematic machine tools and the junction of parallel robot and machine tools.
