Aqueous compositions, aqueous cutting fluid using the same, method for preparation thereof, and cutting method using the cutting fluid

An aqueous cutting fluid which can reduce the impact on working environment and the global environment, and can achieve both preventing precipitates from becoming a hard cake and keeping high dispersibility for abrasive grains is provided. Such an aqueous cutting fluid is obtained by a method comprising dispersing abrasive grains (G) in an aqueous composition comprising a dispersion medium (M) containing a hydrophilic alcohol compound such as ethylene glycol, a lipophilic alcohol compound such as propylene glycol and water, and silica colloid particles dispersed stably in the medium. The dispersion medium (M) is odorless and not flammable. The abrasive grains (G) may settle out after a time, but they do not closely contact with one another, and therefore the resulting precipitates do not become a hard cake, which allows the re-dispersion and reuse of precipitated grains. The instant aqueous cutting fluid is inherently low viscous, and the reduction of viscosity owing to the contamination of water and the increase of viscosity owing to contamination of shavings are both moderate. As a result, the cutting fluid has a long life. And articles which have been cut using the cutting fluid can be washed with water. Further, as the dispersion medium (M) is a biodegradable low molecular weight organic compound, a waste liquid from a process using the cutting fluid can be disposed with an activated sludge.

Path planning Q-learning initial method of mobile robot

The invention discloses a reinforcing learning initial method of a mobile robot based on an artificial potential field and relates to a path planning Q-learning initial method of the mobile robot. The working environment of the robot is virtualized to an artificial potential field. The potential values of all the states are confirmed by utilizing priori knowledge, so that the potential value of an obstacle area is zero, and a target point has the biggest potential value of the whole field; and at the moment, the potential value of each state of the artificial potential field stands for the biggest cumulative return obtained by following the best strategy of the corresponding state. Then a Q initial value is defined to the sum of the instant return of the current state and the maximum equivalent cumulative return of the following state. Known environmental information is mapped to a Q function initial value by the artificial potential field so as to integrate the priori knowledge into a learning system of the robot, so that the learning ability of the robot is improved in the reinforcing learning initial stage. Compared with the traditional Q-learning algorithm, the reinforcing learning initial method can efficiently improve the learning efficiency in the initial stage and speed up the algorithm convergence speed, and the algorithm convergence process is more stable.
