introduction：The principle of induction cooker When a loop is fed a current，The effect is equivalent to a magnet bar。So the coil surface has a magnetic fieldN-SPole production，There is magnetic flux passing through。Suppose the power supply used is AC，Both the magnetic pole of the coil and the magnetic flux across the surface of the loop change。 When a magnetic conductive metal surface is placed above the loop coil，At this point, the metal surface will induce an electric current。Because theres resistance on the metal，Therefore, the induced current causes the metal surface to generate heat，And use this heat energy to cook food。 The greater the current induced, the higher the heat generated，The less time it takes to cook the food。To make

introduction：The transmission efficiency of reducer is measured by single direct power measurement method，According to the test principle，Make use ofCGQT type torque speed sensor measures the input of cycloidal pinwheel reducer、Output torque（Rotational speed），After computer processing and calculation，The efficiency of cycloidal pinwheel reducer is obtained。The result shows that：With no interference，The measured efficiency value is relatively stable，Almost unaffected by load changes and temperature changes。Suitable for cycloidal pin gear reducer、Measurement of transmission efficiency of gear reduction machinery such as helical gear reducer。 The internal transmission device of cycloidal pinwheel reducer can be divided into three parts：Input part、Retarding section、Output part。On input axis

introduction： MasterCAMProcessing parameters of various processing methods，Including the implementation of cutting parameters are set in the form of dialog box，Just fill it in when using。MasterCAMMetric system available in milling、British system two kinds of total6Individual tool library，Basic tools are included in the tool library，When setting machining parameters，After calling the tool in the tool library, the cutting parameters are automatically entered into the dialog box。However, in actual use, we found that the geometric parameters provided by the tool are the feed rate of each axis、Lifting speed、Spindle speed and other cutting parameters，It does not conform to the actual situation of the existing tools in the workshop,At the same time it does not reflect the workshop tool library
