查询词典 tool point

To avoid loss of drilling tools and even well abandonment due to downhole fire or explosion during air drilling in pay zones, we developed a novel downhole fire or explosion prevention sub, a kind of downhole tool made of low melting-point alloy, designed to shield off oxygen so as to put out fires. This sub is connected to the upper part of dill bit.

为了解决空气钻井在钻遇油气层时，发生井下燃爆，造成埋钻具、井眼报废等复杂情况，基于阻断氧气使火熄灭的思路研制出了一种低熔点合金制造的井下工具－空气钻井燃爆灭火阀。

We propose a method for generating tool path s during three-axis NC machining of free surfaces using ball-end milling directly from measured discrete data point cloud.

提出了一种直接从测量的散乱数据点云用球头刀对自由曲面进行三轴数控加工时生成刀具路径的方法。

On the basis of summarizing and discussing the gamma inversion, we point out that an analytic method of volume attribute is very important. The method integrates multiple stepwise regression and cross verification to optimize and combine the attribute, adopts the convolution factor to eliminate frequency difference between the seismic and logging data, uses the neural network as a matching and predicting tool. Because of its religious theoretic base, the method is more accurate than other ones.

在对目前常用的伽玛反演方法进行总结、讨论的基础上，指出地震体属性分析法具有明确的物理意义，有效结合了多元逐步回归和交互验证法进行属性的优选和组合，采用褶积因子消除地震信息和测井信息的频率差异，并以神经网络为拟合和预测手段，具有严谨的理论基础，相比其它几种方法更为准确合理。

Meanwhile, a new approach is also proposed to increase the machining accuracy by using virtual knife tool center point together with a technique of robot system error pre-compensation.

同时，提出一种使用虚拟刀具工具中心点和预补偿机器人系统误差的方法，提高了机器人的加工精度。

While this exercise can be done on a thick length of chain, a tightrope, or even a two-by-four suspended on a pair of sawhorses, the ideal tool is a standard gymnastic balance beam. Stand on the beam on the ball of one foot, lifting the other leg and using it and your arms to find a balance point.
