Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0013] Such as figure 1 As shown, taking the outer contour milling of parts with Φ10 end milling cutter as an example, the length of the part is guaranteed to be 50±0.05mm, and the width is 30±0.10mm. The method to avoid mistakenly inputting the tool radius compensation value in NC machining includes the following steps:

[0014] Step 1: The machining center calculates the theoretical tool radius compensation value according to the size of the part to be processed;

[0015] When machining the outer contour of a part: The theoretical tool radius compensation value = the actual radius of the tool + half of the minimum lower deviation value in the contour size of the processed part, that is, the theoretical tool radius compensation value = 5-0.05 / 2 = 5-0.025 = 4.975mm;

[0016] Step 2: Manually input the tool radius compensation value;...

Abstract

The invention discloses a method for avoiding mistaken input of a tool radius compensation value during numerical control machining, and belongs to the field of numerical control machining. The method is mainly applied to machining in a numerical control outline programming mode. According to the method for avoiding mistaken input of the tool radius compensation value during numerical control machining, the phenomenon that due to the fact that a numerical control operator mistakenly inputs the tool radius compensation value, a part is excessively poor or scrapped is effectively avoided, the part delivery task is completed on time, and economic benefits are improved as well. The method comprises the following steps that firstly, a machining center calculates the theoretical tool radius compensation value according to the size of the part needing to be machined; secondly, the tool radius compensation value is manually input; thirdly, whether the manually-input tool radius compensation value is larger than or equal to the tool radius compensation value or not is judged, if the manually-input tool radius compensation value is larger than or equal to the tool radius compensation value, executing the step four, and if not, executing the step two; fourthly, the machining center machines the part according to the manually-input tool radius compensation value.

Description

technical field [0001] The invention belongs to the field of numerical control machining, and in particular relates to a method for avoiding mistakenly inputting tool radius compensation values ​​in numerical control machining, which is mainly applied to machining such as numerical control turning, numerical control milling, etc., which are carried out by means of numerical control contour programming. Background technique [0002] In CNC machining, according to different programming methods, it can be divided into two methods: contour programming and tool center path programming. Among them, contour programming refers to programming according to the contour shape of the part, and then the operator selects a suitable tool, manually enters the tool radius compensation value, and then performs NC machining. This programming method has certain advantages when the material of the part is hard or the machining allowance is large, rough machining and finishing machining are requir...
