Problems solved by technology

However, in chamfering, there is a problem that in most cases it is enough to remove the corners, so there are few cases where precise precision is required, and even if a high-precision calculation result is obtained through an expensive dedicated system, it is impossible. Make full use of the results of operations rather than being efficient

Embodiment approach 1

[0034] figure 1 It is a block diagram of the automatic programming device in Embodiment 1 of this invention. The automatic programming device generates control instruction data based on the processing unit data for partial processing of the shape of the raw material. For the processing unit data for partial processing, the input processing unit data is analyzed to generate control command data for operating the machine tool. exist figure 1 Among them, the automatic programming device includes a raw material shape data input unit 1 , a processing unit data input unit 2 , a machining program storage unit 3 , a processing area shape generation unit 8 , and a control instruction generation unit 10 .

[0035] The material shape data input unit 1 inputs data defining the shape of the material from the outside, and stores the data in the machining program storage unit 3 . Taking a hollow cylindrical material shape as an example, the diameter of the cylindrical surface of the outer...

Embodiment approach 2

[0132] Figure 23 It is an explanatory diagram of a cross-sectional plane defined in the second embodiment. In Embodiment 1, the chamfering machining toolpath generation was assumed to be 5-axis machining, but it is also possible to approximate the toolpath by applying it to 3-axis machining. However, in the case of 3-axis machining, unlike the case of 5-axis machining, the tool posture is constant, so there are some differences in the processing related to the cross-sectional plane Fij. Points different from Embodiment 1 will be described below.

[0133] Such as Figure 23 As shown, the cross-sectional plane Fij in the case of 3-axis machining is defined as a plane perpendicular to the transfer vector Vij', where the transfer vector Vij' passes through the reference point Pij and connects the reference point Pij in the edge Ei The direction vector of , that is, the vector generated by transferring the reference vector Vij to a plane perpendicular to the depth direction (X ...

Abstract

To obtain an automatic programming apparatus, capable of generating a tool path for the chamfering process with a simple operation and capable of shortening the operation period and improving machining efficiency, the automatic programming apparatus includes a chamfering tool path generating unit and machining condition data. The chamfering tool path generating unit includes: a chamfered plane defining unit that generates shape data defining a chamfered plane obtained after the chamfering process is performed with respect to a shape of the chamfering target part; a reference point sequence generating unit that generates a reference point sequence used as a reference for generating the tool path data used for performing the chamfering process; and a tool reference position generating unit that, generates a reference position of a machining tool used when the machining tool passes while performing the chamfering process.

Description

technical field [0001] The present invention relates to an automatic programming device and an automatic programming method. When chamfering a material shape, tool path data for moving a tool to process can be generated through simple operations, and can be selected and chamfered. The chamfering method corresponding to the target part of the corner processing. Background technique [0002] After inputting the processing unit data for partial processing including data such as the shape of the processing area, processing method, tools used, and processing conditions, and generating control command information for operating the machine tool based on the input processing unit data In the automatic programming device, the chamfering process mainly removes the corners of the boundary part where adjacent surfaces intersect with each other. When the boundary part between curved surfaces is the object, the shape of the chamfered part becomes complicated. . Therefore, machining is g...
