　差異情報取得部４１は、算出部３３から出力された差異を取得し、当該差異を作業支援情報生成部４３に出力する。 The difference information acquisition unit 41 acquires the difference output from the calculation unit 33 and outputs the difference to the work support information generation unit 43.

　圧力情報取得部４２は、後述する圧力検出部６１の検出結果である研磨部６の圧力情報を取得し、当該圧力情報を作業支援情報生成部４３に出力する。 The pressure information acquisition unit 42 acquires pressure information of the polishing unit 6 that is a detection result of the pressure detection unit 61 described later, and outputs the pressure information to the work support information generation unit 43.

　作業支援情報生成部４３は、差異情報取得部４１により取得された差異に基づいて、ユーザーの研磨作業を支援する作業支援情報を生成し、当該作業支援情報を透過型表示部５に出力する。 The work support information generation unit 43 generates work support information that supports the user's polishing work based on the difference acquired by the difference information acquisition unit 41, and outputs the work support information to the transmissive display unit 5.

　作業支援情報としては、例えば、図４に示すように、差異情報における差異量を示す差異量情報が挙げられる。差異量情報は、形状情報と設計情報との差異量に応じて差異を色分けした情報であって、差異量が多いほど色が濃くなるように示される情報である。 As the work support information, for example, as shown in FIG. 4, there is difference amount information indicating the difference amount in the difference information. The difference amount information is information in which the difference is color-coded according to the difference amount between the shape information and the design information, and is indicated as the color becomes darker as the difference amount increases.

　差異量情報の内訳（図４において「差異量」と示された部分）は、透過型表示部５において差異量情報の脇に表示されるようにすることができる。差異量情報の内訳は、例えば、下から順にＡ，Ｂ，Ｃ，Ｄ，Ｅと並べられている。図４の例では、上に位置する情報ほど差異量が多い情報となっている。 The breakdown of the difference amount information (the portion indicated as “difference amount” in FIG. 4) can be displayed beside the difference amount information on the transmissive display unit 5. The breakdown of the difference amount information is, for example, arranged in the order of A, B, C, D, E from the bottom. In the example of FIG. 4, the information located on the upper side has a larger amount of difference.

　これにより、ユーザーが研磨対象物における各部位においてどの程度研磨すれば良いか確認しながら研磨作業を行えるので、研磨作業を精度良く行うことができる。なお、制御部４は、差異のみ、つまり、図４における差異量情報として色分けしていない部分の情報のみを透過型表示部５に出力するようにしても良い。 Thereby, the polishing operation can be performed while the user can perform the polishing operation while confirming how much polishing should be performed at each part of the object to be polished. Note that the control unit 4 may output only the difference, that is, only information of a portion not color-coded as the difference amount information in FIG. 4 to the transmissive display unit 5.

　作業支援情報生成部４３は、図５に示すように、差異量情報として示されている部分の研磨作業が終了した場合、その作業済み部分を、差異量情報の内訳として示されているＡ～Ｅにはない色に変換する。これにより、ユーザーが作業済み部分を容易に識別することができる。 As shown in FIG. 5, the work support information generating unit 43, when the polishing work for the portion indicated as the difference amount information is completed, indicates the completed portion as the breakdown of the difference amount information. Convert to a color not in E. Thus, the user can easily identify the part that has been worked on.

　また、作業支援情報生成部４３は、差異量情報、つまり、差異に加えて、圧力情報取得部４２により取得した圧力情報に基づいて作業支援情報を生成しても良い。圧力情報は、本発明の「研磨部に関連する情報」に対応する。 Also, the work support information generation unit 43 may generate work support information based on the difference information, that is, the pressure information acquired by the pressure information acquisition unit 42 in addition to the difference. The pressure information corresponds to “information related to the polishing portion” of the present invention.

　作業支援情報としては、図６に示すように、例えば、研磨部６により実際に加えられる加圧力、及び、加圧力と当該加圧力を研磨対象物に付与された時間とを乗算した力積が挙げられる。 As the work support information, as shown in FIG. 6, for example, an applied force actually applied by the polishing unit 6 and an impulse obtained by multiplying the applied pressure by the time applied to the object to be polished are applied. Can be mentioned.

　図６では、加圧力の部分において、左側が目標加圧力、右側が実際の加圧力を示している。また、力積の部分において、左側が目標力積、右側が作業してからの総力積を示している。 In FIG. 6, in the applied pressure portion, the left side shows the target applied pressure and the right side shows the actual applied pressure. In the impulse part, the left side shows the target impulse and the right side shows the total impulse after working.

　目標加圧力は、例えば、研磨部６における最適な加圧力を示し、目標力積は、研磨作業をしている部分を研磨し終えるまでに必要となる力積を示している。このような加圧力や力積に関する情報は、研磨対象物の材質、物性に対する研磨部６の種類等の組み合わせに関連する情報を予めデータベース化して制御部４により参照可能なようにしておくと良い。 The target pressing force indicates, for example, the optimum pressing force in the polishing unit 6, and the target impulse indicates the impulse required until the polishing operation is completed. For such information on the pressure and impulse, information relating to the combination of the material of the object to be polished, the type of the polishing unit 6 with respect to the physical properties, and the like may be stored in advance as a database so that the control unit 4 can refer to the information. .

　このように作業支援情報を透過型表示部５に表示させることにより、実際の加圧力と目標加圧力を比較しながらユーザーが作業できるので、研磨部６における最適な加圧力により作業を行うことができる。また、目標力積と総力積とを比較しながらユーザーが作業できるので、研磨対象物における研磨量を最適な研磨量とすることができる。 By displaying the work support information on the transmissive display unit 5 in this way, the user can work while comparing the actual pressure force and the target pressure force. Therefore, the work can be performed with the optimum pressure force in the polishing unit 6. it can. Further, since the user can work while comparing the target impulse and the total impulse, the polishing amount on the object to be polished can be set to the optimum polishing amount.

　透過型表示部５は、例えば、メガネ型のウェアラブルディスプレイからなり、ユーザーが頭部に装着することで、ユーザーに対して前方の研磨対象物を視認させながら、作業支援情報生成部４３を介して差異および作業支援情報を透過表示する。 The transmissive display unit 5 includes, for example, a glasses-type wearable display, and the user wears the head on the head so that the user can visually recognize the object to be polished ahead through the work support information generation unit 43. Display differences and work support information transparently.

　透過型表示部５には、研磨対象物に重畳して作業支援情報生成部４３から得られる差異および研磨作業支援情報をディスプレイ５１に表示させることが好ましい。その結果、ユーザーが実際の研磨対象物に対してどの程度研磨すれば良いか確認しながら作業することができるので、研磨作業における作業効率を向上させることができる。 The transmission type display unit 5 preferably displays on the display 51 the difference obtained from the work support information generation unit 43 and the polishing work support information superimposed on the object to be polished. As a result, the user can work while confirming how much the actual polishing object should be polished, so that the working efficiency in the polishing work can be improved.

　研磨部６は、ユーザーが操作することで研磨対象物を研磨するための公知の研磨装置であり、圧力検出部６１を有する。圧力検出部６１は、例えば、ロードセル等のセンサーであり、研磨部６から研磨対象物に加わる圧力情報を検出し、当該圧力情報を圧力情報取得部４２に出力する。 The polishing unit 6 is a known polishing apparatus for polishing a polishing object by a user operation, and includes a pressure detection unit 61. The pressure detection unit 61 is, for example, a sensor such as a load cell, detects pressure information applied to the object to be polished from the polishing unit 6, and outputs the pressure information to the pressure information acquisition unit 42.

　なお、各部における情報の送受信は、無線通信や有線通信により行われる。 In addition, transmission / reception of information in each unit is performed by wireless communication or wired communication.

　以上のように構成された本実施の形態によれば、透過型表示部５に、形状情報と設計情報との差異を表示させることで、ユーザーが前方の研磨対象物と当該差異とを重畳させた上で、研磨作業を行うことができる。 According to the present embodiment configured as described above, the difference between the shape information and the design information is displayed on the transmissive display unit 5 so that the user can superimpose the difference between the polishing object in front and the difference. In addition, polishing work can be performed.

　その結果、ユーザーが実際の研磨対象物に対してどの程度研磨すれば良いか確認しながら作業することができるので、研磨作業における作業効率を向上させることができる。 As a result, the user can work while confirming how much the actual polishing object should be polished, so that the work efficiency in the polishing work can be improved.

　また、作業支援情報を差異とともに透過型表示部５に表示させることにより、研磨作業を精度良く行うことができる。 Further, by displaying the work support information together with the difference on the transmissive display unit 5, the polishing work can be performed with high accuracy.

　また、作業支援情報に圧力情報（研磨部６に関連する情報）を含めることにより、理想の研磨作業に対する現状の研磨作業の差異を管理しながら研磨作業を行うことができる。そのため、研磨対象物における研磨量を最適な研磨量とすることができ、ひいては研磨作業を精度良く行うことができる。 Also, by including pressure information (information related to the polishing unit 6) in the work support information, it is possible to perform the polishing work while managing the difference between the current polishing work and the ideal polishing work. Therefore, the polishing amount in the object to be polished can be set to an optimum polishing amount, and the polishing operation can be performed with high accuracy.

　透過型表示部５にて、差異情報を研磨対象物に重畳して表示するためには、差異情報を研磨対象物の座標に紐付けさせる必要がある。例えば、図７に示すように、研磨対象物を固定した台座７の任意の箇所に施されたマーキングＭの位置を形状計測部２により検出させるか、又は、予め制御部４等に記憶させておく。 In order to display the difference information superimposed on the object to be polished on the transmission type display unit 5, it is necessary to associate the difference information with the coordinates of the object to be polished. For example, as shown in FIG. 7, the shape measuring unit 2 detects the position of the marking M applied to an arbitrary portion of the pedestal 7 to which the polishing object is fixed, or is stored in the control unit 4 or the like in advance. deep.

　形状計測部２等を介して得られた差異情報には前述のマーキングＭに相対する位置情報が付加される。透過型表示部５を具備するウェアラブルディスプレイには、図８に示すように、カメラ等の撮像部５２が付帯される。研磨作業をする際に、撮像部５２から取得されたマーキングＭの位置を、制御部４に設けられた位置情報取得部４４が随時特定する。 Position information relative to the above-mentioned marking M is added to the difference information obtained via the shape measuring unit 2 or the like. As shown in FIG. 8, an imaging unit 52 such as a camera is attached to the wearable display including the transmissive display unit 5. When performing the polishing operation, the position information acquisition unit 44 provided in the control unit 4 specifies the position of the marking M acquired from the imaging unit 52 as needed.

　位置情報取得部４４により特定されたマーキングＭに相対して差異情報が透過型表示部５に表示されるように制御部４が、作業支援情報生成部４３を介して表示内容を制御し、差異情報を透過型表示部５に表示する。これにより、透過型表示部５には、研磨対象物に重畳表示される形で差異情報が表示される。 The control unit 4 controls the display content via the work support information generation unit 43 so that the difference information is displayed on the transmissive display unit 5 relative to the marking M specified by the position information acquisition unit 44. Information is displayed on the transmissive display unit 5. As a result, the difference information is displayed on the transmissive display unit 5 in a form superimposed on the object to be polished.

　また、作業対象位置に対応した研磨作業支援情報により、研磨部６のマーキングＭに相対する位置が特定される。かかる位置とマーキングＭによって相対される位置の差異情報、作業支援情報が、制御部４により透過型表示部５に表示される。 Also, the position corresponding to the marking M of the polishing unit 6 is specified by the polishing work support information corresponding to the work target position. Information on the difference between the position and the position opposed by the marking M and the work support information are displayed on the transmissive display unit 5 by the control unit 4.

　このようにすることで、研磨対象物の研磨作業を行うときに、台座７のマーキングＭと透過型表示部５に表示されたマーキングＭに対応する情報とを重畳させることができる。そのため、研磨対象物と、透過型表示部５に表示された差異とを透過型表示部５内において正確に重畳させることができる。 By doing in this way, the marking M on the pedestal 7 and the information corresponding to the marking M displayed on the transmissive display unit 5 can be superimposed when the polishing object is polished. Therefore, the polishing object and the difference displayed on the transmissive display unit 5 can be accurately superimposed in the transmissive display unit 5.

　なお、上記実施の形態では、研磨部６に関連する情報として圧力情報を例示したが、本発明はこれに限定されず、例えば、研磨部６の性状であっても良い。 In the above embodiment, the pressure information is exemplified as information related to the polishing unit 6, but the present invention is not limited to this, and may be the property of the polishing unit 6, for example.

　また、上記実施の形態では、研磨部６が圧力検出部６１を有していたが、本発明はこれに限定されず、圧力検出部を有していなくても良い。 In the above embodiment, the polishing unit 6 includes the pressure detection unit 61. However, the present invention is not limited to this, and the pressure detection unit may not be included.

　また、上記実施の形態では、形状情報と設計情報との差異そのものを透過型表示部５に表示させていたが、本発明はこれに限定されず、例えば、形状情報と設計情報との差異部分の厚さの数字情報等を差異に関連する情報として透過型表示部５に表示させても良い。 Moreover, in the said embodiment, although the difference itself between shape information and design information was displayed on the transmissive display part 5, this invention is not limited to this, For example, the difference part of shape information and design information The numerical information of the thickness may be displayed on the transmissive display unit 5 as information related to the difference.

　また、上記実施の形態では、差異に関連する情報を研磨対象物と重畳できるように透過型表示部５に表示させていたが、本発明はこれに限定されず、当該情報を研磨対象物と重畳できないような表示させても良い。ただし、ユーザーによる研磨作業の効率向上の観点から、当該情報を研磨対象物と重畳できるように表示させることが望ましい。 Moreover, in the said embodiment, although the information relevant to a difference was displayed on the transmission type display part 5 so that it could overlap with a grinding | polishing target object, this invention is not limited to this, The said information is referred to as a grinding | polishing target object. You may display so that it cannot superimpose. However, from the viewpoint of improving the efficiency of polishing work by the user, it is desirable to display the information so that it can be superimposed on the object to be polished.

　その他、上記実施の形態は、何れも本発明を実施するにあたっての具体化の一例を示したものに過ぎず、これらによって本発明の技術的範囲が限定的に解釈されてはならないものである。すなわち、本発明はその要旨、またはその主要な特徴から逸脱することなく、様々な形で実施することができる。 In addition, each of the above-described embodiments is merely an example of actualization in carrying out the present invention, and the technical scope of the present invention should not be construed as being limited thereto. That is, the present invention can be implemented in various forms without departing from the gist or the main features thereof.
